There are many wondrous, enigmatic and fascinating attractions on the Big Island of Hawaii, some better known than others, many out of the way and generally off the beaten track. Tour Guide Hawaii has produced an encyclopedic collection of the most up-to-date information, presented as short GPS-cued videos, in an app downloadable to iPhone and iPod Touch that covers the entire Big Island, highlighting the popular and the uncrowded, the famous and the secluded, the adventurous and the relaxing.

It is obvious to even the most causal observer that various lava formations and lava fields of Hawaii display two distinctly different types of lava flows. Some flows are very smooth, with obvious, well-preserved flow structures, looking almost like poured taffy that has hardened. Others appear more clunky, clinkery and jagged like a field of sharp boulders and cobbles. These two unique rock types result from two distinctly different types of lava flows, Pahoehoe and A’a.

The onomatopoetic word “pahoehoe” flows across your tongue in the same fashion that pahoehoe lava flows down the volcano. Gelatinous and smooth, it looks a bit like small waves with bulbous, lobate “toes” at the front of the flow. As the advancing lobe cools, a thin crust forms on its surface. This crust is expanded and broken by the pressure of lava flowing in behind, in a continually advancing flow. A distinctive breaking-glass sound is made when that cooling crust fractures, which can be disorienting and surprising at first.

The Hawaiian word “pahoehoe” means “to paddle a canoe vigorously” or “well stirred” and indeed, pahoehoe lava has the look of water being furiously paddled by canoeists, or indeed, of well-stirred poi. These highly fluid pahoehoe flows form from the hottest lava with high dissolved fluid content. As the lava cools and de-gasses, the second kind of flow, a’a lava, is formed from it.

A’a flows travel along as a dense mass of highly viscous lava covered in sharp, broken shards called clinkers. Like a tractor tread, a’a clinkers fall off the advancing front of the flow and are buried as the flow moves forward over them, sounding for all the world like a herd of wild bulls has run amok in the world’s largest china shop.

A’a lava, which cools to great piles of razor sharp clinkers, has given rise to the myth that its name derives from Hawaiian’s walking across the cooled a’a barefoot, wincing and saying “Ah! Ah!” with every cringing step. In fact, the word “a’a” in Hawaiian not only means “to blaze or glow” but also “to dare or challenge”. It is a testament to the toughness of Hawaiian warriors that when choosing the site for a battle field, inevitably they chose to fight on an a’a field—using the razor sharp a’a strewn along the landscape as a weapon in and of itself.

Flows generally emerge from the volcano as pahoehoe and change to a’a as they cool and de-gas or as they are subjected to stress and strain forces. It is especially common to find pahoehoe flows changing to a’a in the midst of a steep drop over a cliff, or when butted-up against an impediment to flow. Like the cucumber becoming a pickle, once pahoehoe turns to a’a, in can never turn back into pahoehoe.

Where fire fountains and geysers of lava occur, Pele’s hair and Pele’s tears will form. Pele’s hair are thin, fiber-like strands of basalt glass pulled and spun from the lava fountain by the blowing wind,. Pele’s tears are the droplet-sized, cooled splashes of basalt glass that from from showering, spraying lava.

The Volcanoes of Hawaii Island

The Hawaiian Archipelago, part of the Hawaiian Island-Emperor Seamount chain, is the most isolated island group earth and is comprised entirely of volcanic islands and their fringing reefs.  The archipelago was formed as one of the Earth’s great tectonic plates, the Pacific Plate, moved steadily northwest over a stationary plume of molten material welling up from the Earth’s mantle, called a “hot spot”.

Creating a chain of volcanic islands that, today, stretches from the Aleutian Islands to the Big Island of Hawaii, this hotspot gave rise to at least 129 separate volcanoes in the past 86 million years.  There are 19 islands and atolls, and dozens of separate islets, seamounts, reefs and shoals in the Hawaiian Island portion of this chain, stretching from Kure Atoll to Hawaii Island (please go here for a complete discussion of the geologic history of the Hawaiian Islands).

Hawai’i is the youngest island in the Archipelago and first began forming about a million years ago as volcanic vents opened above the mantle “hot spot” on the ocean bottom and molten lava began pouring onto the sea floor. Over the centuries, the making of the Big Island as we know it today eventually entailed the growth and conjoining of six separate volcanoes, building all the way up from the seafloor, some 18,000 feet below the ocean’s surface.  These volcanoes, from northwest to southeast, are named Mahukona, Kohala, Mauna Kea, Hualalai, Mauna Loa and Kilauea, and become younger as one moves north to south.

Lava Flowing Into the Sea at Waikupanaha, Hawaii Photo by Donald B MacGowan

Mahukona Volcano, just off the Big Island’s northwest coast, was the first volcano to start forming. Now submerged beneath the surface of the ocean because it is sinking into the Earth’s crust under its own vast weight, Mahukona is no longer visible.  As the Pacific Plate slowly continued moving northwestward over the hotspot, the location of the rising magma moved relatively southeastward, and through time the rest of the Big Island volcanoes formed along that path.

Kohala Mountain from the slopes of Mauna Kea Photo by Donald B MacGowan

After Mahukona, Kohala Volcano, the precursor to today’s Kohala Mountain, erupted next.  As Kohala Volcano emerged from the sea and joined with Mahukona, a much larger Big Island began forming. With continued movement of the Pacific Plate, the center of volcanism migrated on to Mauna Kea and Hualalai, the middle-aged volcanoes, and finally on to Mauna Loa and Kilauea, which are the youngest volcanoes on the island.  Over the geologically short time of several hundred thousand years, these volcanoes erupted thousands of thin flows which spread over, and built upon, older flows; each volcano growing until it finally emerged from the sea. As time went on, lava flows from one volcano began to overlap flows from other, nearby volcanoes and eventually the peaks coalesced into a single island, the Big Island.

In geologically recent times, a new volcano, Lo’ihi, began forming about 18 miles off the southeast coast of the Big Island.  In time, Loihi may join its mass with that of Kilauea, again changing the size and shape of the Big Island.  It is estimated that Lo’ihi, whose summit lies approximately 3,178 feet below the surface of the ocean today, will begin to protrude above the surface in about 10,000 years.

Hualalai Volcano from Saddle Road, Hawaii Photo by Donald B MacGowan

Currently, the remnants of Mahukona and Kohala volcanoes are completely extinct; Hualalai and Mauna Kea are considered dormant and Mauna Loa, Kilauea and Loihi are still very active.   This means that eruptions of Mahukona and Kohala are not at all likely. Eruptions of Mauna Kea and Hualalai are probable at some time in the future, though the major phase of mountain building is over for these volcanoes.  Movement of the Pacific Plate has moved both Hualalai and Mauna Kea off the hot spot so only remnants of liquid magma reside beneath them. These late-stage, mature Hawaiian volcanoes experience violent, explosive eruptions which are spectacular but comparatively small, volume-wise.  Late-stage Hawaiian volcanic eruptions are characterized by crater-forming explosions, tephra-cone building and ash ejecting events.

Mauna Loa and Kilauea are both considered active volcanoes. Although inflation and dilation events are common on the summit of Mauna Loa, it has not erupted since 1984; Mauna Loa could, however, erupt at any time.  Since 1833 when accurate records began to be kept, there have been 33 eruptions of Mauna Loa, making it one of the most active volcanoes on earth.  Its name means “long mountain”, and Mauna Loa is capable of erupting huge amounts of lava in a very short time, dwarfing the current output of Kilauea.  The most massive mountain on earth, this prolific effusion of molten rock accounts for Mauna Loa’s vast bulk.

Kilauea, once believed to be a mere satellite vent on Mauna Loa, is known to be a separate and distinct volcano with its own, geologically separate magma chamber and subterranean plumbing. Nearly half a million years old, Kilauea’s most recent eruption has been continuous since 1983 making it currently the world’s most active volcano. Indeed, between 1983 and 2009 about 700 acres of new land were produced by lava flows from Kilauea.  Articles on how to see the active lava flows on Kilauea can be found here and here. A detailed guide to enjoying Hawaii Volcanoes National Park, featuring Kilauea and Mauna Loa Volcanoes can be found here.

Because the time-scale of human experience is virtually instantaneous compared to the aeons-long march of geologic history, there is continuing human drama, a tension, between short-sighted humans attempting to establish roads, villages and towns, and the ongoing geologic processes of the landscapes they choose to inhabit.  In very recent decades, the towns of Kapoho, Kalapana and Kaimu have been inundated, destroyed and buried by Kilauea Volcano (please see a related article on the death and rebirth of Kalapana, here).  As more people move to Hawaii, more such drama is inevitable.

The evolution of Hawaiian volcanoes continues even after the major phase of eruptive activity subsides. There are great differences, obvious to even the most casual observer, between the elongated, fluted ridge-like shape of Kohala Mountain and the lower angled slopes of Mauna Loa and Kilauea.  Likewise, steep-sided Mauna Kea has a greatly different physical aspect than does gently-sloped, shield-shaped Mauna Loa.  These differences are accounted for by the differences in their relative ages, and thus eruptive and erosive stages.

Remembering that the angle of repose of Hawaiian lava is about 6 degrees, the shield-shaped, gentle slopes of Mauna Loa and Kilauea reflect the fact that they are quite young and are still in the shield-building stage, being built-up by successive flows of highly fluid lava.  The much steeper flanks of Hualalai and Mauna Kea volcanoes are due to the late-stage, explosive eruptions, to erosion and to ashfall which piles up much more steeply than the flowing lava.  The fluted ridges of Kohala volcano result from the deep dissection of the once shield-shaped slopes of the original volcano by streams and surface flow of water.  The distinctive steep valleys and great cliffs seen on the north and east sides of Kohala Volcano result from later process of normal faulting and giant landslides (see further discussion in an article about Waipi’o Valley, here).

Another process, operative in the geologically recent past, has served to shape the slopes of the volcanoes of the Big Island, at least those which are or great height.  Glaciers covered the summit of Mauna Kea (and possibly Mauna Loa) three times between 200,000 and 13,000 years ago, leaving behind many glacial features such as cirques, u-shaped valleys and scoured bedrock; surviving into the present is a remnant rock glacier near the summit of Mauna Kea (a related article on the summit of Mauna Kea and the Hawaiian Snow Goddess, Poliahu, can be found here; details on exploring Mauna Kea can be found here).  Any evidence on Mauna Loa of ice-age glaciers has been covered by recent eruptions.

Simultaneously with the ongoing eruptions and island building, due to their enormous mass, the great volcanoes of the Hawaiian Chain begin to subside into the oceanic crust.  After the majority of eruptions cease, with cooling and with a great amount of time, they eventually disappear beneath the surface of the sea completely, as Mahukona Volcano already has.

Today, the Big Island of Hawai’i comprises more than twice the area of all the other Hawaiian Islands combined.  It’s size is not anomalous, however, considering the geologic history of the archipelago. All the other Hawaiian Islands experienced the same pattern of volcanic eruption, growth and coalescence, as well as the gradual subsidence and submersion that Hawaii Island has, and thus at one time may have been as large as the Big Island.  Indeed, geologists have demonstrated that Maui at one time formed a single landmass, known as Maui Nui or “Big Maui”, with the islands of Lana’i, Moloka’i, and Kaho’olawe.  Continued subsidence submerged the larger landmass, leaving the four, smaller islands above the ocean surface. Ultimately, this will happen to the Big Island, as well.

The relentless movement of the Pacific Plate carries it, with the all the islands piggy-backed, inexorably northward to the Aleutian Trench, where it is subducted underneath the North American Plate, melted, and recycled as volcanic material in the Aleutian Island volcanoes.  The Emperor Seamounts are currently undergoing such destruction, and, the evolution of the Hawaiian-Emperor Chain is such that, eventually this fate also awaits the Big Island…but not for tens of millions of years.

The Geologic History of the Hawaiian Islands

The Hawaiian Islands, part of a much longer chain of oceanic islands and seamounts called the Hawaiian-Emperor Chain, is comprised of 8 principal islands and 124 islets, shoals, atolls, seamounts and banks, all volcanic in origin.  The Hawaiian Islands proper extend from Kure Atoll in the mid-Pacific, trending southeast to Hawaii Island (the Big Island) and Lo’ihi submarine volcano.  The eight major islands of the Hawaiian chain are named, from northwest to southeast, Ni’ihau, Kauai, O`ahu, Moloka`i, Lana`i, Kaho`olawe, Maui, and Hawai`i. Unraveling the geologic history of the Hawaiian Islands provides a fascinating glimpse into structures and process occurring deep within our Earth.  To understand how the Hawaiian Islands were formed, let’s review a bit about the nature of our planet.

Layered like an onion, our seeming solid earth is actually a heaving mass composed of various solid, partially-molten, semi-plastic and liquid layers.  The solid crust (or lithosphere), which covers the entire surface of the earth, seems strong and robust but is, in fact, quite thin and malleable.  About the same thickness relative to the rest of the planet as an onion skin is to an onion, the Earth’s silica-rich crust more or less floats upon a much thicker, partially molten, more iron and magnesium-rich, semi-plastic layer of much hotter material called the “mantle”.  Below the mantle are the liquid outer core and the solid inner core of the Earth.

Earth’s crust comes in basically two varieties, oceanic crust which is quite thin (only 5-7 km thick) and continental crust, which is much thicker than oceanic crust (up to 200 km thick).  Oceanic crust is composed almost wholly of an effusive volcanic rock type called “basalt”, its intrusive volcanic, subsurface equivalent called “gabbro” and a thin covering of sediment. The continental crust, which underlies the seven continents and the more massive islands, and upon which most human activity takes place, on the other hand, is composed not only of basalt and gabbro, but all the other rock types as well.  Continental crust is much less dense than oceanic crust, being much more silica-rich, and therefore is more buoyant on the mantle.  This, in part, accounts for its relative thickness and higher elevation compared to the denser, thinner oceanic crust.

The Earth’s crust is further divided-up into various distinct pieces, called “tectonic plates”, all moving relative to each other. Plates are composed almost wholly of either oceanic or continental crustal material. These plates “float” on the semi-plastic mantle, and are carried along by currents on the mantle’s surface. Mantle currents are caused by various physical process of heat transport within the mantle.   Think of a pot of boiling soup; the point of the boil in the soup is analogous to the heat transfer in the mantle and the skim of chilled soup riding around on the surface is analogous to the moving tectonic plates carried on top of the mantle.

Interactions along the edges of these plates, whether slipping past each other (such as along the San Andreas Fault), one riding up over another (such as beneath the Himalayan Mountains), or one being subducted beneath the other (such as along the western edge of North America), accounts for much of the earthquake, mountain-building and volcanic activity seen on the surface of the earth, and plate margins are certainly the most geologically active places on earth.

Occasionally, exceptions to this generality occur, and the Hawaiian Islands are one such spectacular exception. To understand the forces and process which shape the Hawaiian Islands, we must look a little closer at the origin and movement of the crust and the structure of the mantle.  Happily, we need only concern ourselves with oceanic crust in general and the Pacific Plate in particular, as well as one, singular feature of the mantle.

Oceanic crust is continually created by volcanic action along giant ridges which run generally north-south down the middle of the ocean basins.  The hot liquid magma at the ridges is much less dense than the surrounding, cold crustal rocks, and so “floats” these ridges and the still hot, newly-formed oceanic crust, up above the surrounding ocean basin, thus forming the ridge.  As volcanic eruptions along these ridges add hot, new material to the edge of the oceanic plates, the mass of new material drives the older oceanic crust away from the ridge, down both sides of it.  As the new material cools and becomes less dense, it sinks and further drives the crust away from the ridges.

Called “Mid-Ocean Ridge Spreading”, this process can be likened to a conveyor belt where new crust is created at the mid-ocean ridge, and is driven along by buoyancy and gravity, farther and farther away from the ridge until the plate’s leading edge interacts in some way with another tectonic plate.  Thus we see that the floors of the ocean basins, all around the world, are in constant, relative motion.  The Pacific Plate, upon which the Hawaiian Islands are built, has been moving at a rate of about 3.9 inches per year to the northwest, relative to other plate motions, for about the last 42 million years.

But what causes the enormous volcanoes that comprise the Hawaiian Archipelago to form in the middle of the ocean basin?  As mentioned above, the mantle is far from uniform either compositionally, thermally or in terms of the processes controlling its internal motions.  There are places on the earth where, for a variety of reasons, hot and buoyant mantle plumes rise above the general surface of the mantle, into the crust, carrying great amounts of heat and semi-liquid material quite near the earth’s surface.  Called “Hot Spots”, extreme volcanism can result from these thermal plumes.  The volcanic fields at Yellowstone in North America are one such example of this “hot spot magmatism”; the Hawaiian Islands are yet another.

The Hawaiian Hot Spot has caused the creation of at least 129 volcanoes on the ocean floor, the center of volcanism on the Pacific Plate continually migrating across the plate as it travels over the hot spot. Of these 129 volcanoes, 123 are extinct, three are dormant and three are active.  At first, the trend of volcanoes was almost due north-south.  Then, somewhere between 41 and 43 million years ago the relative motion between the Pacific Plate and the hot spot changed, becoming more northwesterly; this caused a sharp bend in the line of island-forming volcanoes.

Although all were formed by the same, continuing tectono-volcanic processes, two island groups are named from this bent line of islands, atolls and seamounts.  North of the bend are the Emperor Seamounts, a long chain of islands, seamounts, atolls and reefs trending steeply southeast to northwest between Abbot Seamount in the mid-Pacific and Meiji Seamount near the Aleutian Trench.  South of the bend are the Hawaiian Islands, trending from the active volcanism at the Big Island and Loihi Volcano today, gently northwest to Kure Atoll in the mid-Pacific. Movement of the Pacific Plate over the hotspot is such that Midway and Kure Atolls were where the Big Island is now, directly over the hot spot, about 30 million years ago.

The steep sides of Mt. Rainier in Washington result from its relatively high-silica, viscous lava Photo by Donald B MacGowan

The chemical composition of the Hawaiian magmas plays a central role in determining the physical form of the Hawaiian Islands.  All crustal rocks are formed of minerals composed of aluminum and silicon oxides with varying amounts of iron, magnesium, sodium, calcium, potassium and other elements stirred in.  In lava, silica tends to polymerize and greatly increase the viscosity of the melt—thus silica-rich lavas are fairly “sticky”, forming slow moving lava flows that pile-up into steep volcanoes which are typified by explosive eruptions. Silica-poor melts, on the other hand, because they are not so polymerized, form very fluid lavas that flow quickly and easily, forming gently-sloped volcanoes typified by relatively quiescent eruptions.  Remember the key words here are: “relatively quiescent”.

One glance at the profile of the Hawaiian volcanoes is enough to convince us that the lavas must be very silica poor, since they are very gently-sloped and the eruptions relatively peaceable; certainly civilized enough so that the casual viewer may approach them quite closely in relative safety.  Compare these with the very steep-sided, highly explosive eruptions of volcanoes like Mt. St. Helens, which is comprised of lava much more intermediate in silica composition, or the smoking hole in the ground that is the Yellowstone volcanic field, left by a massively explosive, very silica rich (and very, very viscous) lava erupting.

The rocks formed when the lava from Hawaiian volcanoes hardens are called “basalt”.  Although you hear the term “lava rock” used by laymen, it is a nonsensical word geologically and the registered trademark of a commercial product.  Commonly misapplied, it makes even less sense than the equivalent of using the term “water solid” instead of “ice”. The name “basalt” denotes both the silica-poor composition, as well as the fact that it was erupted onto, and it has cooled at, the Earth’s surface.  When lavas cool within a magma chamber before being erupted onto the surface, they are called an “intrusive volcanic” rock; intrusive volcanic rocks formed from lavas of basalt-like composition are called “gabbros”.  There are a few rocks in the Hawaiian islands of differing composition and texture than basalt and gabbro, but they are unimportant to this discussion.

The classic, low-angle shield shape of Mauna Loa seen from Hilo, Hawaii Photo by Donald B MacGowan

The angle of repose, which is controlled by the viscosity of the melt, is about 6 degrees for Hawaiian basalts. Melt viscosity is a function of its temperature, silica content and fluid composition.   Hawaiian basalts are very fluid because of the low silica content and high eruptive temperature (in excess of 1100 degrees C); this low viscosity accounts for low angle, “shield shape” of Hawaiian volcanoes.

Kohala Volcano is dissected by several major fault-bounded valleys, further obscuring its original shield shape Photo by Donald B MacGowan

As soon as the Hawaiian volcano forms, other forces begin to act upon it, affecting the general “shield shape” of the volcano: tides and waves attack the edges, rivers and streams begin to dissect the shield into ridges.  As time goes on, erosion from surface water flow produces fluting along those ridges.  Great landslides produce enormous cliffs; faulting produces huge valleys and collapse produces enormous craters and calderas.  Further, the later stage of Hawaiian volcanism is typified by increasing violence, which makes deep explosion craters, steep-sided cinder cones and steeply sloped, but easily eroded, ash deposits.

Stream erosion dissects the shield volcanoes into valley and knife-like ridges Photo by Donnie MacGowan

To look at the volcanoes of Hawaii starting in the southeast at Kilauea and Mauna Loa and moving northwest, one can see this evolution quite clearly.  Kilauea and Mauna Loa, being quite young, are still broad and shallow-sloped, basically the classic shield-shape.  Mauna Kea and Hualalai are obviously more mature, showing steeper slopes, a reflection of greater ashfall and greater erosion, as well as pocked with explosion craters and cinder cones.  Moving father along, Kohala Mountain is so deeply eroded and festooned with long, fluted ridges as well as cut by enormous canyons, that it is almost unrecognizable as a shield volcano.  And so it continues as one proceeds north through the older islands and the more highly eroded mountains; the original shield shape of the volcanoes become more and more obscured by deeper and deeper erosion.  By the time one gets to the famous and spectacular Na Pali Cliffs of Kaua’i, all that is left of the original volcano are the deeply fluted, now almost knife-like, ridges.

Ancient Petroglyph, Keauhou Historic District, Hawaii Photo by Donald B MacGowan

The great mass of these volcanoes causes them to begin to sink back into the mantle.  This is evident on even relatively young volcanoes.  For instance, on the slopes of Hualalai Volcano on the Big Island, along the shore at Keauhou, numerous petroglyphs commemorating the famous victory of King Lonoikamakahiki of Hawaii over King Kamalalawalu of Maui were carved in the rock around the end of the 16th century.  Although when they were originally carved they stood above sea level, in the intervening four centuries, the island has sunk sufficiently that they are now mostly awash in the sea and submerged at high tide.

Another process, operative in the geologically recent past, has served to shape the slopes of the Hawaiian volcanoes, at least those which are or great height.  Glaciers covered the summit of Mauna Kea (and possibly Mauna Loa and Haleakala) three times between 200,000 and 13,000 years ago, leaving behind many glacial features such as cirques, u-shaped valleys and scoured bedrock; surviving into the present is a remnant rock glacier near the summit of Mauna Kea.

The complex interaction of volcano growth, coalescing of various volcanoes forming a single island and the eventual subsidence of the volcanoes into the crust determines the shape and size of the individual Hawaiian Islands through time.  Today, the youngest islands are largest and the oldest islands, generally, are the smallest…this trend continues throughout the Hawaii Island/Emperor Seamount chain.

In the case of the Big Island, even though the first volcano to form, Mahukona, has completely subsided below sea level, the Big Island still comprises more than twice the area of all the other Hawaiian Islands combined, due to the large number of volcanic peaks forming it. However, through their history, all the Hawaiian Islands will experience the same pattern of growth, coalescence, subsidence and submersion, and so may have been much larger at one time.

Haleakala from Kohala, Hawaii Photo by Donald B MacGowan

Maui, today comprised only of the remnant peaks of Haleakala and the West Maui Mountains, at one time formed a single giant landmass with the islands of Lana’i, Moloka’i, and Kaho’olawe.  As the continual northwest movement of the Pacific Plate carried Maui away from the Hawaiian hot spot, continued subsidence submerged the larger landmass, known as Maui Nui, or “Big Maui”, into the oceanic crust, leaving only these four, very much smaller, islands above the surface today.

Superstition to Science, Pu'u Weiku Summit, Mauna Kea Photo by Donald B. MacGowan

In fact, Kaua’i, Ni’ihau and O’ahu all represent the tiny remnants of once much larger landmasses that are actively subsiding into the oceanic crust.  Tracing the Hawaiian Archipelago to the northwest, and thus to very much older islands, we see this evolution continue as the great volcanoes are completely submerged below the surface leaving only the fringing coral reefs and a tiny remnant island above sea level, such as we see at Laysan Atoll and Midway Island. Continuing along through the chain to the Emperor Seamounts, not even that much is left as all traces of these islands, once proud and beautiful like the Hawaiian Islands today, become totally submerged beneath the surface of the ocean.

Add to this mental picture the fact that the Pacific Plate relentlessly drives northwestward, carrying all the Hawaiian-Emperor Chain with it, northward to the Aleutian Trench, where it is subducted and destroyed beneath the North American Plate.  Eventually, in the far-distant future, this fate awaits all these beautiful, precious islands.  Such is the ephemeral nature of the Hawaiian Islands, and this vision of their very delicate and temporary nature should make us respect and wonder at their splendor and beauty, all the more.  And increase our desire to protect and preserve them.

Can you believe this? It’s absolutely outstanding and amazing! You can actually walk right up to flowing lava here; see a volcano erupt before your eyes and the molten rock pour into the sea. This has to be one of the four or five most exciting, amazing, wonderful, mystical experiences on earth…you must not miss this!

Pu'u O'o Vent on Kilauea in Hawaii Volcanoes National Park: Photo by Shannon Walker

Mauna Loa is active but not currently erupting. The summit area is slowly inflating, filling with magma and the flanks are subject to frequent minor earthquakes, but no obvious activity is apparent to the visitor. Kilauea, the most active volcano on Earth, started its current eruptive phase in 1983, the longest eruption in history. Since then it has ejected almost 3 billion cubic meters of lava. Flowing from various vents in the rift, most notably Pu’u O’o and Kupaianaha, in streams and tubes at over 1000 degrees Celsius, much of the lava makes its way into the sea in fiery, steamy explosions or the incredible incongruity of glowing hot lava pouring directly into the sea with little more apparent than a mere bubbling of the water.

Since the flow of lava over the moonscape plains and into the roiling sea can be seen nowhere else on earth, it is certainly the most exciting, unique and moving highlight of any trip to Hawai’i. People stand at the edge of the flow and weep at the majesty and mystery of the earth remaking itself; it is wondrous, remarkable and unforgettable. Although surface flows and breakouts are frequent and common, there is no guarantee that over any given trip to the Big Island they will be visible or easily accessible to the casual visitor. Before planning a hike to see the lava, check with the Rangers at Hawaii Volcanoes National Park for information on the hike length and location of surface flows and a review of safety information. Eruption information is available from the Park Service at 808.985.6000.

Over the months and years, the lava river issuing from Pu’u O’o winds its way back and forth across the lava plain of about 9 miles breadth, sometimes flowing into the sea within Hawaii Volcanoes National Park, sometime outside the eastern margin of the Park on County of Hawaii land, sometimes ponding behind the low lava hills for weeks at a time without entering the ocean at all. When you check with the rangers about flow conditions, they can tell you the best way to approach these flows.

If the flows are toward the more western margin and within the Hawaii Volcanoes National Park, the best approach is to drive to the end of Chain of Craters Road in the Park and then hike in. This hike can be of a few minutes, or a few hours, duration, depending upon how far away the lava ocean entry is. Talk to the rangers beforehand so you can come prepared. The hike is over an uneven, rough surface, hot during the day, even when it rains, cold at night and navigation can sometimes be counterintuitive. When lava is flowing in the park, parking can be monstrous at the end of Chain of Craters Road; please go here for more details about visiting the end of the road.

Hiking to the lava ocean entry, Hawaii: Photo by Donald MacGowan

The trail at first is marked with cairns and reflectors, but after a few hundred meters you are on your own to navigate the basalt wilderness. The good news is, even if the hike is a couple hours duration, when the lava flow is in the National Park, you are allowed to walk right up to it; this is not true if the lava is flowing in the more eastern margin, onto County of Hawaii land. In this case, viewing is from a County of Hawaii-maintained viewing platform at Waikupanaha. Information on viewing the lava flows from County of Hawaii land is available here and from the County of Hawaii at 808.961.8093.

Rain squalls are common at lava ocean entries in Hawaii: Photo by Donnie MacGowan

Whether you approach the lava flows from the west or the east, bring at least 2 quarts of water, a flashlight for hiking out in the dark, camera, food, first aid kit and a light rain jacket; wear a sun hat, sturdy hiking shoes, long pants and a long-sleeved shirt–those rocks are sharp! Sun glasses and sunscreen are a must here; in fact, they are so important in tropical Hawaii, we ask you please go here and here for information on skin and eye protection. Over the years, we have found a stout hiking stick and an umbrella to be of good use as well. Since photos and video are most spectacular at night, it is wise to bring a camera tripod.

The lava seems to glow with only a dull petulance during the day and may be less than inspiring until nightfall brings it alive and the madly glowing, fiery goddess within is revealed. Thus knowledgeable hikers plan their hike to commence in the afternoon, reaching their destination at dusk, and then hike back in the dark. Check your flashlights before you leave the car and replace weak batteries. Remember that you are hiking on a highly active volcano, if flowing streams of lava strand you, no rescue is practical or possible; plan, take care and pay strict attention accordingly.

Obviously, the lava is lethally hot and sometimes flowing mere inches below seeming solid ground; a stick or ski pole used as a probe helps you determine what is dangerous ground and what is merely “hot and squishy” but otherwise safe to walk on. This is also why you should wear boots, not running shoes or sandals—it only takes having your sneakers catch fire once to drive this point home. When in hot terrain, never stop moving your feet. Even when you are standing still to photograph, walk in place or you may find your shoes afire.

Warning signs at the end of Chain of Craters Road, Hawaii Volcanoes National Park: Photo by Donald B MacGowan

There are other dangers to hiking on the lava plain that might not be obvious to the casual visitor. The steam clouds generated by the lava entering the sea contain fine, glassy particulate material as well as sulfuric and hydrochloric acids in concentration high enough to aggravate the very young and old, expectant mothers and people with respiratory and cardiac conditions. Over the past 20 years, a few adventurous people venturing too close to vents or the sea entries have asphyxiated from toxic gasses.

The ocean near the lava entries is superheated and waves lapping on inviting black sand beaches can be scalding hot. One brave (foolhardy?) surfer wanted to be filmed surfing in front of the lava flows and was badly scalded for his efforts. Where explosive, the meeting of molten rock and sea can explode large, searing hot rocks hundreds of feet in the air and throw boiling water, splashing everywhere.

Methane explosions occur with no notice, dozens if not a hundred feet ahead of flows, flinging huge blocks hundreds of feet. Unstable benches that build up into the sea, and upon which the unwary hike and pause to photograph the scenery, are prone to collapse, carrying all into the sea. Such collapses can cause local tidal waves which scour the landscape clean of everything as they pass. Thin lava crusts can hide lava tubes, caves, hollows and holes into which hikers occasionally fall and are caught.

A volcano is a naturally highly seismically active area and earthquakes are common (there are over 1200 measurable earthquakes a week on the Big Island). Less common, but certainly a constant threat, are local tsunamis generated by these earthquakes. The Park Service has roughly marked the trail to the lava; follow it closely, turning around frequently to acquaint yourself with landmarks for the hike back.

Be sure to take extra film or memory cards for your camera and remember to wipe down all cameras, eyeglasses, binoculars, optics and electronics after your visit; the salt and volcano effluent-laden atmosphere is highly corrosive. Batteries may be drained faster than expected due to the high heat near the lava; bring extra for cameras and flashlights.

Despite the inherent dangers of hiking over liquid rock, steaming and unstable ground along the ever-restless sea, very few hikers are injured here, even fewer are killed. This is only because people enter the goddess’s home with a sense of awe and great caution, and the Rangers are very good about instilling fear and trepidation into the hearts of those who think themselves otherwise immune to the mortal dangers presented here. If you go, remain cautious and vigilant, plan for adversity, think ahead and pay attention. The rewards for this are a moving and amazing experience few ever have, a memory of mystery, awe and wonder to treasure always.

Nestled picturesquely, though precariously, in the narrow saddle between the summits of two highly active volcanoes, Kilauea and Mauna Loa, Volcano Village dozes gently. The town is a green oasis of vineyards, homes, shops, restaurants, even a golf course to play and a winery to tour. Of course, there are a host of inns and bed and breakfast establishments here as well.

Although its position seems perilous, Volcano Village’s setting is actually fairly serene and protected from all but the most explosive of eruptions from Kilauea and Mauna Loa, and the prevailing trade winds keeps the town swept fairly free of vog, volcano smog. Lying amid at least four mini-climatic zones in Hawai’i’s peculiar compressed geography, half the Village is shaded by primeval fern trees unfurling in mountain mist in the 2-tiered, cloud jungle. The other half is guarded by scraggly ohi’a trees rising from the dry savannah grassland of the Ka’u Desert. The enchantment of discovery is what makes Volcano Village a magical and surreal place to visit.

Although purchases in Volcano Village tend to be spendy, the Village represents the only opportunity to buy gas, food and water on the 42-mile stretch between Pahala and Mountain View during the day. Be sure to top off your tank of gas and load up on food and water before venturing into Hawaii Volcanoes National Park. Many people become quite entranced with the Park, spending a great deal more time and gasoline there than they had planned, and forgetting that there is little of anything available after dark on the south side of the island between Hilo and Kona.

Tour Guide Hawaii has produced an encyclopedic collection of the most up-to-date information, presented as short GPS-cued videos, in an app downloadable to iPhone and iPod Touch that covers the entire Big Island, highlighting the popular and the uncrowded, the famous and the secluded, the adventurous and the relaxing.

Mauna Ulu, or “growing mountain” is a still steaming, tall, shield-shaped hill formed by numerous eruptions along the rift between 1969 and 1974. Mauna Ulu is best seen by walking beyond the parking lot to where the end of road is covered in fresh lava flows. At Mauna Ulu, visitors can get an intimate look at both pahoehoe and a’a lava flow types.

Pahoehoe, the less viscous and generally hotter liquid flow, moves fluidly like a river or glacier, the surface folding and molding, like poured taffy, into a ropey structure. Pahoehoe forms generally flat, fairly smooth, hard surfaces. A’a, on the other hand, is much cooler and has exolved much of its dissolved gas, so it is much more viscous, causing the upper surface to fracture into clinker-like boulders and fragments. Flowing a’a sounds and looks like a moving pile of hot glass shards; when it cools, it leaves behind rubbly piles of sharp fragments. Fields of pahoehoe and a’a make a landscape that look as if Madame Pele has bulldozed her land to flat surfaces, but left these acres of boulder piles here and there.

The hike to the summit of Mauna Ulu is fabulous and rewarding. However, it is a long, dry, serious hike with some dangers (rock fall, crater collapse, scalding steam and others) and should only be undertaken by those in good physical condition and experienced at hiking cross-country across broken and hazardous ground.

Pu’u Huluhulu (“shaggy hill”) is a 150 foot tall cinder cone formed in pre-contact times between Mauna Ulu and Pauahi Crater. There is a fascinating 3 mile round trip hike from the Mauna Ulu parking lot to the top of Pu’u Huluhulu that is marked by cairns (or “ahu”). The round trip hike from Mauna Ulu Parking lot to Pu’u Huluhulu and return takes about an hour and a half to two hours. From the vantage point of Pu’u Huluhulu’s summit are fine views of Mauna Loa, Kilauea, Mauna Kea, the coastline and the very interesting, active cinder cone, Pu’u O’o (hill of the bird”), about 5 miles away.

Pu’u O’o was built by the fire-fountains erupting along Kilauea’s rift zone between 1983 and 1986. Since 1986, the center of eruption has moved about 2 miles further down the rift to a vent called “Kupaianaha”, or ”mysterious” in Hawai’ian. However, within the maw of Pu’u O’o is an active lava lake, which serves as a window into the plumbing of the eruptive rift system.

The entrance to Hawaii Volcanoes National Park is about 4200 feet elevation and one may enter in a driving sleet storm or freezing fog only to find oneself in the baking tropic desert of Holei at the end of Chain of Craters Road only forty minutes later. Expect rain, warm and cold; expect sun, warm and cold, and bring appropriate clothing and use it.

Food is only available in the Park at Volcano House, and occasionally at the end of Chain of Craters Road at a small concession stand. There are a number of restaurants and shops in Volcano Village to buy food and drinks, where the only gas near the Park also is available. It is wise to fill-up the gas tank and the food cooler before entering the Park. No matter what your plans may be, you are likely to spend more time and use more gas in the Park than you had originally intended.

The end of the Chain of Craters Road is currently around Mile Marker 19, just at the Holei Sea Arch and about ½ mile from the National Park eruption viewing station. Good, if distant, viewing of the eruption, displays about the volcano and natural history of the area, as well as a wealth of information on hiking to, and viewing, the lava, are available here. In addition, numerous sea arches, sea caves, fabulous bird watching, indescribable ocean views and some pretty good biking are to be found here. Even if the lava flows are too far away to be easily hiked to, the hike along the new land, twisted lava forms and endless basalt landscape is well worth the drive to the end of the road.

Over the months and years, the lava river issuing from Pu’u O’o winds its way back and forth across the lava plain of about 8 miles breadth, usually flowing into the sea within Hawaii Volcanoes National Park, but sometimes outside the eastern margin of the Park on County of Hawaii land at Waikupanaha, sometimes ponding behind the low lava hills for weeks at a time without entering the ocean at all. Check with the rangers about flow conditions; they can tell you the best way to approach these flows. Current eruption updates are available from the National Park Service by calling 808.985.600. Listen to their advice, heed their warnings, especially if you plan to hike all the way to the lava flows.

When the flows are within the Hawaii Volcanoes National Park, the best approach is to drive to the end of Chain of Craters Road in the Park and then hike in. This hike can be of a few minutes, or a few hours, duration, depending upon how far away the lava ocean entry is. The hike is over an uneven, rough surface, hot during the day even when it rains, cold at night and navigation can sometimes be counter-intuitive. The trail at first is marked with cairns and reflectors, but after the viewing station located at a few hundred meters, you are on your own to navigate the basalt wilderness. The good news is, even if the hike is a couple hours duration, when the lava flow is in the National Park, you are allowed to walk right up to it; this is not true if the lava is flowing onto County of Hawaii land at Waikupanaha.

When the lava is flowing, rangers are generally present at the end of Chain of Craters Road, Hawaii Volcanoes National Park: Photo by Donald B MacGowan

The End of the Road is the second busiest area in the Park when the lava is flowing. Rangers try to be available here to talk to visitors through most of the day and into the evening. The Rangers will have the most up-to-date information about hiking to, and viewing, the eruption. Due to the popularity of this area, it is not uncommon to have to park as much as ¾ of a mile or more from the end of the road.

Hiking to the lava flows, Hawaii Volcanoes National Park: Photo by Donald B MacGowan

You should bring at least 2 quarts of water, a flashlight for hiking out in the dark, camera, food, first aid kit, sun screen and a rain jacket; wear a sun hat, sturdy hiking shoes, long pants and a long-sleeved shirt–those rocks are sharp! Over the years, we have found a stout hiking stick and an umbrella to be of good use as well. Since photos and video are most spectacular at night, it is wise to bring a camera tripod.Remember: you will be hiking out at night; plan and pack accordingly.  There will likely be no food or gasoline available for purchase after dark  until you reach Hilo or Kailua Kona.

Hiking all the way out to the active flows is one of the most spiritually rewarding, awe-inspiring, curiosity quenching and amazing things one can do anywhere in the world—but it is neither for the physically unfit nor the meek of spirit. It is a long, hot hike over broken ground and glass-sharp rocks; the heat from the volcano is savage; the weather, if clear, is sweltering…frequent squalls blow in off the ocean and the rain and wind can get pretty wild out on the lava plain where there is absolutely no cover or shelter to protect you. No water or shade are available anywhere along the hike.

The molten lava itself is mortally dangerous, although slow-moving and easy to outpace. However, the incautious and inattentive can find themselves surrounded and cut off as flows advance whilst they are looking elsewhere. It is a good idea to use a sturdy walking stick or ski pole to probe in front of you, as you approach the active flows. Although it may appear dark and solid—especially in the bright daylight—much of what you will be walking on is still extremely hot and may not be completely hardened—best to probe it first before walking out on it. You only have to have your running shoes catch fire once to learn the wisdom of wearing sturdy boots here. Don’t be tempted to touch, spit on, sprinkle water on, poke, kick, throw rocks into or interrupt or molest the molten lava flow in anyway—the results will be blindingly fast, inexplicably unpredictable and agonizingly painful.

Remember that you are hiking on a highly active volcano, if flowing streams of lava strand you, no rescue is practical or possible; plan, take care and pay strict attention accordingly. The section on Lava Viewing has a great deal of important information regarding hiking on this active volcano; be sure to review it so that you may approach the home of the goddess with respect, knowledge and awe, and return unscathed.

From Kona, connect to Highway 11 south 2 1/2 hours to Ka’u Desert Trail. A 40 minute round trip hike leads to footprints of ancient warriors who where caught in a sudden, ferocious eruption. Continue on Highway 11 to Hawai’i Volcanoes National Park. Park Rangers at the Visitor Center will have the latest lava information. Chain of Craters Road has numerous craters, tons of hiking trails and several breathtaking vistas for great photographs. Upon exiting the Park, continue through Puna to Kea’au and Highway 130 (food stop). Proceed to Pahoa and the junction to Highway 132 and Lava Trees State Park. Here trees were inundated with fast flowing lava. When the trees rotted, it left these Lava Trees. Then on to Highway 137, following the coast past Ahalanui Hot Spring to Kalapana and a 20 minute hike to the lava viewing area at Waikupanaha. (Arrive about dusk for optimal viewing.) From Kalapana back to Kona is a 3 1/2 hour drive (after dark).

Leg 1) Start at north end of Keauhou Historic District on Ali’i Drive, head south on Ali’i Drive to jct with Kamehameha II Hwy; east on Kamehameha III to Hwy 11. Take Hwy 11 south to Ka’u Desert/Warrior Footprints Trail.

Keauhou Historic District and Kona Coffee

For almost 400 years, temples and palaces along the Kona coastline served as a kind of “Rome of the Pacific”, a great political, religious and cultural center in Polynesia, until the capital was moved to Honolulu in 1850 by Kamehameha III.

The most important, interesting and best preserved historical and cultural sites lie within the Keauhou Historic District, between Kahalu’u Beach Park in Kailua running south 6 miles to Kuamo’o Bay in Keauhou. The District contains perhaps a dozen fascinating sites that are easy to walk to, well maintained and quite interesting. To see the numerous fascinating and important archaeological sites in the Keauhou Historic District, it is necessary to park your car in the free parking at either Kahalu’u Beach Park or the Keauhou Beach Resort and explore on foot.

Just uphill from the Historic District is the Kona Coffee District. Hawaii is the only state in the union which produces coffee, and Kona coffee is perhaps the finest in the world. Over 2 millions pounds of coffee a year are produced on about 600, 2-3 acre farms; tours of coffee farms and roasteries are available.  More about Kona Coffee can be found here.

Ka’u Desert Trail and Warrior Footprints, Hawai’i Volcanoes National Park

Just where Hawai’i Belt Road enters Hawaii Volcanoes National Park from the West, is a small parking strip that is the gateway to a host of wonders within the Ka’u Desert section of Hawaii Volcanoes National Park. Although eruptions here are generally characterized by leisurely outpouring of lava, it is not unknown for Kilauea to violently erupt in a blast of steam and ash. It is this ash that preserves some human footprints, believed to have been formed in 1790 when enemies of Kamehameha the Great were caught by one such massive, explosive eruption. Perhaps as many as 400 men died in this eruption. An emergency phone is available here; there are no other services. Do not venture from your car here without carrying water. More about the Warrior Footprints and the hike can be found here.

Leg 2) Continue south on Hwy 11 to Hawaii Volcanoes National Park Entrance and jct with Crater Rim Drive; Crater Rim Drive west to Kilauea Visitor’s Center to Jagger Museum, then back around Crater Rim Drive to Kilauea Iki Crater.

Hawai’i Volcanoes National Park is a magical, spiritual, wondrous, strange and beautiful place comprised of great contrasts and contradictions: dry as dust desert to teeming tropical jungle; frigid sub-arctic wasteland to steaming black sand beaches to rivers of flowing lava.

The star attractions in the Park are a pair of active volcanoes; Mauna Loa is the largest mountain on earth and Kilauea is most active volcano on earth. However, there are numerous other wonders from lava tubes to crawl down, black sand beaches with sea turtles to watch, mysterious petroglyph fields to explore, tropical jungles to hike through, endangered bird species to find, happy-face spiders to amuse and an otherworldly volcanic landscape so fresh it’s still steaming.

Hawaii Volcanoes National Park is open 24 hours a day, 365 days a year. During daylight hours, an access fee is charged. The Visitor Center has a 24-hour information line at 808.985.7017 and there is a 24-hour eruption hotline at 808.985.6000. Within the Park tune to A.M. radio 530 for continuous information broadcast. There tourist items available for sale and one restaurant and in the park, however generally shopping, restaurants and gasoline are only available in the nearby village of Volcano.

Newly remodeled and updated, the Kilauea Visitor’s Center is an outstanding resource of information on Hawaii’s volcanoes and the National Park; the not-to-be-missed first stop in the park you must make. The Center is run by enthusiastic and knowledgeable staff that has the most up-to-date information on viewing the eruption, hiking and camping, bird watching, stargazing and just about any other topic of interest to Park visitors.

Available for sale in the Center are maps, guidebooks, books and videos about the volcanoes, Hawai’iana, history, plants and every topic you can imagine pertinent to the Park, even souvenirs. There are free brochures and pamphlets on various trails, attractions, hiking safety and lava viewing hazards and precautions. The Visitor Center is open daily from 7:45 a.m. to 5 p.m.; there are public restrooms, water and pay phones available. Starting at 9 a.m. and showing every hour on the hour is a 20 minute informative movie about the Park; the film changes from time to time, but always contains spectacular footage of eruptions, information on volcanology and the natural and human history of the Park.

Famed for its fabulous views of Mauna Loa and Kilauea as much as for its interesting exhibits, The Jagger Museum (named for geologist Thomas A. Jagger) is open daily from 8:30a.m. to 5:00p.m. Exhibits include murals by Herb Kawainui Kane, seismograph charts of eruptions and earthquakes, geological displays and display about the natural and human history of the Park.

When entering the parking lot of the Museum/Observatory, be especially careful of the Federally-protected Hawaii Goose, the Nene, who seem to congregate here. The Nene is the State Bird of Hawai’i, and this parking lot and its surrounding area constitute one of the best places for viewing them.

Kilauea Iki Trail

Perhaps the finest short day hike in the park, a four-mile, 2-3 hour trip down into, across and back out of Kilauea Iki Crater gives one an intimate feel for volcanoes, Hawaiian-Style. Along one side, thick fern and ohi’a forest skirts along the rim and on the other, lush tropical rainforest crowds to the very brink of the crater; bleak volcanic desert lines the crater walls and covers the floor. The start and finish of the hike are along well marked, wide trails. The remainder is an easily followed, well marked trail with stone ahu (cairns) over the crater floor. As always when hiking in the Park, it is wise to avoid the noonday sun, and to remember that afternoon showers are common, especially near where this hike meets the crater rim. More about hiking the Kilauea Iki Trail can be found here.

Leg 3) Crater Rim Drive to intersection with Chain of Craters Road; Chain of Craters Road to End of Road.

Most years, it is possible to hike to see flowing lava from the end of Chain of Craters Road in Hawaii Volcanoes National Park: Photo by Donnie MacGowan

The end of Chain of Craters Road is currently at the 19 mile marker near the Holei Sea Arch. This is where the road was cut off by flowing lava and destroyed the 2 million dollar visitor center. When the lava is near the road, one can walk right up to it. There are displays about the volcano and natural history of the area, as well as a wealth of information on hiking to, and viewing, the lava, available here.

Hiking all the way out to the active flows is one of the most spiritually rewarding, awe-inspiring, curiosity quenching and amazing things one can do anywhere in the world—but it is neither for the physically unfit nor the meek of spirit. It is a long, hot hike (currently seven miles) over broken ground and glass-sharp rocks; the heat from the volcano is savage; the weather, if clear, is sweltering…frequent squalls blow in off the ocean and the rain and wind can get pretty wild out on the lava plain where there is absolutely no cover or shelter to protect you. No water or shade is available anywhere along the hike.

Leg 4) Follow Chain of Craters Road back uphill to Crater Rim Drive, follow Crater Rim Drive back to Park Entrance and then to Hwy 11. Go east on Hwy 11 to jct with Hwy 130 at Kea’au; take Hwy 130 south to Pahoa.

Puna District and Pahoa Town

Remember...Puna is wet! The Malama Market sign is reflected in a rain puddle in downtown Pahoa, Puna Hawaii: Photo by Donald B MacGowan

Uncrowded, off the beaten track and largely undiscovered by tourists, Puna District is a magnificent wonderland; from incredible tree-tunneled roads, geothermal fields of steam vents, lovely beach parks, hot ponds, hikes on raw lava flows and jungle trails, and unequaled snorkeling, the land cries out for the visitor to explore a little bit.

At the center of Puna is Pahoa Town; wild, untamed and even a bit unruly, with its false-front, western-style buildings and raised wooden sidewalks, Pahoa looks more like it belongs in Wyoming. But Wild West isn’t the only subculture evident here…tie-dye banners and the general “flower-power” ambiance some businesses and citizens lend Pahoa give it a decidedly “’60’s” feel.

It has been said of Pahoa that if it weren’t for counter-cultural influences, it would have no cultural influences at all. The charm and allure of this way of living is evident when you consider that the region around Pahoa is the fastest growing portion of the island. Pahoa has some of the best restaurants on the island, THE best natural foods store and a great public pool.

Remember that the return leg of this trip to Kona will be made at night .  There is no food or gas available between Kea’au in Puna and Kailua Kona, so be sure to fill-up the tank and buy plenty of food while you can.

Leg 5) At Pahoa, get on Hwy 132 to Lava Trees State Park.

Lava Trees State Monument

Under a lacy canopy of monkeypod trees, casts of ohi’a trees stand as monuments to a fast-moving pahoehoe lava flow that passed through here in 1790. When the lava hit the water-saturated ohi’a trees, it cooled and began to congeal around them. The original ohi’a trees burned away but the quickly cooled lava around them stands here today, hollow, with imprints of the tree bark inside. Lava Trees Park offers trails to hike and a restful, bird-filled jungle to sit and listen to. You can spend between 20 minutes to an hour wandering the trails, here, exploring and discovering. Be careful, however, the area is riddled with hidden cracks in the ground which can make exploring hazardous. You may wish to avail yourself of the restrooms here; they are the last public facilities for some distance. You can find more about the Lava Trees Monument and the famous, lacy, canopied roads of Puna here and here, respectively.

Leg 6) From lava Trees State Park take Hwy 132 to jct with Hwy 137 at Kapoho; take Hwy 137 southwest to Ahalanui Pond then to Kaimu Black Sand Beach and Kalapana Disaster of 1990.

Ahalanui Pond

Also called “Secrets Beach”, this spring and ocean-fed, man-made pool was initially constructed when the springs ran chilly cold. Eruptions in Puna during the ‘50s and 60’s reworked the subterranean waterworks and now the springs run hot and the pool is a comfortably warm 90-95 degrees. The open connection to the ocean, keeps the water fresh. With the gentle aloha breezes, swaying palms and surf whooshing against the, it can be really hard to drag oneself out. Soak for a while. Picnic tables, pavilions, pit barbecues, showers, lawns and all the pleasantries of a civilized park are available at Ahalanui Pond. Leave no valuables in your car and be vigilant if you stay soaking here, after dark.  There is more about Ahalanui Hot Spring and pool here.  You can find information about nearby Issac Hale Beach Park and Pohoiki Bay here.

Kalapana Disaster of 1990/Kaimu Black Sand Beach

In 1990 the volcano goddess Pele determined it was time for some serious housecleaning in Puna. Lava flows from Kilauea’s East Rift engulfed the villages of Royal Gardens, Kaimu and Kalapana, destroying virtually everything.

Buried were a centuries old fishing village and a world famous black sand beach. When the lava came, it wiped out not just material possessions; it wiped out a way of life and a landscape cherished by generations. The Big Island’s newest black sand beach, Kaimu Beach, is a lovely if barren crescent of sand at the end of an unforgiving expanse of lava from the 1990 flows. The trail to the new black sand beach is marked with hundreds of young palms, numerous lava casts which include palms, pandanus fruit and even some fish that were caught in tide pools.

From the lava hillocks along the trail you can get nice views of the eruption plume at Pu’u O’o, up on the flank of Kilauea, as well as the steam clouds down a few miles along the coast where the lava enters the sea. Restrooms and fast food are available at the end of the road. More about Kalapana and Kaimu Black Sand Beach can be found here.

Leg 7) From Kalapana, take Hwy130 (Ahia Road) just a tweak to the jct with old HWY 130; go west on old the highway to Waikupanaha Lava Viewing.

Lava Viewing Near Kalapana

Nowhere else can you see lava flowing from a volcano into the sea; no Big Island visit is complete without seeing this awe-inspiring show. Currently lava is only flowing into the sea outside the Park. Drive south on Highway 130 through Pahoa to the 20 mile marker and take the right branch about two miles to the parking area. Port-a-potties are available here. The road is open from 2 p.m. until 10; no cars allowed in after 8. Lava viewing information is available from Hawaii County at 808.961.8093; check conditions before you go.

The easy trail, a 20 minute stroll to the viewing area, is well-marked. The viewing varies as lava flows nearer or farther from the trail. Viewing is best at dusk so bring flashlights for the hike out. Take close-toed walking shoes and a hat, long pants and long-sleeved shirt, at least 2 liters of water and sun block and a rain jacket and camera. Remember food and gas are not available anywhere nearby after dark, so fill up BEFORE you park, bring snacks and drinks. There are port-a-potties available at the parking lot.  Much more about lava viewing at Waikupanaha can be found here.

Leg 8) Return to Hwy 130; Hwy 130 north through Pahoa to Kea’au and jct with Hwy 11. Hwy 11 west to Kailua Kona. Take Hwy 11 west to Kailua Kona.

Remember that this leg of the journey takes about 3 1/2 hours, you will be driving it in the dark and there is nothing in the way of gas or food available between Kea’au and Kailua Kona at night.  If you find yourself low on gas and hungry at the end of the trip, the best bet is to drive into Hilo (about 1/3 hour away through Pahoa, get gas and eat there, then drive back to Kailua Kona on Highway 19 through Waimea.
