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.

Hikers going to see the flowing lava past the end of Chain of Craters Road, Hawaii Volcanoes National Park: Photo by Donnie MacGowan

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.

If you are planning on viewing the lava at night, be sure to remember that there may be no open gas stations or restaurants when you depart the Park until you reach either Kona or Hilo…plan accordingly, think ahead. Stay safe…stay awesome.

Our Big Island is geologically quite young and the landscape is immature, so our beaches tend to be smaller than those on the older islands, and are therefore all the more precious. What the Big Island has that some of the other islands lack, though, are beaches with spectacularly colored sand…white sand, black sand, green sand and even grey sand.

The creamy white sand beaches of picture postcards and hapa haole songs result from the accumulation of small particles of coral reef and crushed shell fish shells. As the reefs grow, wave and storm action break it into small pieces and many fish, such as the parrot fish and the humuhumunukunukuapua’a munch the coral, spitting-out sand sized particles, and the coral they swallow comes out…er…the other end as sand-size pellets of sandy waste. In this way, one coral-eating reef fish can produce up to a ton of white sand a year. Because our white sand beaches result from physical degradation of soft, biological material, the sand grains tend to have rounded edges. Thus, unlike sands derived from rock and mineral sources, such as the California beaches, they do not stack well and tend to produce poor sand castles.

Waialea Beach, or Beach 69, is an out-of-the-way gem that is rarely crowded on the Kohala Coast, Hawaii: Photo by Donald B. MacGowan

Beautiful white sand beaches occur all over the Big Island, but are biggest and best developed on the Kona and Kohala coastlines, as coral reefs prosper best on the lee-side of the island. Prime examples of white sand beaches include Anaeho’omalu, Hapuna, Waialea and Makalawena Beaches. Snorkeling at these white sand beaches is a joy—the water is a brilliant turquoise due to the amount of light reflected back into the water by the sandy shore bottom. However, this sandy bottom itself is relatively barren of life, so if seeing fish is your main snorkeling goal, be sure to choose a beach with a nearby reef, such as Waialea Beach, since the fish live in and around reefs and rocky cliffs.

Black sand beaches are strange and spectacular, and, because of their thermal properties, are warm even on a chilly day (Oh, yes, we do have chilly days here in Hawaii–in mid-winter temperatures can dip into the low 70s and even rarely the upper 60s!). In fact, it is the black sand beaches of the Big Island that are the choice among egg-laying female Hawaiian green sea turtles for laying their egg clutches on, precisely because of their warmth.

Littoral Explosions as Lava Enters the Sea at Waikupanaha, Puna Hawaii: Photo by Donald B. MacGowan

Black sand beaches result from the fiery, explosive mix of hot liquid lava entering the ocean. The skin of the lava stream is instantly chilled as it flows into the water and then blasted off when the ocean water flashes to steam. Black sand also results from mechanical action during the natural physical erosion of the basalt (the name for the rock our lava becomes once it cools). You’d think that sand forged in the volcano would be tough and enduring, but in truth, it’s very, very fragile and black sand beaches do not last long over time. For this reason, although the sand is beautiful and rare, we ask you not to take any home with you.

Kaimu Beach, Hawaii’s Newest Black Sand Beach, Near Kalapana, Puna Hawaii: Photo by Donald B. MacGowan

Black sand beaches occur all over the island… two of the largest are on the north end of the island, crossing the mouths of Waipi’o and Pololu Valleys, respectively. These are not visited as often as some of the others as both entail something of a hike down into the canyons. What once must have been a heart-achingly beautiful, large black sand beach fronts Hilo Town right on Hilo bay, but much of it has been eroded, polluted and degraded by industrial encroachment or simply paved over as a result of urbanization. By far the most popular black sand beach is at Punalu’u. Not only is the beach lovely, inviting and easily accessible, it’s almost guaranteed that the visitor will see Hawaiian Green Sea Turtles basking on this beach. The youngest and most vibrant black sand beach is Kaimu Beach at the end of the Kalapana-Kopoho Road. Kaimu beach, lovely if barren, is a crescent of sand that lies at the end of an unforgiving expanse of basalt from the 1990 flows. The old beach and the fishing village of Kalapana that once stood here are long gone, buried under 50-75 feet of lava—an unimaginable catastrophe

Black sand is made by the interaction of hot. liquid lava and cold ocean water, such as this littoral flow at Waikupanaha, Puna Hawaii: Photo by Donald B. MacGowan

Snorkeling at the black sand beaches can be dark and mysterious, as little light is reflected back into the water from the sandy bottom, but the bouldery nature of the off-beach sea floor assures the prospect of abundant life and many reef fish. Be aware…because black sand beaches mostly occur on the youngest, and therefore most exposed, portions of our island, many are characterized by big waves, strong currents and nasty rip tides. Swim only where you see others swimming, and only when a life guard is present.

Wild, surreal, enchanting, the Big Island’s green sand beaches are a rare geologic occurrence that appear in only a few choice spots on our island and almost nowhere else in the world. Although they take a little effort to get to, you should not travel all the way to Hawaii and not see these jewel-like beaches.

The olivine (also called peridot) crystals weathering our of the cinder cone make up the sand at Mahana Green Sand Beach on Papakolea Bay, Ka'u Hawaii: Photo by Donald B. MacGowan

The green sand is composed almost entirely of the mineral olivine, or peridot as the gem quality crystals are known. These crystals precipitate out of the molten lava while it sits in the magma chamber reservoir before it erupts onto the surface. The liquid lava is melted from rocks at great depth within the earth; the chemical composition of the melt is at equilibrium at extremely high pressures and temperatures. As the magma migrates upward, many miles, through the Earth’s crust, it cools and pressure decreases; this causes crystals to precipitate from the melt. In magmas world wide, olivine is almost always observed to precipitate out first.

Small but marvelous Mahana Green Sand Beach on Papakolea Beach at South Point, Ka'u Hawaii: Photo by Donald B. MacGowan

In Hawaii, lavas migrate up to the surface so quickly, and then are expelled from the magma chamber onto the surface so quickly, that usually they have little time for many crystals to form. But when lava does sit in the magma chamber awhile, the olivine crystals do precipitate, and they slowly settle to the bottom of the melt. As liquid lava begins to erupt onto the surface, much of the olivine is left behind in the residual liquid. Thus, lavas erupted from the latest stages of these magma chambers sometimes are enriched with crystalline olivine. Since late stage magmas are also relatively cooler and less fluid, their eruptions are more explosive and they tend to form more spatter cones than flows. The green sand beaches of the Big Island result where the ocean has breached one or another of these spatter cones, and the winnowing action of the waves has washed away all the particles except for the relatively denser olivine grains.

The intense color of the sand at Mahana Green Sand Beach makes the waters at Papakolea Bay a very strange, and reflects an eerie light back along the amphitheater walls, South Point, Ka'u Hawaii: Photo by Donald B. MacGowan

There are tiny green sand beaches all along the southern coastline on either side of South Point, but the largest and most accessible is Mahana Beach on Papakolea Bay at South Point, reached by a moderate hike of about 2 ¼ miles along the wild coastline northeast of South Point, following an old 4WD two-track. Because of the unique sand color, snorkeling at the Green Sand Beach is a must…underwater pictures, if you are equipped with a suitable underwater camera, are quite stunning. Just be careful of the treacherous currents, rip tides and big waves. This is the wild and open ocean and this side of the island is completely unprotected. Once again, due to its rarity and the irreplaceable nature of this resource, we ask that you enjoy our Green Sand beaches, but don’t take any sand home with you.

Warm, comfortable and inviting, grey sand beaches result from mixing of black sand particles with white sand along a stretch of beach and as such, are represented by a continuum of grey hues. In fact, many Big Island beaches probably fit more with a definition of grey sand beach than properly occupy either of the two distinct end member compositions, black sand or white sand beach. Ho’okena, Kahalu’u and Honomalino are three of the largest and most popular grey sand beaches on the Big Island. There is one entirely unique beach, Ke-awa-iki, which today is a dominantly black sand beach, but the black sand has incompletely mixed with the older white sand on the southern portion of the beach, leaving a stretch of strange, but oddly artistic, piebald black and white sand.
