Explore the Stunning Fossilized Lava Terraces in Hawaii

Hawaii’s volcanic landscape isn’t just about fiery eruptions; it’s also about the mesmerizing beauty of preserved lava flows. These solidified rivers of former molten rock create unique terraces, offering an unparalleled geological experience. These fossilized lava terraces, particularly striking in certain locations across the islands, reveal details about the type of lava flow, reveal how the Hawaiian volcanoes gradually shape each island’s coastlines. Let’s explore these geological marvels and discover the best spots to witness them firsthand.

The Formation of Lava Terraces

Understanding how lava terraces form is crucial to appreciating their rarity and significance. When lava flows enter the ocean, the rapid cooling creates a unique geological process. As molten lava meets the ocean’s cool water, a crust immediately forms. Behind this hardened band, new lava builds additional layers. Over time, this creates step-like formations, much like giant staircases made of stone. These “steps” are the lava terraces.

The type of lava greatly influences the terrace appearance. ‘A’ā lava, which is rough and blocky, produces terraces that are correspondingly rugged. Pahoehoe lava, smooth and ropey, creates more elegant and gently sloping terraces. Knowing which type of lava built the terrace gives valuable clues about the eruption history of the area.

Beyond the basic cooling process, other factors, like wave action and sea level changes also play roles. Storm surges can erode the newly formed terraces, while a gradually falling sea level exposes previously submerged lava flows, making the terraces more visible. The location of the lava flow in relation to the volcano’s vent matters, too. Flows further away may be thinner and form less pronounced terraces than those closer to the source.

Where to Find Stunning Lava Terraces in Hawaii

While lava terraces can be found on all the main Hawaiian islands, some areas are exceptionally renowned for their remarkable formations. Let’s explore some of the most accessible and impressive sites:

Volcanoes National Park, Big Island

The Coastal Section of Chain of Craters Road: One of the most accessible and well-maintained sites, this area offers stunning views of lava flows meeting the sea. The hardened lava fields extend towards the ocean exhibiting lava terraces. Take Highway 11 south from Hilo. Enter the park (entrance fee applies). The Chain of Craters Road starts near the Kilauea Iki Overlook. Drive down the road until you reach the coastal area. The road eventually ends at a point where you can hike towards the lava flows. The paved road lets you drive right up to many of the excellent viewing points, and hiking trails give access to the fossilized lava terraces up close. This is perhaps the easiest spot to get an intimate view of how volcanic activity reshapes the Big Island’s coast. There’s an entrance fee to the park, and parking can be limited, especially during peak hours. Check the National Park Service website (NPS) for alerts about road closures, safety advisories, and eruption updates that could impact accessibility.

The Pu’u Loa Petroglyphs: This area, known for its ancient rock carvings, also boasts fascinating lava formations. Hike inland from the coastal end of Chain of Craters Road, past the ‘Holei Sea Arch’ overlook turn left with the flow of traffic and drive for 3.6 miles. You will find the petroglyphs on the left-hand side of the road. Pu’u Loa, translating to “long hill”, is a significant area with over 23,000 petroglyphs etched into the lava rock. The hike is relatively easy, but be sure to wear closed-toe shoes as the terrain can be uneven and volcanic rock is sharp. Be respectful and avoid touching the petroglyphs, as oils from your skin can damage them. The lava terraces here provide a unique backdrop to the rich cultural history of the site.

Kona Coast, Big Island

Kiholo Bay: This area is a treasure trove of geological features, including lava terraces, anchialine pools, and remnants of past lava flows. To get here, drive north from Kailua-Kona on Highway 19, and turn west onto the unmarked dirt road just north of mile marker 81. Proceed down a rough lava road (high clearance recommended, but 2WD is often sufficient) to the parking area. It’s a moderately challenging, but rewarding hike to get to the bay. The diverse landscape around Kiholo Bay offers ample opportunities to observe how various lava flows interacted with the ocean. The terraces, coupled with the unique ecosystem of anchialine ponds (pools of brackish water), make it a fascinating destination. Wear sturdy shoes and bring plenty of water as the terrain can be hot and dry.

Ka’ena Point, Oahu

The Northwestern Tip of Oahu: Ka’ena Point, on the westernmost tip of Oahu, offers dramatic coastal views with distinctive lava terraces. The access to Ka’ena Point State Park is through Farrington Highway. You need to drive west past Waianae toward the end of the paved road. From there, you’ll need to either hike or drive (with a permit for four-wheel-drive vehicles) along a rough road to reach the point. Obtain a permit by completing an application and submitting it to the Hawaii Department of Land and Natural Resources. The permit does not guarantee access as it is based on availability. Once at the point, you’ll be rewarded with views of the ocean meeting the lava formations. The area is a sensitive ecosystem, home to nesting seabirds and endangered monk seals. Stay on designated paths, do not disturb any wildlife, and pack out all trash. The views of the western coastline are breathtaking, especially during sunset.

Poipu Coastline, Kauai

Spouting Horn Park: Although primarily known for the blowhole created by wave action through lava tubes, the surrounding coastline offers views of lava terraces. Drive south on Highway 50, then turn left onto Lawai Road, following the signs to Spouting Horn. Parking is available at the park. The force of the water creates an audible roar and shooting spray that make for dramatic viewing. You’re on top of lava formations, with views of terraces along the coast. This is an easy spot to access, with paved walkways and viewpoints. However, stay within the designated viewing areas, as the cliffs can be dangerous. Watch for humpback whales during the winter months (November to May), as they often frequent the waters off the Poipu coast.

Tips for Exploring Lava Terraces Safely

Exploring lava terraces can be an unforgettable experience, but safety must be your top priority. Here are some tips to ensure your adventure is both enjoyable and safe:

Wear Appropriate Footwear:

The lava surfaces are uneven, sharp, and can be slippery, especially when wet. Closed-toe shoes with good traction are essential. Hiking boots or sturdy sneakers are highly recommended.
Stay Hydrated: Hawaii’s tropical climate can be dehydrating. Bring plenty of water, even on short hikes. Carry at least two liters of water.
Protect Yourself from the Sun: The sun can be intense, especially on the exposed lava fields. Wear sunscreen with a high SPF, a hat, and sunglasses.
Be Aware of Your Surroundings: Watch out for uneven footing, loose rocks, and potentially dangerous wildlife. Always stay on designated trails and heed warning signs.
Check Weather Conditions: Weather in Hawaii can change rapidly. Check the forecast before heading out, and be prepared for rain, strong winds, or high surf.
Respect the Environment: Lava formations are delicate and can be easily damaged. Do not climb on the formations and avoid disturbing the surrounding ecosystem. Pack out all trash and leave no trace behind you.
Never Turn Your Back to the Ocean: Waves can be unpredictable, especially on rocky coastlines. Be aware of rogue waves and never turn your back to the ocean. A seemingly calm ocean can suddenly unleash a powerful wave.
Know Your Limits: Don’t attempt hikes or climbs beyond your physical capabilities. If you’re not comfortable with heights or uneven terrain, choose easier trails.
Tell Someone Your Plans: Before embarking on your adventure, tell a friend or family member where you’re going and when you expect to be back. This is a good safety precaution, especially if you’re hiking in remote areas.
Be Prepared for the Unexpected: Carry a small first-aid kit with essentials like bandages, antiseptic wipes, and pain relievers. A flashlight or headlamp can be useful if you get caught out after dark. Consider carrying a portable charger for your phone.

Experiencing the Cultural Significance

The Hawaiian people have a deep connection to the volcanic landscape, viewing it as both a source of creation and destruction and is central to the Hawaiian way of life. The volcanic goddess Pele resides within the volcanoes and her presence remains to be feared and admired. The lava terraces, are more than just geological wonders; they’re integral to Hawaiian mythology and history. Ancient Hawaiians skillfully used the lava rock for building homes, heiau (temples), and agricultural terraces. Evidence of these structures can still be found near many lava flow areas.

While exploring the lava terraces, take a moment to reflect on the cultural layers of the landscape. Look for signs of ancient settlements. Be sure to view responsibly and respectfully. Avoid touching or disturbing any potentially historic relics. Education about the Hawaiian culture enriches the experience, so take the time to read signs or consult local sources to learn more.

The ‘A’ā vs. Pahoehoe Lava: How to Tell the Difference

Understanding the two primary types of lava found in Hawaii – ‘A’ā and Pahoehoe – is key to fully appreciating the lava terraces. Each type creates distinctly different features and textures.

A’ā Lava: ‘A’ā (pronounced “ah-ah”) is characterized by its rough, jagged, and blocky surface. As it cools, the surface breaks into spiny, clinker-like fragments. The name ‘A’ā originated from the sound people made (“Ah! Ah!”) when walking barefoot across this painful surface, hence the name’s origin. ‘A’ā lava often flows faster and is more viscous (thicker) than Pahoehoe. It can be found in steeper slopes, forming rugged terraces with sharp, uneven edges. Exploring ‘A’ā flows requires extra caution due to its challenging surface, so ensure you apply the safety tips above.

Pahoehoe Lava: Pahoehoe (pronounced “pah-hoy-hoy”) is known for its smooth, undulating, and ropy surface. Its higher temperature and lower viscosity allow it to flow more easily and form smooth, rounded shapes, sometimes resembling coils, ropes, or even swirling art. Pahoehoe flows often create gently sloping terraces with a smoother appearance. It’s far easier to traverse than ‘A’ā, yet still requires footwear.

Being able to identify these lava types will enhance your observations. Look closely at the terrace surfaces and edges. Is it smooth and wave-like (Pahoehoe) or rough and jagged (‘A’ā)? Recognizing these features grants a deeper understanding of the geological history of the islands and the volcanic forces and events that shaped them.

Photography Tips for Capturing the Beauty of Lava Terraces

Lava terraces offer incredible photographic opportunities, but capturing their true beauty can be challenging. Here are a few tips to help you get the best shots:

Visit During Golden Hour:

The soft, warm light of sunrise and sunset (golden hour) enhances the textures and colors of the lava formations. This light accentuates the undulations and shadows, creating a more dramatic and visually appealing image.
Use a Polarizing Filter: A polarizing filter reduces glare and reflections, allowing you to capture the true colors of the lava rock and the surrounding landscape. It also helps to deepen the blue of the sky and the ocean.
Experiment with Different Angles: Try shooting from different vantage points to find the most interesting perspective. Get low to the ground to emphasize the textures of the lava, or climb to a higher vantage point to capture panoramic views of the coast.
Include a Human Element: Adding a person to your photos can provide a sense of scale and help to convey the vastness of the landscape.
Focus on Details: Don’t just focus on the grand vistas. Look for interesting details in the lava formations, such as cracks, patterns, and textures. Use a macro lens or zoom in to capture these details.
Use a Tripod: A tripod helps to stabilize your camera, especially in low light conditions. This will result in sharper images.
Be Patient: Wait for the right moment, the right light, and the right composition. Photography is about capturing a moment in time, so be patient and let the moment come to you.
Protect Your Equipment: Salt spray and volcanic dust can damage your camera equipment. Use a lens cloth to clean your lenses and carry your camera in a protective bag when you’re not using it.
Consider Black and White: The stark contrast of black lava against the blue ocean can create stunning black and white images. Experiment with converting your photos to black and white to see if it enhances the mood and impact of the shot.

Exploring From a Distance

For those who aren’t able or prefer not to hike to locations where lava terraces are accessible, helicopter tours can offer incredible perspectives. Several companies offer helicopter tours over Volcanoes National Park and other coastal areas, with the best aerial views. However, the cost to fly in a helicopter in Hawaii varies by island, tour duration and operator, from around $300 (1-hour tour) to over $800 (2–3 hours tour). This is an awesome option, but it won’t allow you that intimate exploration of the lava.
