A Hidden Gem in Hawaii Volcanoes National Park
If you’re planning a trip to the Big Island of Hawaii, the Thurston Lava Tube, also known as Nāhuku, should be at the top of your itinerary. Located inside Hawaiʻi Volcanoes National Park, this natural lava cave offers a rare chance to walk through a tunnel formed by flowing lava thousands of years ago. As a travel photographer and traveler, I found this experience both humbling and visually inspiring — a literal and figurative journey into Hawaii’s volcanic heart.
What Is the Thurston Lava Tube?
Lava tubes form during volcanic eruptions when flowing lava develops a solid crust on the surface while molten lava continues to move beneath. Eventually, the lava drains away, leaving behind a hollow tunnel.
The Thurston Lava Tube was formed by a past eruption from Kīlauea, one of the world’s most active volcanoes. This geologic formation is a stunning reminder of how the Big Island’s dynamic landscape has been shaped over time by fire and earth. The tube is easily accessible and offers a family-friendly, short hike through lush rainforest and into a surreal, subterranean world.
How to Get to the Thurston Lava Tube
The lava tube is located in Hawaiʻi Volcanoes National Park, accessible from Highway 11. After entering the park, head toward the Kīlauea Visitor Center and check in with park rangers for trail updates or safety information — volcanic activity can affect trail access.
The Nāhuku Trail to the lava tube is a short, paved loop through dense tropical rainforest. It’s an easy-to-moderate walk, though good walking shoes and water are still recommended. Along the way, you’ll pass volcanic steam vents and breathtaking crater views.
Entering the Lava Tube: A Step Into Hawaii’s Volcanic Past
The entrance to the Thurston Lava Tube appears modest — a dark, arched tunnel carved into the volcanic rock and surrounded by dense forest. As you descend, the temperature drops, and the sunlight gives way to soft, artificial lighting installed for safe exploration during the day.
Stepping into the lava tube feels like entering another world. The silence, cool air, and echo of footsteps create an almost sacred stillness. For photographers, this contrast between bright rainforest and dark cave offers a compelling opportunity to capture both natural beauty and geological drama.
Inside the Lava Tube: What to Expect
Once inside, you’ll walk through a tunnel lined with smooth, black lava rock. The passage opens into high-ceilinged chambers and narrows in other spots, requiring a bit of bending and careful footing. Some areas are wet from ceiling drips, while others are dry and dusty. This mix of textures and formations makes the lava tube an incredible subject for low-light photography.
Key features inside the Thurston Lava Tube:
- Polished lava walls that glisten under the light
- Jagged formations revealing the lava’s movement
- Natural soundscapes of dripping water and echoes
- Side chambers that hint at deeper volcanic pathways
If you plan to visit later in the day or want to explore deeper sections, bring a flashlight or headlamp to experience the cave in its natural darkness.

Photography Tips for Lava Tube Exploration
As a travel photographer, capturing the Thurston Lava Tube requires planning. Here are a few tips:
- Camera Gear: I use a Leica Q3, which excels in low-light environments with its 47.3MP full-frame sensor and fast f/1.7 lens.
- Use a tripod if you’re shooting in manual mode — the dim light can make handheld shots tricky.
- Capture contrast: Frame shots that show the juxtaposition between rainforest and lava rock.
- Play with shadows: The tunnel’s natural lighting creates dramatic highlights and textures.
