Nāhuku Lava Tube

Really cool experience and a beautiful, easy walk. Parking was limited - we were lucky to get a parking spot on a Friday at 130 PM. Otherwise, you have to walk a bit from the overflow parking down the road. Bathrooms are a plus. Overall, highly recommend!

⭐️⭐️⭐️⭐️⭐️ Volcano Tubes – An Unforgettable Experience in Hawaii Visiting the volcano tubes in Hawaii was truly one of the highlights of our trip, and I can’t recommend this stop highly enough. The entire hike leading to the lava tube is absolutely beautiful — a perfect blend of lush rainforest scenery, cool shaded pathways, and that peaceful Hawaiian atmosphere that instantly slows your pace and makes you appreciate every step. The trail is well-maintained, accessible to most visitors, and filled with vibrant greenery, birdsong, and the kind of natural beauty that feels straight out of a postcard. The real centerpiece, of course, is the incredible lava tube itself. Walking through it feels like stepping into another world. The cool air, the soft echo of footsteps, and the natural volcanic formations lining the walls make it a one-of-a-kind experience. The lighting inside is just bright enough to show the tube’s details while still preserving that mysterious, awe-inspiring ambiance. It’s amazing to stand inside a place formed by molten lava thousands of years ago and imagine the power that shaped it. Whether you’re a nature lover, hiker, or someone seeking a memorable adventure, the volcano tubes are an absolute must-see. As a Local Guide, this is exactly the kind of spot I love highlighting — unique, accessible, and unforgettable. Highly recommend!

Parking spaces were available around 9:30 am and when we hiked back here around 11 am it will as packed with many busses on the side too. The walk is pretty quick and it is a dark tube that gets lit up between 8 am and 8 pm but if you have trouble seeing in the dark or want to see more then bring your own flashlight. The walk is short but getting down to the tube can be steep for some. Be careful. It's a very short walk for the loop.

We went after dark so we had to use the flashlight from our phones up until we got to the actual tube. Very nice short walk. Beautiful scenery leading up to the very well lit tube. Walkable for little ones. I had my two second graders with me. Very cool experience to add to our volcano visit! 🥰🌋

Got there at like 8.30am I think and had the tube to our self. Felt so cool being inside, great experience. Drove past later in day and it was packed, couldn’t get a carpark. Definitely go early if you have the time

The lava tube is fun and a natural experience! How often can you walk over a hundred feet through a tube that carried lava, without bending over? It was "One huge lava tube". Once down to the lava tube an easy walk on the path to and from the tube with many plants identified. Very limited parking! Not handicap or child friendly, with very steep stairs to the lava tube and uneven walking inside the tube.

Cool lava tube, not too busy! Would have loved to have seen it at night too. The loop is nice, stairs down and somehow you end up above it when you come out. Restrooms near the entrance/exit of the loop - one of the few with running water so take advantage!

Nāhuku Lava Tube – Big Island An incredible natural wonder worth visiting! Walking through the lava tube feels like stepping into another world — cool, mysterious, and full of history. It’s an easy stop inside Hawai‘i Volcanoes National Park and a great way to experience the raw power of nature up close. Definitely a must-see on the Big Island!
