Nahuku - Thurston Lava Tube Hawaii Volcanoes National Park, HI 96718

"It is an interesting experience to walk through a lava tunnel, and it is not something most people will ever get to experience for themselves, so given the opportunity to do so, it should not be overlooked. It's full length is just short of a football field, but still fun to do, especially with kids. Parking can be a real issue, so as an option, park at the trailhead parking lot prior to reaching the lot directly in front of the tunnel itself. If you do so, it's a 10 minute hike on a fairly easy trail. Not a bad walk in its own right, and it saves you the added aggravation of dealing with the crazy parking situation."

"Highly suggest this stop while on Hawaii’s Volcanos National Park. The park does have an entry fee and they highly suggest you pre-pay online since cell coverage can be spotty depending on your service on the park. Parking by the lava tubes can fill up quickly but this is a must stop. It is a bit of a track downhill and with inclines . I do not suggest if you need assistance walking. It’s is in a slight rain forrest and can get wet and slippery. Bring a flash light, the light on your phone is NOT sufficient and in the tube it self there are many puddles. Beautiful scenery walking down to the tunnel. Then the tunnel itself (has some lighting) is an amazing sight of mother natures power! We did not have a flashlight, and may do but stepped in many puddles, and it made for a difficult walk to the end. There were stairs at the end, leading to a trail, but we decided to go back the way we came in case that drill was longer than we would want."

"Amazing views. We parked in the first lot and did the .5 mile hike which was very easy. You can drive further down to the lower parking garage lot which doesn’t require the hike. Fantastic views and the lava tube was amazing as well. Parking requires a fee, Wear sturdy shoes and a light rain jacket."

"A very quick in and out experience to see the lava tube! It is very dim inside and a quick walk through. All of my photos were taken on a night time mode setting to capture the beauty. No lines or a wait time. Parking is limited in the front of the trail entrance."

"A ten minute walk down to the lava tube was easy and paved(there are some stairs). The cave is about 1/4 mile long before an even easier walk back to the parking lot. A quick and unforgettable stop. (Park pass required. Costs $30 per week for all Hawaii parks access)."
