Event Details


Puapo‘o Lava Tube is almost as large and open as Thurston Lava Tube (Nāhuku). Hikers will need to climb down a 15 foot (4.6 m) ladder into the tube, scramble over large, loose and slippery rocks and walk over uneven terrain with minimal light while in the lava tube. Hikers will also need to walk in a crouched position for about 25 feet (8 m) under a low, 4-foot (1.2 m) ceiling. The tube exit requires a fairly difficult climb/scramble up a pile of boulders.

This NPS tour is approximately 2 – 3 hours in duration.  For an in-depth (all day) exploration that includes lunch, commemorative coin and Certificate of Completion, check out our Wild Caves Exploration Institute brought to you by the Hawai’i Volcanoes Institute.
