Event Details

The Wild Cave Exploration Institute is an in-depth, moderate to challenging guided exploration through a tropical rain forest and fragile lava tube. Led my expert scientists and naturalists through our Hawai’i Volcanoes Institute, you will have the experience of a lifetime. Special care is required when entering the lava tube to insure the preservation of this unique Hawaiian lava tube and its features. Access is restricted to National Park Service & the Hawai’i Volcanoes Institute through Friends of Hawai’i Volcanoes National Park. The Wild Cave Program will be offered every other week and is limited to 12 persons/group. Due to the fragile nature of the lava tube and the moderate/challenging nature of the tour, youth under the age of 7 are prohibited. Your registration is confirmed upon payment.

Pua Po‘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.

Before exploring the wild caves – Pua Po’o we will learn about the rainforest, discover native species and have many opportunities to take photos, listen to the birds sing and so much more.  After we explore the lava tubes, we will enjoy a picnic lunch, talk about what we discovered, and receive the Certificate of Completion and souvenir.

Hiking Times and Distances:

  • The hike is 5 miles roundtrip (8 km) with a 500 foot (152 m) elevation change.
  • Allow 6 hours for this wild cave program. Time spent in lava tube will be 2-3 hours.

 WHEN: Every other week (Wednesdays and Saturdays)
