The Puapo‘o Lava Tube Tour is a moderate to challenging ranger guided hike through a tropical rain forest and fragile lava tube. 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 & Friends of Hawai‘i Volcanoes National Park ranger/FHVNP certified guided tours only. Tours will be offered once a week and 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. Reservations will be required at least one-week in advance. In addition, due to high interest, reservations are restricted to no more than four (4) people per group.

Tours are available once per week (NPS and Friends alternate weeks)
