Explore a mile-long lava tube. Lava River Cave offers self-guided exploration of a mile-long lava tube. It takes approximately 1.5 hours to tour the entire cave. Initial access descends 150 stairs to an uneven floor and can be challenging. In the interest of preventing the spread of White-nose Syndrome to bats that reside in the Cave, we ask that you not wear or bring into the cave any clothing or gear you have used in a cave or mine outside of Oregon or Washington. Please wear close-toed shoes and warm clothing. Average temperature in the Cave is 42 degrees Farenheit.
