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 55 stairs to a combination of flat boardwalk, uneven surfaces and stairways. 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 any other cave or mine. Please wear close-toed shoes and warm clothing. Average temperature in the Cave is 42 degrees Farenheit.

We strongly enocourage visitors to bring or rent two light sources. This is the safest way to experience and enjoy the cave.
