Lava River Cave Interpretive Site

  

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.

Interpretive Areas

The scarcity and spaciousness of Central Oregon's Lava Lands create an area of striking beauty both above and below ground. Large areas are covered by lava flows. These rivers of rock consist of basalt which is a molten lava that spreads quickly and sometimes flowed up to 70 miles. Great tunnels wind through many of these flows and suggest that awesome forces of nature were once at work. These ancient lava tunnels (called tubes) are one of the area's most interesting secrets.
