Take a self-guided, mile-long discovery tour of Oregon’s longest intact lava tube. Central Oregon’s unique geological landscape offers ample opportunity to step back into time, but the Lava River Cave gives visitors the chance to step down into time. Down 150 stairs to be exact. That’s how far below ground this 5,211 foot lava tube snakes through the Earth, giving you a chance to see (with the help of a lantern) a truly remarkable natural phenomenon.
Bring a coat! Even in the summer, the cave stays at roughly 42 degrees, which can be a bit chilly if you’re wearing shorts and a tank top.
