Lava River Cave

Go Spelunking at Lava River Cave

Switch on your lantern or flashlight and carefully descend 55 metal stairs to the Lava River Cave. A short drive from Sunriver, the Lava River Cave is a must-do on a hot summer day to cool off. It’s also a memorable experience to walk through the mile long ancient lava tunnel that is 50 feet wide in some places.

The Lava River Cave has three ecosystems: the warm, dry climate just outside the entrance; the warm, moist microclimate at the entrance and the cool, moist, dark environment inside the cave. Once inside the cave, the trail is flat with some rocks — be sure to wear closed toe shoes. Much of the cave can be traveled standing up, though at the end some adults may need to duck to walk under.

It takes about an hour and half to tour the entire cave — it’s an out and back walk — so be sure to bring two light sources. The cave temperature is a constant 42 degrees. Dress warmly, even in the summer!

The cave is open seasonally, so check with the Lava Lands Visitors Center for the schedule. Lantern rentals are available for $5 until 4 pm.
