Lava Beds Information

At the Lava Beds National Monument visitors can explore more than 500 lava tube caves, created over the last half-million years by volcanic eruptions.

Lava Beds National Monument is a land of turmoil, both geological and historical. Over the last half-million years, volcanic eruptions on the Medicine Lake shield volcano created an incredibly rugged landscape punctuated by cinder cones, lava flows, spatter cones, lava tube caves and pit craters. These lava tube caves, of which there are more than 500 in the Monument, are a favorite underground destination for visitors to explore.
