California Cavern

California Cavern Review

A ½-mi subterranean trail winds through large chambers and past underground streams and lakes. There aren't many steps to climb, but it's a strenuous walk with some narrow passageways and steep spots. The caverns, at a constant 53°F, contain crystalline formations not found elsewhere, and the 80-minute guided tour explains local history and geology. Call ahead to check on hours of operation, which are subject to change.
