Mitchell Caverns, tucked away in the isolated Providence Mountains within the Mojave Desert, is the only limestone cave system in the California State Parks. Situated at an elevation of 4,300 feet, it features two primary caves—El Pakiva (“The Devil’s House”) and Tecopa, named for a Shoshonean chief—connected by a man-made tunnel. Access is limited to guided tours led by California State Park rangers. Though pretty remote, it was conveniently located along our route home from Laughlin. We had advance reservations for the two-hour tour, and the $20 fee was well justified.
