Historic cavern with stunning formations, underground lakes, and boat rides deep beneath the foothills.
California Cavern near San Andreas is one of the Sierra foothills’ most spectacular underground experiences. Discovered during the Gold Rush, the cavern features stunning limestone formations — crystalline stalactites, flowstone curtains, and rare helictites.
