California Caverns

Mountain Ranch is a very small town but here you will find the first cave in California to be opened to the public for guided tours California Caverns. It opened in 1850 and was known as “Mammoth Cave.”

Historical marker number 956 states: The historical significance of California Caverns is well established as a major cavern system and as one of the earliest officially recorded caves (1850) in the Mother Lode region of California. The early commercial enterprise associated with California Caverns is evidenced by the historical documents verifying organized tourist activities as early as 1854. Although one of numerous caves in the Mother Lode region, California Caverns claims the distinction of having the most extensive system of caverns and passageways.
