Calaveras County Moaning Caverns
Calaveras is steward to four spectacular show caverns, and exploring these underground gems is a true adventure in admiring Mother Nature’s finest handiwork. Stalactites and stalagmites galore! Black Chasm, Moaning, Mercer and California Caverns provide thrilling spelunking experiences year-round. Try a 165-foot rappel down to the bottom of Moaning, discover deep black lakes in California, view unique crystalline formations in Mercer, and witness rare helictite formations in Black Chasm.
CCR Insider: If you’re a true thrill seeker, try Moaning Cavern’s twin zip lines! For the more placid, gem mining is also available at many of the caverns.
