Moaning Cavern

Located in Vallecito, CA, Moaning Cavern received its mysterious name from what some believe to be a moaning sound from the cave that lured gold miners to the entrance in the 1850s. Today, visitors can take a walking tour or rappel down a 165-foot-tall vertical shaft located in the cavern’s main chamber. Moaning Cavern is home to some of the oldest humans remains discovered in America; it is the final resting place for the bodies of prehistoric people who fell into its opening.
