About Moaning Caverns Adventure Park

Moaning Caverns Adventure Park in Vallecito features guided underground tours through California's largest single cave chamber, accessible via a metal spiral staircase descending over 165 feet into marble formations of the Calaveras deposit. The Spiral Chamber Tour takes 45 minutes and leads visitors down a wooden staircase to a platform 65 feet underground, with a ten-story spiral staircase continuing to a second platform at the chamber's base for those seeking more adventure. The Expedition Tour offers undeveloped caving with climbing and belly crawling through unlit passages while wearing lighted helmets, requiring advance reservations. Above-ground activities include gold panning and axe throwing. Military members and their immediate family receive 10% off Spiral Tour and Expedition Tour reservations. Axe throwing discounts include $5 off a ten-minute single-person session for ages twelve and up. Current deals are available at moaningcaverns.com.
