Moaning Caverns is home to the largest single cave chamber in California. With a 20 to 30-foot thick ceiling, the open area inside the chamber is, in fact, tall enough to hold the Statue of Liberty (pedestal excluded)! The massive room extends into the marble deposit of the Calaveras Formation over 180 feet before funneling into smaller passageways. Visitors may view the cavern’s main chamber by walking and climbing the staircase to a flat platform 65 feet underground. For the truly athletic and adventurous, from there, a ten-story spiral staircase leads down to a second platform at the base of the chamber. This unique 100-foot high spiral staircase is an architectural wonder and was built in 1922 using scrap metal from an old WWI battleship!
