Don't just wander the surface of the earth — have a look at what's underneath it too. See strange natural formations and shapes in the deep, shadowy recesses of Moaning Cavern.
When planning your adventure to Moaning Cavern in Angels Camp, don't forget to set aside money for an entrance fee. Want another tip? When you're done at the natural underground attraction, head to Glory Hole Sports, Columbia State Historic Park and Greenhorn Creek Resort for your next sightseeing adventure.
