| Ash Cave is the largest recess cave east of the Mississippi and perhaps the most awe-inspiring feature of Hocking Hills State Park. With a horseshoe-shaped rim that spans 700 feet, with a runoff waterfall, Ash Cave is enormous and open on one side. It’s the southernmost of six natural areas that comprise Hocking Hills State Park, and is a must see for all visitors looking to experience Ohio caves. | |
