Caves & Caverns
12 places to go underground or under a ledge
Show caverns, recess caves, rock shelters and sandstone passages
Ohio has about 150 known caverns, but only a handful are open for tours, and many of the state's most famous 'caves' are something else. A true cavern is dissolved out of limestone and lies underground; a recess cave, like Ash Cave, is an open alcove weathered into sandstone. This guide keeps the two apart so you know what you are visiting, and lists only places open to the public.
Stay on the marked trails and official tours. Caves are fragile and can be dangerous, and entering any cave or crevice that is closed, unmarked or not open to the public is unsafe and unauthorized. Where a place has a construction or closure alert, check current conditions before you go.
Underground caves you tour with a guide or an audio tour. These are true caves dissolved out of limestone, or crystal-lined geode caves.
