The story

Ash Cave was formed like the region's other recess caves: the middle layer of Blackhand sandstone weathered and eroded, while the harder upper and lower layers stayed intact. The trail approaches through a narrow gorge lined with hemlock and beech that opens suddenly onto the great overhang, and a small stream drops over the rim into a plunge pool.

It is named for a huge pile of ashes early settlers found under the shelter, recorded as 100 feet long, 30 feet wide and 3 feet deep. The source is unknown, but the ashes are widely believed to be from Native American campfires built up over hundreds of years, and some accounts say the fires were used for smelting or making saltpeter, though that is a guess. Like Old Man's Cave and Rock Bridge, it was already a big attraction by the late 1800s, and Civilian Conservation Corps workers of Company 526 improved several Hocking Hills sites in the 1930s.

A recess cave is an open alcove; it is not an underground cavern. Trail closures happen, so check ODNR before you go.

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.
