Cave-in-Rock State Park, State park and cave system in Hardin County, United States
Cave-in-Rock State Park encompasses a natural limestone cave system situated along the Ohio River. The cave was shaped by water flow and geological forces across millennia, featuring multiple entrances and interconnected chambers.
French explorers documented the cave in the early 1700s, and it later became notorious as a hideout for river pirates. This phase of lawlessness faded as settlement increased and law enforcement reached the region.
The cave served as a refuge for river criminals for many years before becoming a gathering place for the local community. Visitors can still sense this layered past as they move through the natural chambers.
The park offers walking trails of varying difficulty with views toward the river and surrounding woodland. Wear sturdy footwear and be aware that the cave interior remains cool and can be slippery in places.
A striking natural opening at the top of the cave allows daylight to filter through, creating changing effects as the sun moves. This vertical passage reveals how the cave was sculpted by water and stone over deep time.
