Cave-in-Rock State Park
Cave-in-Rock State Park sits atop dramatic 160-foot limestone bluffs overlooking the Ohio River in Hardin County, Illinois. Dominated by a massive 55-foot-wide natural cave carved into the limestone cliff face, the site possesses a bloody history as a 18th and early 19th-century stronghold for river pirates, highwaymen, counterfeiters, and outlaws who preyed upon frontier flatboat travelers. Today, visitors report ghostly apparitions, disembodied cries echoing from the cave interior, and eerie unseen presences.
