Cave-in-Rock – Haunted Cave in Cave-in-Rock, Illinois

Perched on the banks of the Ohio River, Cave-in-Rock State Park is best known for its eerie namesake—a massive natural cave carved into a limestone bluff. But beyond its scenic beauty lies a dark past.

Once a hideout for ruthless outlaws and river pirates, this cave has soaked up centuries of bloodshed, betrayal, and death. Many believe that the spirits of the murdered still linger in the shadows of the rock walls, whispering stories that were never meant to be told.

Historical Background

• Original Purpose: Natural cave later used by bandits and pirates as a criminal base
• Significant Events:
