The Devil’s Caves system in Ginnie Springs, off the coast of Gainesville in Florida, is one of the most dangerous caves in the world to explore. The system has three separate springs, Little Devil, Devil’s Ear, and Devil’s Eye. Devil’s Ear is a canyon-like opening at the junction of the Sante Fe River and Devil Spring.the caves have a strict “no-lights” rule, and only certified cave and cavern divers can enter the system while carrying lights.
