Devils Den

Devil's Den is a freshwater spring formed by a collapsed limestone sinkhole in central Florida, creating a compact, prehistoric cavern lit by a central skylight. The site features an inverted mushroom-shaped chamber with steep limestone walls, stalactites, fossil deposits, and several narrow swim-throughs and alcoves. It is widely regarded as one of the most popular and frequently visited freshwater cavern dives in the region. Entry is via an external stairway to a submerged platform at the pool edge (shore entry). Maximum depth is about 50 feet, the chamber ceiling at the entrance is roughly 35 feet above the water, and the cavern expands to about 200 feet across at depth. Water temperature is approximately 72°F year-round, visibility commonly 90–100 feet, and there are virtually no currents. Lights are recommended for exploring deeper corners and divers should maintain good buoyancy to avoid stirring silt. Specific safety rules apply: divers must be certified (Open Water or higher) and dive with a buddy, cave entry beyond the lighted cavern area is prohibited, and the operator enforces equipment restrictions (no double tanks, no rebreathers, no reels). Low ceilings and tight passages present a head-strike risk, and the entry area can be crowded with snorkelers. Basic facilities (restrooms, air fills, dive platforms) are provided on site.
