Devil’s Den Scuba Diving
Descend into a prehistoric underground spring with clear, 72°F water, a dramatic skylight, training platforms, and a maximum depth of 54 feet.
What makes Devil’s Den different
Devil’s Den is a privately operated spring inside a dry cave. Divers enter through a narrow surface passage and descend stairs to the platform below, where sunlight pours through the opening above the blue water.
The spring is roughly 120 feet across at the surface and widens below in an inverted-mushroom shape. Fossils discovered here connect the site to Florida’s prehistoric past, but visitors must leave all rocks and fossils untouched.
From the surface entrance to 54 feet
The unusual access and overhead rock make a careful buddy plan more important than at a typical open-water spring.
Stairway Access
Carry equipment down the enclosed stairway carefully and use the platform to organize your entry and exit.
Open Spring Basin
Explore the approved basin beneath the natural skylight while maintaining awareness of other divers, snorkelers, and the platform.
Rock Formations
The spring broadens below the surface, with ledges and formations visible along the permitted route. Maximum depth is 54 feet.
72°F water throughout the year
Devil’s Den reports a steady water temperature of 72°F (about 22°C). A full wetsuit is a practical starting point for many divers, although the right exposure protection depends on your cold tolerance and planned bottom time.
Bring a light for color and detail beneath the rock ceiling, but do not use it to enter prohibited cave passages.
