Devil's Den is a natural Florida phenomenon. A large dry cave that extends down about 60 feet to the waterline.
Scuba divers will enjoy this rarity as they swim through ancient history. From the water line you enter a sinkhole with many caverns and crevices to explore. Depths reach 65 feet and visibility is dependant upon the number of divers in the pool that day.
Always check with owners to ensure they are open before you drive and for current pricing.
