Devil’s Eye Spring issues into a spring pool 60 ft (18.3 m) by 30 ft (9.1 m).
The vent is a 20 ft (6.1 m) in diameter and 27.4 ft (8.4 m) deep, vertical shaft in the center of the spring pool. The pool bottom is sand with exposed limestone and aquatic vegetation. The clear blue water flowing out of the vent produces a prominent boil on the water’s surface. The conduit system is connected with Devil’s Ear Spring 50 ft (15.2 m) to the north. The spring run from Little Devil, whose pool is 250 ft (76.2 m) to the southwest, flows over Devil’s Eye Spring and enters the Santa Fe River from the south. The area surrounding the pool is forested with cypress and oak trees. Wooden stairs enter the water on the east and west sides of the spring pool. The Santa Fe River flows past Devil’s Eye Spring 50 ft (15.2 m) to the northwest. The spring is located within Ginnie Springs Outdoors, a private campground and outdoor recreation concession. The cave system is a popular dive destination with over 30,000 ft (9,144 m) of mapped passageway. Discharge on November 4, 1997 measured 41.48 ft3/s(4).
High flow. Visibility can be excellent if conditions are right. Because of high flow, pull and glide techniques are used at the front. Great cave for scootering. Use of Nitrox is preferred due to decompression obligations. Due to the many places to see, there is a lot of diving just in that cave system alone.
