Jackson Blue Spring

Jackson Blue Spring is probably one of the most beautiful landscapes and cave diving spots in North Florida. The cave itself is no less spectacular. With depths ranging in the 100 ft, visibility in the 100 ft range, and cave passage that runs between 4,000 and 6,000 ft in linear distance, this cave rocks! Flow has been minimal for several years now, but when the Floridian aquifer is charged up with heavy rains, this cave can blow! The open water basin is 20 ft deep. The park is owned by the county and is open during the summer for swimmers. The cavern area (within daylight zone) is spectacular. Lots of crawfish hid in rock crevices. You can go 200 ft inside and still be in the cavern zone. It's a huge room full of large boulders that have fallen from the ceiling many years ago. The cave itself is primarily rocky, but there are a number of side passages further into the system that can get very silty. The cave doesn't really begin branching off into many conduits till at least 1,400 ft upstream. Prior to that, it was mostly one straight tunnel.
You must first check in at the Jackson County sheriff's department to get in. Diving fees are $25/person/day. The dive site is available 24/7. They allow night, open water, cavern, cave, solo, and scooter/DPV diving. Cave diving can be a deceptively easy way to die. Dive within your level of training and equipment. Do not enter a cave unless trained to do so.
