Site details

Blue Hole (Jug) Spring is the only divable site in Ichetucknee Springs State Park and the largest spring on the Ichetucknee River. A short swim across the shallow basin leads to a cave entrance about 40 ft down, with nearly 600 ft of mapped passage beyond. The park permits cavern- and cave-certified divers only — no open water diving — with mandatory registration at the North Ranger Station and a half-mile trail carry to the water.

Strong outflow at the vent, silting in passages, half-mile gear carry, manatees seasonally present (keep 50 ft distance). No open water diving permitted; minimum two-diver teams; dives must end one hour before sunset.
