The last time I went was in 2000, and it's just a hole in the ground, it's about 100' deep, and bell shape, it's narrow at the top and then gets wider as you go deeper. This is feed by an underground spring; the opening from the springs goes into a cave system, and good luck on trying to dive it. The dive spot is fenced in, and the cave system, is bared, and lock. This is a hot scuba park for OW and AOW classes, and it crowded on the weekends, and there is only one entry into the dive spot. For someone to take a trip, and travel 12 hours to dive this place is not worth it, go somewhere else.
