Blue Grotto is the spring side of an inline sinkhole with three distinct areas for divers to explore.
- To start, there is a large open-water basin with depths to 40ft. Three platforms make this perfect for diver training. Divers will find lots of curious fish and the Grotto's favorite resident, Virgil the Turtle (who is acutally a girl). Virgil is amazingly friendly and will approach divers and sniff their fingers looking for a handout.
- The large upper cavern has a wide entrance and offers depths to 50ft. Near the entrance is an air bell with viewing windows and breathable air pumped from the surface. There are interesting artifacts spread throughout the cavern.
- The lower chamber has no ambient light and offers no direct sight of the entrance. In this environment, highly specialized training (Advanced Open Water) and equipment (Lights & ) are essential. It is not for recreational divers using standard scuba gear.
