Dive-site story
Located near Williston in north-central Florida, Blue Grotto features a freshwater cavern opening from a surface basin into a daylight-lit, bell-shaped chamber. An inverted air bell anchored inside lets divers pause and communicate underwater. Past limestone formations, the steeply sloping floor drops to a delicate silt basin demanding precise buoyancy control.
