Dive-site story
Devil's Den is a prehistoric subterranean spring formed by a collapsed karst sinkhole. Sunlight streams through the narrow chimney opening above, illuminating an inverted mushroom-shaped cavern filled with clear spring water. Divers descend a wooden staircase into the chamber to access submerged training platforms, fossil beds, and swim-through channels circling the central debris mound.
