The water temp is a constant 22°C/72°F year-round. Devil's Den is a geological formation known as a karst fenster (karst window). The diving area is actually a subterranean river, and the steam that rises through the "window" on cold winter morning is how the dive site got its name. Underwater you'll see a surprising number of curious fish including guppies, crappies, catfish and turtles. Divers can explore swim-throughs and ancient rock formations including fossil beds dating back 33 million years. Animal remains from camels, dire wolves, mastodons, and saber-toothed cats have been discovered here. The crystal clear water is 15 metres/50 feet deep with gorgeous sunbeams streaming in overhead. RV and tent camping is available in addition to four on-site cabins for rent.
