Devil’s Den Prehistoric Spring

Devil’s Den – Williston, FL

Devil’s Den Prehistoric Spring is a unique little spot in Williston, FL. The underground spring is formed by a karst window. It is home to extinct animal fossils dating back 33 million years. The water is crystal clear with maximum depth of 54 feet/16.45 meters. Much like Blue Grotto, the water is a constant 72 degrees Fahrenheit.

The name “Devil’s Den” was given by early settlers – not because of spooky things lurking below the surface, but from cold winter mornings where you can see smoke-like steam rising from the chimney opening.  Newbie divers looking to obtain Open Water certification regularly use this privately owned and operated training and recreational facility. You can opt for snorkeling if diving isn’t your jam.
