What is Devil’s Den?

Devil’s Den is a breathtaking underground spring in Central Florida. Scientifically, Devil’s Den is a karst window. At some point in the past, the land above the subterranean river collapsed. We can now see into the earth below.

The sinkhole that forms Devil’s Den features a constant water temperature of 72 degrees. It is reaches a maximum depth of 54 feet deep and 120 feet across.

It has been privately owned and operated as an attraction since the 1990’s.

Why is it Called Devil’s Den?

On cold winter mornings, steam rises from the underground spring through the hole in the ground. This could be why early settlers named it Devil’s Den.

What Will You See Inside Devil’s Den?

As a snorkeler, we were able to check out ancient rock formations of the spring through the crystal clear water and watch scuba divers explore below us. There were a number of fish congregating under the dock to see, as well as Nelson – the resident turtle.

After swimming and snorkeling for about an hour, we felt as if we had seen it all and were ready to head out.

Fun Fact: There are caves connected to the sinkhole, but they cannot be accessed. However, animal and human remains have been found in the cave system. The fossils date back to the Pleistocene age and have included mastodons, horses, bears, and cats – along with other prehistoric artifacts.
