Devils Den Prehistoric Spring

Bought in 1993 by our current owners, this natural wonder has been transformed from a simple scuba diving site to a world class tourist attraction.
Visit one of North America's most prehistoric places, Devil's Den Spring!
This underground spring inside a dry cave has been home to many extinct animal fossils dating back to the Pleistocene Age, which are on display at The University of Florida's Museum of Natural History.


's Den Spring:

  • 120 ft. surface diameter

  • 72 degrees F/22.2 degrees C year round water temperature

  • Inverted mushroom shape below the surface

  • Maximum depth is 54 ft/16.45 m


Blue Grotto Spring

The dive begins at the mouth of the cavern, which is 80ft wide and 20ft high.

Look from topside into the sharp blue of the pool and you will understand why Blue Grotto is well known for its exceptional visibility year round.

30ft below the surface is the only air bell available to spring divers in the region, filled with fresh compressed air that allows you a unique opportunity to stop and talk with your buddy under the water.

Descending from there, at 50ft a permanent guideline brings you to the crescent shaped cavern where you will experience an array of fossils along the walls of the camber and an abundance of aquatic life waiting for a free handout.

But words will not do justice to the experience of diving in this secret underwater hideaway. Come dive for yourself!
