Vortex Spring
Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Vortex Spring offers some of Florida Keys's richest cave diving. Water ranges 19-32°C, warmest July, August, September.
Vortex Spring is a freshwater spring system in Florida, offering distinct diving from the Keys. The main basin leads into a cavern system, suitable for certified cavern and cave divers. You'll primarily encounter freshwater species like mosquitofish and American eels, a different experience than saltwater reefs. It's a good spot for divers looking to refine skills or explore overhead environments.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
