Troy Spring
Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Troy Spring offers some of Florida Keys's richest cave diving. Water ranges 19-32°C, warmest July, August, September.
Troy Spring offers a unique freshwater diving experience in the Florida Keys. Divers can explore the remains of a 19th-century steamboat wreck, which sits among cypress knees and limestone formations. The spring is home to a mix of freshwater species, including various killifish and mollies, with occasional tarpon sightings. It’s a good spot for divers looking for something different from typical Keys reef dives, particularly those interested in history and spring environments.
