Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Cannon Patch offers some of Florida Keys's richest reef diving. Water ranges 19-32°C, warmest July, August, September.
Cannon Patch, found in the Florida Keys, holds true to its name with a scatter of old cannons on the seafloor. It's an easy dive, often shallow, where divers can spend time poking around the historical artifacts. We often spot nurse sharks tucked under ledges and plenty of grunts schooling around the patches of coral. It's a relaxed spot, good for newer divers or those looking for a leisurely second dive.
