Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Crater offers some of Florida Keys's richest diving. Water ranges 19-32°C, warmest July, August, September.
The Crater is a straightforward dive in the Florida Keys, dropping to 19 meters. It’s essentially a large, sandy depression in the seabed, ringed by scattered coral heads. We usually find smaller reef fish sheltering among these corals, and occasionally a curious nurse shark cruises by. It's a relaxed spot, good for beginner divers looking for an easy descent and a gentle introduction to the local reef environment.
