Marquesas Keys Wildlife Management Area
Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Marquesas offers some of Florida Keys's richest diving. Water ranges 19-32°C, warmest July, August, September.
The Marquesas are a ring of low-lying islands, and the diving here is often quite calm, great for beginners. Depths typically run to 20m, making it a good spot for longer bottom times. You’ll find a mix of smaller reef fish cruising the sandy bottoms and some scattered coral patches. It’s a solid choice if you're looking for a relaxed dive away from the Keys’ busier sites.
