Deadman's Cays
Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Deadman's Cays offers some of Florida Keys's richest reef diving. Water ranges 19-32°C, warmest July, August, September.
Deadman’s Cays sits off the Lower Keys, a spot we often find ourselves returning to for a reliable reef dive. It’s a series of small coral heads, not a sprawling wall, which means we can spend a good hour exploring the nooks and crannies without feeling rushed. We often spot things like fairy basslets darting into crevices and yellowhead wrasse sifting through the sand. It’s a good choice for a second dive of the day, or if you’re looking for a relaxed pace without battling strong currents.
