    StandoutExceptional marine biodiversity

    Cozumel diving, for us, means two things: drift and drift. That current is often cranking, pulling you along massive coral structures, sometimes at a clip. Don't fight it, just relax and enjoy the ride. We love how the wall dives here, even at just 19 metres, feel much deeper because of the sheer drop-offs and incredible visibility. Keep an eye out for the Cozumel Splendid Toadfish; it's an odd, colourful little bottom dweller we always enjoy spotting. You'll find them tucked under ledges. The reefs are healthy, with impressive Elkhorn and Ridged Cactus Corals providing cover for lots of smaller reef fish – think Clown Wrasse zipping past, and Pearl Blennies peering out from their holes. We’ve drifted past Spotted Eagle Rays gliding by, and Nurse Sharks dozing under overhangs. It’s perfect for divers who appreciate a good drift and don't mind a bit of speed, letting the ocean do the work.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
