Diving Cozumel & the National Marine Park
Cozumel's reefs run for miles along the island's sheltered western shore — a chain of coral walls, canyons and shallow gardens inside a protected marine park, all dived the easy way: drifting with the current.
Why Cozumel
One of the world's great drift-diving destinations
Cozumel sits at the edge of the Mesoamerican Reef, the second-largest reef system on earth. A steady current sweeps along the island's leeward side, carrying clear Caribbean water — often 30m of visibility or more — over a wall that drops into the blue. You don't fight it; you fly with it.
Drift diving
The current does the work. We splash in, hang in the blue, and let the reef glide past — relaxed, efficient, and ideal for long, easy dives.
A protected park
Most sites lie inside the Parque Nacional Arrecifes de Cozumel. Park fees fund the reef's protection and are included on every trip.
Year-round & warm
Water sits around 26–29°C with high visibility most of the year. See when to dive for the seasonal detail.
