Cozumel’s reefs are part of the Mesoamerican Barrier Reef System, the second-largest reef system in the world. This fragile ecosystem is protected under the Cozumel Reefs National Marine Park, a UNESCO Biosphere Reserve. Dive operators, like DIMI Scuba Tours, who hold official permits are not just businesses—they are stewards of this sanctuary.
