Why is Cozumel considered a world reference for diving?
Diving in Cozumel attracts divers from around the world every year thanks to exceptional biodiversity, visible from the first meters underwater.

Diving here means observing bull sharks, turtles, angelfish, moray eels, and rare creatures like the endemic toadfish.
Drift diving on this island allows divers of all levels to explore reefs, drop-offs, and coral gardens. Optimal underwater conditions, with visibility ranging from 30 to 40 meters and a stable water temperature between 26°C and 30°C, make the experience unique all year round. Exemplary environmental management includes seasonal site closures to allow natural reef regeneration.
