Overview
Cozumel, the largest inhabited island in the Mexican Caribbean, sits atop the Mesoamerican Barrier Reef — the second-largest coral reef system on Earth. Its western shore offers world-class snorkeling in protected marine parks with 30+ metre visibility.
Highlights
- Palancar Reef: Towering coral pillars and swim-through canyons teeming with angelfish, moray eels, and sea turtles.
- Colombia Reef: A deep-water site with enormous coral formations and frequent eagle ray sightings.
- El Cielo Sandbar: A waist-deep area nicknamed "Heaven" where hundreds of starfish rest on white sand.
History
Jacques Cousteau's 1961 television documentary on Cozumel's reefs brought the island to global attention. The establishment of the Cozumel Reefs National Marine Park in 1996 protects 120 km² of marine habitat.
Visitor Tips
- Take the ferry from Playa del Carmen: 45-minute crossing; Cancún transfers also available.
- Use a snorkel boat tour: Reef sites are offshore and require boat access for the best spots.
- Duration: Full day (6 hours including ferry transit from Cancún).
