Cozumel has ranked for years among the top five dive destinations in the world. Tall reefs line the southwest coast, creating towering walls that offer divers a fairy-tale landscape to explore. For nondivers, it has the beautiful water of the Caribbean with all the accompanying watersports and seaside activities.
The island of Cozumel gets a lot more visitors from North America than Europe for reasons that probably have to do with the limited flights. It is in many ways more "cozy and mellow" than the mainland no big highways, no big construction projects. It's dependable. And one of my favorite things about this island is that the water on the protected side (western shore) is as calm as an aquarium, unless a northern wind is blowing. The island is 45km (28 miles) long and 18km (11 miles) wide, and lies 19km (12 miles) from the mainland. Most of the terrain is flat and enveloped in a low tropical forest.
