Beginners and experts alike can explore the sea at dive sites like Santa Rosa Wall—which is teeming with turtles, lobster and gigantic grouper--and Palancar and Columbia reefs. On land, Discover Mexico Cozumel Park offers guided tours on aspects of Mayan culture. Favorites include the Jose Cuervo Tequila and chocolate-making exhibition. At Chankanaab Beach Adventure Park, visitors can swim with dolphins or take in a sea lion show. By ferry, Playa Del Carmen and the Cancun mainland is just an hour away.
Whether arriving via Cozumel International Airport (CZM) or one of the many cruise ships that stop on the island, you'll first want to hire one of the 750 taxis on the island.

For a secluded beach experience head to windward beach and spots like Coconuts bar, which provides unparalleled views atop Cozumel's only cliff.
