Perched like a jewel off the northeastern tip of the Yucatán Peninsula, Isla Contoy is less a resort escape and more a living, breathing ark. A highly protected, uninhabited national park island near Cancún, it reads like a love letter to wild places: a narrow crescent of pale sand, mangrove-scarred lagoons, coral fringing the shore and a looming canopy of tropical birds that make the island one of the most important avian sanctuaries in the Caribbean.

The marine fringe is equally compelling. Clear, shallow waters and nearby coral gardens make for excellent snorkeling from the boat—expect to share the view with rays, reef fish and occasional sea turtles—but remember the island’s strict rules: no collecting, no anchoring on coral and minimal
