The largest inhabited island in Mexico, Cozumel gained worldwide acclaim when legendary scuba diver Jacques Cousteau heralded its coral reefs in 1959 as some of the world’s finest. Diving remains Cozumel’s primary draw, but you’ll also find an abundance of Mayan culture, white-sand beaches and interesting neighborhoods. Visit the World Heritage-listed and remarkably preserved ruins of Chichen Itza, a sacred Mayan center for centuries. Trek through the jungle mangroves and Mayan ruins of the Faro Celerain Ecological Reserve on Cozumel’s southern tip. Shop for local crafts, jewelry, Mayan replicas, cigars and tequila along the waterfront avenue of Rafael Melgar and main square of Plaza del Sol.
