Board the Carnival Triumph departing New Orleans and hop off in Cozumel for a jeep tour of the jungle or take a horseback ride with a local guide. You can also rent dune buggies, motorcycles, scooters or segways and explore on your own. For nature lovers, swim with stingrays and manatees, take a cave tour or go on a helmet dive just like a Cousteau (who first made this former unknown fishing village popular in the 1960s).
