Cozumel: Flight time from Houston 2 hrs 20 minsAlthough Cozumel attracts hordes of tourists, the bliss divers will find below the surface makes braving the topside crowds well worth it. With visibility often surpassing 100 feet, Cozumel’s western shore offers insane reef diving. The steady current flowing through the Yucatan Channel delivers a rich stream of nutrients to the abundant coral, sponge and fish life. And at dive sites like Palancar and Tormentos, you’ll see nearly every reef fish on the ID cards —from spotted morays and schooling French grunts to rock beauties and queen angels. Add canyons, pinnacles and steep walls to the mix, and it’s no surprise that Cozumel is consistently listed among the world’s top dive destinations.
