Cozumel

The Mexican Caribbean island of Cozumel is a frequent stop for cruise ships because of its excellent scuba diving. Divers can explore the underwater sculptures at the Museo Subacu√°tico de Arte and the Mesoamerican Reef in Arrecifes de Cozumel National Park. There are dolphins, manatees, and sea turtles in the waters of Chankanaab, an environmental park that features a lagoon with underwater tunnels.
