By far the most popular place to snorkel is El Garrafón Natural Park. It is at the southern end of the island, where you'll see numerous schools of colorful fish. The pricy but well-equipped park has two restaurant-bars, beach chairs, a swimming pool, kayaks, changing rooms, rental lockers, showers, a gift shop, and snack bars. Once a public national underwater park, Garrafón, since late 1999, has been operated by the same people who manage Xcaret, south of Cancún. Public facilities have been vastly improved, with new attractions and facilities added each year. Activities at the park include snorkeling and "Snuba" (a tankless version of scuba diving, when you descend while breathing through a long air tube), crystal-clear canoes for viewing underwater life.
