Famous all over the world for its coral reefs, there are plenty of water sports such as diving, deep-sea fishing, snorkeling, kayaking and more. Cozumel's mostly undeveloped territory at the center of the island is covered by jungle and swampy lagoons, which are home to tiny mammals a endemic birds that have never left the island. Noteworthy is the Chankanaab National Park, a Cozumel icon, and the Punta Sur Ecological Reserve.

This huge protected area at the southern tip of the island includes Punta Celarain and its historical lighthouse, as well as the Colombia Lagoon, a shelter for many of the island's endemic species, as well as other endangered forms of life, such as marine turtles and their nesting areas.
