Cozumel is geologically similar to the Yucatán, with its interior consisting in a plain broken by low hills that are only about 50 feet (15 metres) above sea level. Much of the island is covered by scrubby tropical jungle.
Clear, warm water, spectacular coral reefs, and abundant marine life make Cozumel one of the world’s best scuba-diving destinations as well as a major resort. In addition to the diving opportunities, other water sports, and fishing, tourists are attracted by Cozumel’s tropical climate, sand beaches, and duty-free port shopping, along with its atmosphere, which is more relaxed than that of nearby Cancún. Cozumel has regular ferry service from Playa del Carmen and Puerto Morelos besides of an international airport located only 2 miles (3 km) south of the island centre.
