These coral reefs mainly comprise numerous soft and hard corals and provide a home to various Caribbean fish as well as different invertebrates like sponges, zoanthids, mollusks, crustaceans, and echinoderms. A major portion of the reef that is located in the island’s southern part is under the protection of the Parque Nacional Arrecifes de Cozumel. Together with the Manglares y Humedales del Norte de Isla Cozumel, this park is also protected as a Ramsar site under the Ramsar Wetland Convention. To protect the island’s beautiful coral reefs and its rich marine life, the National Marine Park of Cozumel Reefs was created by the Government of Mexico in 1996.

Brief History

Mayan ruins on Cozumel, Mexico. 

Archaeological studies have revealed that Cozumel was first inhabited by the Mayans from about 300 to 1500 CE. It was regarded as a sacred place for the goddess Ixchel, who was the Mayan goddess of fertility. The Mayans hence named the island Cuzamil Pectin ("The Land of the Swallows”) in honor of the goddess’ favorite bird.

In 1518, the Spanish conquistador Juan de Grijalva led the first Spanish expedition to the island. The Spanish explorer Hernán Cortés also visited the island in 1519. The European expedition to the island brought diseases like smallpox with them, which resulted in the complete devastation of the Indigenous Mayan population. In the following years, the island served as an important hideout for pirates. During the Caste War of Yucatán, which ended the centuries-long war between the Mexican Indigenous peoples and Spanish conquistadors, some refugees settled on the island. The Government of Mexico officially recognized the town of San Miguel de Cozumel in 1849.

The economy of Cozumel is dependent on tourism and the island’s spectacular coral reefs, tropical climate, clear waters, sand beaches, and rich and diverse marine life serve as major tourist attractions. There are several resort areas on the island and the visitors to the island enjoy various recreational activities like scuba diving, snorkeling, para-sailing, kitesurfing, etc.
