There are a few places in the world that promise unique experiences for lovers of diving, snorkeling, and marine life, and one of them is on the Caribbean coasts of Mexico, Belize, Guatemala and Honduras: the magnificent Mesoamerican Barrier Reef System.
The Mesoamerican Reef is the second largest reef in the world (after the Great Barrier Reef in Australia) and the largest in the Western Hemisphere, extending approximately 625 miles (1,000 kilometers) from the Yucatan Peninsula in Mexico to the Bay Islands on the northern coast of Honduras.
Throughout this reef system are vast expanses of coastal wetlands, seagrass pastures, lagoons, mangrove forests, beaches, and dunes. These ecosystems are home to a rich biodiversity that includes 65 species of stony corals, 350 species of mollusks, more than 500 species of fish, and one of the largest manatee populations in the world. In addition, on the reef and in its surroundings live many endangered species such as leatherback sea turtles, West Indian manatees, black coral, and marine crocodiles, and seasonally it is also home to the largest aggregation of whale sharks worldwide.
This rich biodiversity and the beauty of the landscapes created by the reef's ecosystems make it a great tourist attraction. An estimated one in five people living on Caribbean coastlines is employed in tourism, an industry that is among the primary sources of income in these countries.
For starters, travelers can enjoy beautiful, fine white sand beaches that are products of the disintegrated remains of corals, calcareous algae, and other reef organisms. Tourists can also explore the coastal wetlands and mangroves of this reef, which serve as the nursery for many species of fish and provide an excellent opportunity to observe wildlife on canoeing and kayaking excursions.
However, scuba diving is the way that tourists can best experience the reef in all of its splendor. The warm, shallow, crystal clear waters of the coast bordering the Mesoamerican Reef offer impressive visibility of the hundreds of multicolored fish, turtles, manatees, and other marine species, as well as many types of coral.
Cancun, the Riviera Maya, and Costa Maya are some of Mexico's most popular sites for diving. In Belize, the biggest attraction is the Blue Hole; considered one of the top 10 dive sites in the world, it is located in Lighthouse Atoll and consists of a system of underwater caves and passages with stalactite formations dating to the last ice age. On the Caribbean side of Guatemala, the port of Livingston is popular for diving directly offshore and in the nearby Belize Cays. Finally, Honduras boasts sites such as Tela, Cayos Cochinos, Puerto Cortes and the Bay Islands (Roatán, Guanaja and Utila).
Sadly, the Mesoamerican Reef faces major threats caused by pollution, over exploitation of resources, and uncontrolled coastal development, among others. For this reason, and because of its immense importance for wildlife and the economy, the countries near the reef have created several national parks and protected areas to help conserve it. Some of these are Cozumel Reefs National Park, the Belize Barrier Reef, Hol Chan Marine Reserve, the Sian Ka'an Biosphere Reserve, and the Cayos Cochinos Marine Park.
Similarly, initiatives such as the Mesoamerican Reef Tourism Initiative (MARTI) and several community projects aim to implement best sustainable tourism practices to reduce the negative impact of tourism activities on the wonderful Mesoamerican Reef.
