Coral reef Cozumel: Fascinating for divers and snorkelers

The Cozumel reef is part of the Mesoamerican Reef, the second largest reef system on earth after the Great Barrier reef. It is located in the Atlantic Ocean and begins north of Yukatan, at Contoi island. From there it covers the entire coast of the southeast of Mexico, Belize and Guatemala down to the Bay of islands in Honduras. The Mesoamerican Reef is over 600 miles long and also called ‘Great Mayan Reef’. Thereby it consists of a system of atolls, reefs, lagoonsand seagrass meadows.

Various national parks protect areas of the Great Mayan Reef. The Arrecifes de Cozumel National Park takes care of various projects around the Cozumel reef. Because the Cozumel reef surround almost the whole island and the government of Cozumel tries to protect it against possible threats. Thereby the reef of Cozumel stretches parallel to the island and can easily  be reached by boat.

Cozumel is considered one of the best diving and snorkeling areas in the world. Already Jacques Cousteau discovered on his dives in the sixties the beauty of the coral reefs on Cozumel. Since then, thousands of water sports enthusiasts come every year to dive at the fabulous Cozumel reefs or discover the underwater world of Cozumel on a snorkeling tour.

In the very south of Cozumel island is the famous Devil’s Throat andPunta Sur. The ‘Garganta del Diablo’ (Spanish for Devil’s Throat) is adramatic tunnel that lies between 115 and 90 feet. Because of the depth and the caves this dive is only suitable for divers with very good buoyancy and controlled air consumption. Only take experienced should go for this challenging dive.

Part of the southen Cozumel reef is also the ‘Cathedral’, a spectacular ‘room’, surrounded by corals.The name comes from the elongated windows in the corals which remind of a cathedral. Because of the depth, those both dives in the south can not be combined. Therefore we will dive either Devil’s Throat or Punta Sur.

The very famous, more than 1,5 miles long Palancar reef consists of various dive sites. Many 2 tank excursions start their first dive in the Palancar reef on Cozumel. Because the currents are less strong than further south. Well known are the dive sites Palancar Bricks, Palancar Caves, Palancar Horseshoe, Palancar Gardens, Francesa and Dalila. All those Cozumel reefs are completely different. This demonstrates how large and divere this area is. While in Palancar Caves has beautifulcaves and swimthroughts, in Palancar Gardens and Francesa are magnificent tunnel systems under the reef.

Like most of the reefs on Cozumel, Paso de Cedral has a wall and a little bit further towards the island is the actual reef. Both parts are completely stunning but totally different. Many divemasters combine both dive sites. Paso de Cedral is one of the most popular dive sites in Cozumel. And for a reason: Especially the green turtles excite many divers. Closed to the wall is one of the main turtle feeding area of the Cozumel reef. The turtles are accompanied by angel fishs that also feed from the loose coral pieces. The nurse sharkand the green moray eal you see in the picture live right at the end of Paso de Cedral under an overhanging rock. With some luck both can be seen at the same time.

The Santa Rosa reef on Cozumel also has a wall and a shallow reef. One of the main attractions of the wall arefascinating cave formations in the steep slope. Santa Rosa reef is a shallow and easy to dive. It is just perfect forbeginning divers and snorkelers.
