The Cozumel reef system is part of the Mesoamerican Barrier Reef System, the second largest coral reef system in the world. The reef system spans almost 175 miles (280 km) of ocean between the Gulf of Mexico and Honduras. Cozumel’s spectacular reef formations, effortless drift diving and exceptionally clear waters make this island one of the world’s most popular diving destinations.
In 1996 the Mexican government declared the reefs of Cozumel a National Marine Park. Even though almost the entire island of is surrounded by coral reefs, the park includes shoreline and reefs starting just south of the International Pier and continues down and around Punta Sur and up just a small portion of the east side of the island . As a result there are currently limits on the number of boats and scuba diving operators allowed on the reefs. Each diver must pay a $2.00 per day park entrance fee which goes towards enforcing the rules.

As our guest you can help us to preserve the reef and marine wildlife:

Corals are fragile
Control your buoyancy – Kicking, touching, dragging your gear causes damage to healthy coral. Photographers in particular, take pictures without causing damage. Do not grab the coral and leave your gloves in your BCD pocket during the dive as they are not allowed to be used in the marine park.

Marine organisms are protected by law
Fishing, feeding the fauna and taking souvenirs is against the law.  Refrain from extracting or annoying the marine flora and fauna.

Help us prevent pollution
Use biodegradable sun block products. Report fuel, oil, sewage and garbage spills to the National Park office.
