Cabo Pulmo National Marine Park has been described as the most successful marine reserve in the world.

Located 96km (60 miles) north of Los Cabos (2hrs driving from Cabo San Lucas) the park stretches eight kilometres (five miles) from Pulmo Point south to Los Frailes.

It’s one of the most important areas of the Sea of Cortez region. This importance lies in the large number of marine species that inhabit the place and the fact that is the only living coral reef in the northernmost part of the American continent, it is the only hard reef in the entire Baja California peninsula And it's also one of only three remaining living reefs in all of North America.

In 2005 Cabo Pulmo was named a UNESCO World Heritage Site, and in 2008 it became a Ramsar International Wetlands site.

But although conservationists could see the effect on marine diversity and populations, it was not until the results of an extensive study were released in 2011 that the true success of the marine park became apparent.

In 2011 Mexican scientists revealed that over a period of ten years fish populations recorded in Cabo Pulmo had increased dramatically – fish biomass had increased by 463 per cent. Top predators such as sharks also returned in numbers, as did schooling fish and a whole plethora of marine life.

The Cabo Pulmo Reef has eight fingers of hard coral reef, which provide a safe haven for many of the 800 species of marine animals found throughout the Sea of Cortez.
