Dive Morros de Potosi
A 40 minute boat ride to the southwest of Zihuatanejo Bay brings us to one of the most spectacular diving zones of the Mexican Pacific: Los Morros de Potosi. These large white granite rocks that emerge from the waters are also known at the Frailes Blancos (White Friars). The perfect equilibrium of marine fauna and a great variety of birds including pelicans and seagulls, whose guano gives these rocks their characteristic white color.
The Morros de Potosi are full of fascinating surprises like caves, cliffs, vertical walls, canals and tunnels. As well as coral formations and submarine mountains, a superabundance of different manifestations of aquatic life are found here.
Because of the strong currents this site is recommended only for experienced divers, though there are protected areas where snorkeling is possible.
El Bajo de Afuera is well known for its great beauty. Swim through arches, glens and vertical walls
North of the Morros, in Caleta Norte (North Cove), there is an area protected from the currents where you can snorkel close to the cliffs, ideal for passing surface time between dives. To the south of the Morros, you may dive the Cave of Gertrudis, which was once inhabited by a cat shark by the same name. A special course in cave diving is recommended before exploring undersea caverns. In front of the shark’s cave are other equally interesting sights.
