Roca Partida, Islet in Manzanillo, Mexico

Roca Partida is a small islet in Manzanillo, Mexico, part of the Revillagigedo Islands. It is only 100 metres long and 8 metres wide, with two peaks, the higher one reaching 34 metres.

Roca Partida is part of the Revillagigedo Islands, which were formed by volcanic activity. Unlike San Benedicto and Socorro, it has had no recent eruptions.

The islet is known among divers for its clear waters and marine life, and local dive guides often include it in their routes. Its name, meaning "split rock," comes from the two peaks that form the islet.

To visit Roca Partida, you need a permit from the Mexican Armed Forces because it is a military zone. Divers should arrange permits in advance and check sea conditions, as the area is remote and has no facilities.

The islet has no land plants or animals because there is no fresh water. However, many seabirds, including the Nazca booby and sooty tern, breed on the rock.
