Praia da Rocha or Rock Beach is a beach and built up area on the Atlantic Ocean in the southern section of the concelho of Portimão, Algarve, southern Portugal.
Nearby Praia dos Três Castelos beach is well known for the bizarre and dramatic limestone rock formations that stand along the water. In some places, the cliffs are sheer and drop straight down to the beach, but in others, erosion has left fanciful shapes likened to castles or pyramids.
The beach soccer tournament, Mundialito de Futebol de Praia, which hosts some of the world's best national teams, took place here annually from 2005 to 2012. Algarve Tourism lists a number of attractions in the region (including marine and waterparks), as well as the area's restaurants and bars, nightlife and marina complex.
