Portopetro is a small coastal town in the southeastern municipality of Santanyi. It is made up of traditional low-rise homes with tiled rooves and Mallorcan shutters. Along the waterfront, cafes and restaurants overlook a lovely marina and the Real Club Nautico (Portopetro´s Yacht Club). There are two sandy bays within a short walk of each other and to the south is the Mondrago Nature Reserve with its hiking trails and stunning bays of Cala Mondrago and Cala S´Amarador.
