Wonderful day spent yesterday at Praia das Rocas. One of the best places I've been to in Portugal! The River Beach of Rocas is a leisure complex with animation and fun set in a lake with nearly 1 km long, right in the heart of Castanheira de Pera . It consists of an island in the centre of the beach , a wave pool with 2100 m2 ( the largest in the country) , a reservoir and a secular bridge constitute an environment where dreams and reality merge . The clear waters of Ribeira de Pera overflow , forming a charm where tropical palms coexist harmoniously with the Serra da Lousã peering from above . You can also enjoy yourself in rowboat or pedal boat. You can also do abseiling and stay overnight in one of the six bungalows on the shore of the reservoir , with a privileged view of the huge mirror of water.
