Before being a reservoir it was a valley between mountains with villages on the banks that are now covered by the waters. There is something that always stands out on the surface and is the tower and bell tower of the church. Now the crystalline and pure waters of the Cinca, Ara and other rivers, are dammed and allow us to navigate through them and their unique places in solitude appreciating its mountains reflected in the water, its fauna and birds such as eagles, kites, vultures, hawks, seagulls, bonebreakers, etc.
