On this right slope of La Sierra Cebollera there is a forest track that can be seen on the map. Well, further up and down the track there are many springs that correspond to the Sources of the Jarama River. The land constitutes a triangle, in the shape of a funnel where the Sources of the Jarama River are distributed. The most appropriate time to visit them is during thaws or in spring. Logically, in summer many of them stop flowing.
