Dirt track that ends next to a watering hole for the cattle. Eye! According to a sign, some are brave so it is not advisable to cross the fences. Nice views of the swamp in the distance.

Built in 1972 and belonging to the Isabel II canal, the El Atazar reservoir is the largest in Madrid, housing 46% of the community's impounded water. Located in a rugged enclave full of slate, the landscape that surrounds the reservoir and that is born from its waters is spectacular, giving way to monumental natural routes and walks through its surrounding historic towns.
