Views of the Lozoya River

Highlight • Viewpoint

The Lozoya is an important tributary of the Jarama along whose 91 kilometer route six reservoirs have been built. Right at this point, the valley takes the shape of a canyon due to its proximity to the El Villar reservoir, where the course of the river narrows to a great extent.

El Atazar Reservoir

Highlight • Lake

Built in 1972 and belonging to the Isabel II canal, the El Atazar reservoir is the largest in Madrid, representing 46% of the community's embalmed 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 historical towns.
