It is the largest reservoir in Madrid. There is a viewpoint that is at a height above the wall of the dam from where you can see the development of the reservoir and its tail.

A very well preserved dam, it is currently the oldest working dam in the entire region. The views down from the bridge across it or up the stairs from the top are amazing. It is very worth it. Just down the road is a lovely picnic spot with benches under the pine trees.
