The Molar watchtower is one of the six old defensive watchtowers of the Mayrit mountain range. Visibly rebuilt, it has an extensive view of the surrounding valleys and allowed communication between different towers through fire signals or, failing that, smoke. These messages could travel 200 kilometers in 45 minutes, eliminating the Christian factor from the Christian troops. Thanks to its strategic positioning, today its foot serves as a viewpoint of the Sierra Norte and Cuerda Larga.

It is worth it for the incredible views that can be seen from the top. A complete panoramic view of the Atazar but it is difficult to get there with a road bike. Likewise, from the road you can see the views and the tower itself is El Barrueco.

Park between Tres Cantos and Soto de Viñuelas where you can enjoy nature very close to the city. In fact, being in this park is very similar to being in the countryside. Regular place for walkers and athletes.
