This town of just over 100 inhabitants owes its name to the number of oaks and cistus that populate the area. Within its municipal term is the unpopulated area of El Villar (from which one of the Lozoya reservoirs takes its name). However, currently nothing remains of this place.

El Berrueco is a town of about 800 inhabitants, located very close to the El Atazar reservoir. In its municipal term is the boyal pasture of El Berrueco, a large expanse of pastures where ash trees, oaks and junipers abound. The hiking trails in the area are highly recommended, especially in spring when the grass turns green.

Cervera de Buitrago is a pretty town of stone houses that claims to be a fishing town. Thanks to the Lozoya River and the construction of the El Atazar reservoir in the 20th century, the inhabitants were able to benefit from this industry to supply themselves and do business with the surrounding towns. Today there is an important yacht club where you can practice all kinds of marine sports.
