The hallmark and leading star of the scenery found in the Northern mountains (Sierra Norte) is the water. The watercourses of the Lozoya and Jarama rivers, as well as other less important. streams, create an ensemble of natural, rural, and cultural landscape, and form the foundations around which some counties and many municipalities have been formed. This is one of the most beautiful locations of the Comunidad de Madrid.
The 41 municipalities have not lost the traditional spirit over the years, and have maintained the ancestral architecture of the urban areas which, in turn, adds a particular beauty to the scenery. In this territory, two distinct zones can be defined. The mountain, representing the largest part of the territory, and the countryside, which is present at the southeast end.
