    Designed as a variant of the GR-10, the GR-88 crosses the area east of the Sierra, from North to South, starting at the pontoon in la Oliva, out of the Sierra Norte de Madrid after crossing the Jarama River, bygone La Hiruela, and plunging into the province of Guadalajara.

    The route runs through practically all the Sierra of Puebla. At its beginning it borders the meanders that the Lozoya draws before its passage through the dam of La Parra, in this area is shown a beautiful riverside forest along with hydraulic constructions of the Isabel II Canal. After passing the town of El Atazar road gains altitude up to the Hill of the Pinillas, where we get into one of the most isolated areas of the reserve of the biosphere of the Sierra del Rincón, the Valley of La Puebla. After passing through the mountain town of La Puebla de la Sierra, the path climbs to the peak of the Porrejón one of the best vantage points to see the Sierra del Rincón and the Sierra de Ayllón. More down because we see La Hiruela, example of mountain architecture, and passed this town, We continue down an oak forest to the Jarama River, the road back to gain altitude to the town of El Cardoso de la Sierra (Guadalajara).

    Hiking is an activity that carries certain risks if minimum safety guidelines are not followed, it is also a practice that is carried out in the natural environment so we must know some conservation standards that help us to make the least possible impact.
