Point of departure:
Eras de Trillar. El Atazar
Medium-low difficulty path, saves in a short distance a remarkable unevenness. It provides beautiful panoramas of the El Atazar reservoir
The tour begins in the Age of Trillar, in the upper area of the village of El Atazar, goes down to an area of orchards and climbs in the direction of Peña Vallicar and the Corral de los Cotorros, left to the right. The Path, well visible, goes through a dense jaral with rosemary and stays up to it, with slight ups and downs. He crosses a first ravine called Culicalla that puts a note of contrast with the ash and willows that grow in it. The path continues along the slope of Cabeza Antón (1396 m) where you can see several pens already abandoned. It crosses the ravine of the Arredondos and passes by a sunken tub. The area becomes more rocky and finally crosses the ravine of the Eagle, pretty deep, to get to another tub, where the trail ends. The turn is done by the same way.
The route runs entirely through the Special Conservation Zone (Zec) "Lozoya River Basin and Sierra Norte". The predominant plant formation is a jaral with rosemary, with a spectacular flowering in the spring, giving way to willows, ash and thorny scrub in the ravines that line the whole way. The tour allows us to see wide panoramas of the El Atazar reservoir; Riato Valley, with its repulsed slopes of pine trees; as well as the Alto de Matachines, Sierra de Guadarrama as a backdrop. Highlights include the steep and rocky relief of the slopes of Cabeza Antón and the ravines of the Arredondos and the Eagle, carved on blackboards.
Regarding cultural heritage the route departs from the open-air museum of the Age of Trillar where several panels explain the different agricultural work. The path also allows the observation of different livestock structures such as nets and slate vats, currently abandoned. In the last of them, already in the ravine of the Eagle, you can see the names that the shepherds engraved on the stones. Also of interest is the very layout of the path built taking advantage of the slates of the land.
