A nice climb from the El Burguillo reservoir. The first part is asphalt in very good condition (as of November 1, 2025), and the second part is a dirt track, also in very good condition. It's a demanding climb; the asphalt section offers some flatter sections, but the dirt track is practically a continuous gradient of around 10%.

Trail Run
January 23, 2023, Cabeza de la Parra

The tracks of the track pass through the Majada del Espino pass, cross the next tooth of the mountain range in the hills of Llano de Cuatro Manos and cross the meadows of Portacho del Robledo, finally climbing to the top of Cabeza de la Parra, the roof of the trail, an enormous hill of soft periglacial reliefs formed in the Primary era. At these altitudes the forest masses disappear, there are only solitary specimens of Scots or Scots pine tormented by environmental events. The trunks and branches show twisted and tortuous shapes due to the action of the snow and the wind. It would be difficult to imagine a mountain setting in the Guadarrama or Gredos mountains without these beautiful trees adorning landscapes and geographies with their suggestive plant forms. At the top there are antennas, the geodesic vertex and a small sanctuary dedicated to San Antonio de Padua with views of the Burguillo reservoir, the San Juan reservoir and the villages of Alto Alberche. The descent continues to the north through a “thigh-breaking” firebreak with a lot of loose stone. Pay attention to the exit deviation, it is the second track that comes out on the right.

Imposing chestnut tree that is the main attraction of the Castañar de El Tiemblo. It is affectionately known as "El Abuelo" and it is about a much loved tree in the area, it is estimated that it must be 525 years old. But of course, 5 centuries do not pass in vain. Shepherds used to shelter from storms until fairly recently inside its huge hollow trunk and it looks like someone set a fire near it and it's a bit charred. Still, he remains imposing and his "children" grow strong around it.
