Spectacular viewpoint in the middle of the Sierra de Guadarrama above El Espinar. The Senda de la Peña del Águila trail begins on the outskirts of the town of San Rafael, in Segovia. It is about 6 km in which we will venture into the beautiful pine forests of the area until we reach the viewpoint.

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%.

Beautiful road alongside the reservoir, very quiet. It has no paved exit.
