Cerro de San Pedro
The Cerro de San Pedro is an inselberg, a term used for mountains that lie isolated from the rest of the mountains. Because of this isolation, this summit offers a fantastic view over the surrounding area, including the reservoir of Santillana, the Pedriza, the Sierra de la Cabrera and the city of Madrid, which is just 40 kilometres away. The climb to the summit is short but ascends fast. On the way back we quickly descend to a dirt road, from where we walk back the last 4.5 kilometres in a relaxed way, surrounded by the beautiful landscape of these foothills of the Sierra de Guadarrama.
- The path starts behind the stone wall on the Alto del Mojón (1). This path is easy to follow and runs initially parallel to a stone wall, which is on our left.
- The path ascends rapidly and after about 150 metres of climbing we pass through a stone wall (2). The path continues to ascend quickly without any further complication and so finally after less than an hour of walking we reach the Cerro de San Pedro (3).
- To continue our hike, we walk past the peak on the left side. Behind the peak we see a stone wall, where we turn right (4). We walk a while parallel to this wall and descend.
- To the left below us we see the dirt road to which we need to walk. However, we do not walk in a straight line towards it. Where the mountain is steeper and rockier, we turn to the right (5) and have the four towers of Madrid right in front of us.
- A little further on we go over the stone wall (6) and at the other side of the wall we see a clearer path emerge, which we follow.
- The path becomes easier and easier to follow and at a certain moment the wall turns to the left into the valley (7). We follow the path straight ahead, heading south.
- Later the path turns to the left and starts to descend faster (8). Initially we have a stone wall to our left and we see the dirt road to which we have to go right in front of us, ever closer.
- After a time of descending the path turns to the left (9). Near the dirt road we go over a stone wall and walk the last stretch to the dirt road, where we turn right (10).
- A little further on at the fork (11) we go straight on. This dirt road we follow for approximately 1.5 kilometres until a junction with another dirt road (12). Here we turn right.
- This dirt road we follow going up and down a bit for about three kilometres until we arrive at the asphalt road M-625, where we turn right (13).
- Right along the asphalt road runs a small path so there is no need to walk on the asphalt road itself. Just before we again reach the Alto del Mojón (1), at the right side of the road we find a wider path (14) which takes us back to the car.
