Just at the entrance to the village and before crossing the river that gives its name to this place, we take a path to the left where we find the ruins of an old castle, not the famous one, this is on the other side of the village, and the red and white GR-10 signs, with which we will coincide until we reach Cercedilla. If we have visited the village, we should retrace our steps and recover the signs near the ruined castle. We leave the village heading west, skirting the entrance to La Pedriza Regional Park, which opens up on our right. La Pedriza is a paradise of oaks, holm oaks, pines and grassland meandering uphill, between unique granite formations that give the place its nickname (pedriza = stone), while the sierra appears higher and higher. We take a wide path that climbs up towards the Jarosa pass, where we leave the municipal district of Manzanares el Real and enter the municipal district of the community that includes the towns of Cerceda, El Boalo and Mataelpino. On the descent from the pass we pass the Cañada fountain and the hermitage of San Isidro, two of these towns being to the south of our route. From the Cañada fountain we follow this pleasant stretch of the Camino to the foothills of the sierra that takes us towards Mataelpino. When we reach this town we have the option of turning right towards the town square where we will find a fountain. We quickly leave the town by a road and then take a local road on the right, along which our path runs on the road to Navacerrada. We ascend along the road and when we reach the highest part we take a path to the right parallel to the asphalt, just where we leave the municipal district of Mataelpino, Cerceda skirts the sierra and takes us to the Vista Real housing estate, created within the municipal district of Becerril in the 1970s, which we can go round to the right, longer, along a path and without touching the road, or follow the GR which coincides with the road. When we reach the junction between the M-617 and M-607 roads, our route takes a path parallel to the latter to climb upstream along the Angostura stream. After a short but steep climb we cross the M-607 and, along a path parallel to it for dozens of metres and then surrounded by vegetation, we head towards Navacerrada. We enter the town through an area of new housing developments and head towards the centre until we reach the Plaza de los Ángeles, where the town hall is located, where we turn right and go up the steep slope of Calle Abel. At the end of this street we turn right and take a short, difficult path through pine trees towards the M-607 road. We continue for a short stretch along the hard shoulder of the road, leaving the Arcipestre de Hita hotel on our left. Cross the road to head towards the road that goes up to Puerto de Navacerrada. After about 200 m, near the restaurant La Fonda Real, we take a small road that serves the Navalmedio reservoir, and after a little more than 1.5 km we take a path on the left, and about 300 m further on a wide road, which the path leads to and which takes us to Cercedilla. To reach this town, take Avenida Manuel G. de Amezúa. At the end of this avenue, turn right towards the centre of the village; then take Avenida José Antonio and you will reach the Plaza Mayor.
