Majadahonda-Río Guadarrama-Urb. El Bosque

Route starting from Majadahonda that runs alongside the Guadarrama River on both banks. The initial part is mostly downhill until reaching the river, so on the way back, you have to climb back up. It mainly runs on paths, although there is a stretch of road with almost no traffic (linking to the NASA parabola area). It traverses oak groves and pine forests of high ecological value.
