Sanse - Manzanares por GR124

From San Sebastián de los Reyes we circle the Dehesa de Viñuelas to connect in Tres Cantos with the Senda Real (GR124), cross Colmenar Viejo, and reach Manzanares el Real.

After Colmenar Viejo, after crossing the FFCC tracks, there is a very technical section that includes the descent to Arroyo de las Dehesas and the subsequent ascent. I had to walk most of it next to the bike (looking at the satellite photo, it seems there might be an alternative taking a track that runs parallel to the railway line, crossing it about 1 km to the NE and then connecting with the path).
