We started Molino de la Hoz in direction of its dam to continue downstream of the Guadarrama River passing through the Puente del Retamar and arriving at Villafranca Castle. We cross it and leave in the direction of Villafranca or Aulencia Castle, which we finally see at the height of the European Space Astronomy Center (ESAC).
We return to Villafranca del Castillo and leave it following the course of the Arroyo de los Palacios passing through the Hermitage of the Virgen del Soto and arriving at Villanueva del Pardillo and arriving at the Valmayor Reservoir water conduit to catch the Cordel Segoviano about the Urbanization of Las Cuestas.
We leave on the high part towards Colmenarejo, and in Alto del Mortirolo we go down Cerro del Paredon through Cañada Real de Merinas and back to Molino de la Hoz.
Quiet route that runs between the Guadarrama River and the Arroyo de los Palacios, arriving at the Aulencia Castle or Villafranca.
