The starting point is located at the exit of La Codosera, on the Chandavila road. After passing the restaurant El Quinto C., we take the first path to the left, skirting the Castillo mountain and passing under the imposing figure of the Sacred Heart of Jesus that stands on one of its towers. We leave the town through San Pedro street, taking the old Chandavila road, which leads us, among centuries-old cork oaks, to the Moto-Cross circuit. The section coincides with the return of two other trails, the PR-BA 101 and the SL-BA 139. After the circuit, we will continue south, taking the "vereda del medio", crossing cereal fields, mountains covered with Mediterranean forest and scrubland, the Regato de la Venta, and a small eucalyptus grove, to reach another road perpendicular to the one we are on, next to the hamlet of El Marco. If we follow this road to the right, we can visit this border village. Then we will resume the route at the previous point but taking the road to the left heading east. We will follow this road for 1 km until we reach a junction where we turn left heading north. This road takes us back to La Codosera. We will cross the Sierra de Valleseco and the stream of La Venta and descend to a eucalyptus grove, where we will continue straight ahead, then to the left, and then to the right, very close to the Moto-Cross circuit. After a steep descent, the road, flanked by stone walls and dense vegetation, crosses pasture areas, olive groves, and holm oak meadows. Finally, we will enter the town through the area called El Potril and the Barrio de San Miguel, and then take San Pedro and Ventosa street, which will lead us back to the starting point.
