The path crosses the Tagus River over the Pareja bridge and takes the Alocén detour along a panoramic road between mountains of oaks, Pyrenean oaks and pine forests. The first kilometers to the town are a comfortable and quiet climb of about seven kilometers and with hardly any traffic. The route continues along the same road and immediately begins a fantastic descent through the pine forests of Monte de la Veguilla to the tunnels of the Entrepeñas dam. Among the trees appear the calcareous cliffs of the island of Pico de Monte Abajo and at the end the steep islet of Boca del Infierno, a symbolic stamp in the landscapes of the Alcarreño swamp. On the south side of the dam, after passing through the tunnel, there are the viewpoints of the Romanesque Bridge and Castillejo, impressive, you have to stop, lean out and contemplate the great calcareous canyon of the Tagus River in this environment, thinking about the aspect that should have before the construction of the Entrepeñas reservoir in 1956.
