Leaving the campsite, we redefine the farm on your right, to take a narrow path of large trees that goes south facing the farm. We walk along the road and without the possibility of error we reach a paved road without traffic along the Esera river. Later we pass through the ruins of an old mill, then the road makes a 90º turn, at this point we leave the asphalt to pass over a river protection that leads us to the access bridge to Sesué. We continue along the river to pass by a gas tank and continuing along the track we reach a hydroelectric power station. The track becomes a path and the path becomes very pleasant next to a small dam. Soon we reach another forest track, we cross the ravine of Ramastué and Liri by a small concrete bridge and at its exit, we take the path on the left that is more bleak and without abandoning it at any time we reach the town of Castejón de Sos. Now it’s time to come back. If we do this route and the number 6 we will have traveled on foot the entire bottom of the Valley.
