The walk leaves at the info sign next to the entrance to Camping Sierra Espuña. You leave the village past the school and start to ascend to an iron gate that gives access to the Sierra Espuña. At a viewpoint you have a beautiful view of the striking mountain Morrón de Espuña (1444 meters). Then it goes via beautiful forest paths in the direction of Casa Leiva and the old sanatorium for tuberculosis patients that was in use until the 30's of last century. Shortly thereafter you arrive at the recreation area and parking La Perdiz. From here you follow the path of the dinosaurs for one kilometer, there is a stone on the path of which it is said that a paw print of a dinosaur can be seen there. A little further you pass an old well and a suspension bridge over the Barranco de Leyva. You now enter the valley of the Leyva and then turn right into the Barranco de las Brujas, the valley of the witches. The stony path descends firmly until you come back at the edge of El Berro.
