This short walk goes through the Canyon of Los Arcos in the La Hoz valley. The route through the gorge is made possible by a chain of footbridges. The narrow passage on the Puenta de la Toba is simply beautiful. The path continues to follow the Rio Blanco to the ruins of the Abajo mill. Here you climb to the ridge and then walk back high above the Canyon. You will certainly see griffon vultures that have their nests in the rocks just beyond the starting point. In addition, there is a chance that you will see ibexes on the mountain sides.

The walk starts in the small village of Tramacastilla and first goes on a wide dirt road along the wide valley of the Guadalaviar past fields and orchards. Afterwards it continues through a pine forest high above the Hondo valley, where you sometimes already have a view of the deep narrow gorge. You then descend to the ruins of an old water mill. Here you cross the river and walk high above the gorge with beautiful views of the river and the surrounding area. The wild goats and griffon vultures will certainly be there.
