Yaso is situated
south of the Sierra de Guara and is easily reached from the main road
between Barbastro and Huesca. Coming from Barbastro, turn right in Peraltilla and
drive towards Azara, then Abiego, Bierge, Morrano and eventually Yaso where there is also a small camping site. Alternatively leave the main road in Angüés and
drive towards Casbas, Sieso and then Labata. The mill is indicated on many maps, but it's
probably best to ask for directions before you start walking. The walk from Labata is a
bit longer but really much more enjoyable.
The mill is on the Río Formiga.
