This trail starts in Yebra de Basa and climbs to the Saint Orosia shrine. From there it descends to Satué on a path that is quite technical and difficult.
From the shrine, which is accessible by track including by car, there are other descents that will take you to Yebra village. These are through Casbas-Lárrede (coinciding with trail 14), Javierre del Obispo (diversion 13.1), Isún de Basa (diversion 13.2), San Román de Basa (diversion 13.3). You can also take the more direct route via the shrine trail.
START: Yebra de Basa. Church square
