Route that, due to its slope and kilometers, demands very good physical and technical level. Part of Yebra de Basa and ascends for the track until the Hermitage of Santa Orosia. From there we also approach by track until the skirt of the peak Oturia, surrounding it by its east face to take a descent that combines with stretches of path to the vicinity of the Barranco de Oliván. Once there we take another track in ascending direction, we cross the ravine and arrive to the Hermitage of San Blas, passing by the hill of Basarán. From there we continue on a track until we reach again at the foot of the Oturia peak, completing a circular route. Once at this point we can return to Yebra by the same path or go down some of the different paths that lead to the villages of Lárrede, Javierre del Obispo, Satué, Isún de Basa or San Román de Basa, all of them very technical. From any of these nuclei it is possible to return to Yebra.
START: Yebra de Basa. Church square
