Route of 6.5 Km. The 100 bend path is the best known excursion of the Montsec de Rúbies, here we propose to continue until the ridge of the Montsec. Along this zigzag path, we find several Oratories to the hermitage of Sant Salvador del Bosc. We continue along the path towards the passage of Portella Blanca, the views are spectacular. We can also go down to the abandoned village of Rúbies, but the descent has a certain difficulty because of the drop and the slippery slope.
