From the upper part of Obeix, cross the village and take the eastern path flanked by a dry stone wall. A bit lower, you will see the village of Castell-estaó and its two hills. The route goes on through a holm-oak wood characterized by the typical underbrush of this vegetal community. Several sections of the route are also composed of clay outcrops. The last part of the itinerary is more sloping until you get to the L-503 road, next to Cansat’s hut (between Molinos and La Plana de Mont-ros).
From the neighbouring village of Senterada, follow the L-503 road to Molinos. Just after the village, turn left to Astell, Obeix and Aguiró.
