Starting in Barruera, follow the trail to Durro (Hiking Trail 4). Upon reaching Durro (1,390 m), begin below the Church of the Nativity, heading left and passing through a stone arch on the right. Continue along the path, which initially coincides with the trail to Barruera, maintaining a steady elevation as it winds around the mountain. Pass through meadows and terraces before entering the Obac pine forest, eventually arriving at the abandoned village of Saraís (1,340 m).

From Barruera (1,097 m), take the trail towards Cardet (Hiking Trail 3). Upon reaching the Church of Santa Maria de Cardet (1,197 m), skirt the southern edge of the village and descend along the ravine to the L-500 road near the Cardet Dam (1,088 m). Continue to the Pont de Saraís, cross the bridge over the Noguera de Tor River, and follow the river to the Pont de Saraís (1,006 m). At this point, cross the L-500 road and take the uphill path to Coll (Hiking Trail 1).

Begin in Barruera (1,097 m) and follow the path towards Erill la Vall (Hiking Trail 6). Upon reaching Erill la Vall (1,247 m), descend toward the Church of Santa Eulàlia and continue towards Boí (1,265 m). Follow the trail as it goes down to the L-500 road and cross it. After crossing, take the stairs leading to a bridge over the Noguera de Tor River, then ascend to the parking area in Boí. From Boí, proceed towards Taüll (Hiking Trail 8) (1,480 m). After reaching Taüll, retrace the same path back to Boí.

The trail starts on Calle Major in Barruera and leads to a track. Once on the track, a footpath provides shortcuts. Just before reaching the Hermitage of Sant Salvador, leave the track and turn left, ascending through the gorge to the ridge. Follow the ridge all the way to the summit.

From Durro (1,390 m), head south, crossing the bridge over the Cortina Ravine. A short climb brings you to a right turn that leads to the Hermitage of Sant Quirc via the old path. From the hermitage, follow the forest track for about 700 meters before turning left onto an uphill trail that eventually reconnects with the track. Continue along the track to the right until you reach a curve, where a path branches off to a viewpoint offering breathtaking views of the valley. From the viewpoint, follow the clearly marked trail through forests and meadows, which will bring you back to Durro.

From Durro (1.370m), head E along the trail that leads to Barruera. Almost without loosing height, surround the mountain, first along meadows and terraces and then through the “Pinar de l’Obac” pine grove. Continue towards the S along the sunny side of the hill, up to the uninhabited village of Saraís (1.330m).

Due to the bad condition of its houses, go very carefully through Saraís. Leave the village on its lower point, taking the trail that -in a constant descent and in many legs flanked by dry-stone walls- leads to Pont de Saraís (1.015m).

Follow the L-501 road toward Pla de l’Ermita. Park about 500 meters past the village, just before the Pont de la Ribera (1,692 m). The trail runs along the right bank of the Sant Martí River. Shortly before reaching a partially collapsed shepherd’s hut, follow the marked path with yellow posts, which ascends to the Lake Pessó (2,493 m).

Take the L-500 road toward Caldes de Boí and park in on the left, just past the Toirigo information booth (1,500 m). From this parking area, the trail begins and leads to Lake Gémena (2,257 m) through the Llubriqueto Plateau.

Take the L-500 road towards Caldes de Boí and park at Cavallers (1,784 m). From there, the trail starts on the right, just above the reservoir, and takes you to Lake Negre (2,147 m) and the Refugi de Ventosa i Calvell (2,215 m). Along the way, you’ll pass through Pletiu de Riumalo and the striking area known as Les Llastres de la Morta.

The route to Estany Llong (2,000 m) follows the course of the San Nicolau River, passing through Planell Gran and the Aiguadassi meadows.
