Leaving the village of Talló (a hamlet of Bellver) we take the paved track that leads to the Font d'Ingla recreational area and the Cortals refuge. A few metres further on from the Romanesque chapel of Sant Serni de Coborriu the track becomes a dirt road suitable for cars.

Once we pass the recreational area (5.7 km from Talló), on reaching a monument that supports a large stone, the track forks: the left one goes to the Cortals Refuge, we take the right one.

We pass the Can Serra farmhouse and further on, at a sharp right-hand bend, a track closed to traffic comes out on the left (7.3 km from Talló).

We leave the vehicles and continue on foot along the track barred to cars. After approximately 30 minutes a path comes out on the right (ETRS89 coordinates X: 399369 , Y: 4684249, Z: 1534 m.a.s.l.) that climbs and traverses until the path begins to descend slightly (15 min).

Among the forest a limestone outcrop can be seen. We climb off-trail up to the foot of the cliff (10 min) where we find the supposed cova d'en Pere Ferrer and 10 m above it, the avenc del Flabiol
