The trail begins at Tarter Square in Erill la Vall, crossing the ravine before following a footpath through the forest. It gradually ascends through open meadows to Basco Pass, which offers breathtaking views of the valley. From there, the trail continues at a consistent elevation towards the easily visible Gelada Pass, a natural passage linking Vall de Boí with Barravés Valley.
