Start in Barruera (1,097 m), just below the Church of Sant Feliu. Follow the path along the right bank of the river, heading north. Pass the old stone bridge on your right, and continue beneath the Durro road bridge. At the cement works, take a left turn, following the river upstream. After a short climb through areas bordered by dry stone walls, the trail reaches a bend in the old road. From here, take a right turn, passing through the tunnel beneath the L-500 road. Finally, ascend a section flanked by dry stone walls, which will lead you to Erill la Vall (1,250 m).
