Start at Barruera (1,097 m), just below the Church of Sant Feliu and near the river. Follow the path along the right bank, heading north on a paved track. Cross the Noguera de Tor via the old stone bridge, and continue beneath the road bridge towards Durro. The trail then follows the left bank of the river upstream, winding through meadows before climbing the mountainside. Shortly after passing the valley viewpoint, the trail reaches Riu de Boí Square (1,265 m).
