The departure is from the clearing near Balziglia, where you can leave your car. Go down an asphalt road to the hamlet of Piccolo Passet, where you turn left onto a path in the direction of the gorges and the mill of Piccolo Passet. Once past the mill, continue along a cart track, cross the Germanasca stream and reach the asphalt provincial road near the hamlet of Reynaud. Continue along the provincial road as far as the crossroads for Salza. Ignore the deviation for Campo la Salza (asphalt road) and for Galleria Gianna (path) and you will reach the village of Didiero, seat of the municipality of Salza. Go past the town hall and continue for a few hundred metres on a dirt road for Colletto delle Fontane to the crossroads. Follow the dirt road from here for a few hundred metres and then turn right onto the path. From this junction, the path crosses the dirt road several times until it joins it just below the pass. When you reach the pass, there is a fountain in the middle of a four-way crossroads. Continue from the pass, going through the meadow where a picnic area has been set up, and climb up to Colle di Serrevecchio. From the hill you descend along paths and old mule tracks, crossing the villages of Serrevecchio and Bounous, until you reach Rodoretto. Follow the asphalt road to the left of the village until you reach a crossroads: ignore the asphalt road that leads into the Rodoretto valley and take the dirt track that descends towards the stream. At the stone bridge, ignore some variations on the path and continue along the dirt track until you reach the junction with the main path, which you take as far as Colle Galmont, cutting several times across a forest track. From Colle Galmonte you go over some rough terrain and then reach a second pass where you will come across the forest track once more. From here you turn left and continue along the path and after about one km you come to a dirt track that you follow as far as the hamlet of Cugno, shortly after which the road becomes asphalt. Continue to the junction with the provincial road at the bottom of the valley and after a few minutes you will reach Ghigo di Prali.

In 2016, upon suggestion of the Municipality of Massello a historic variant was recognised in Castello di Balziglia on the intersection of trail ETOS 200 The place known as "dell'Assedio" recalls the historical siege occured during the historic return.
