From Alpe Caougis take path 129 towards the Chiot del cavallo. After the marble quarry about 15 minutes from the start, take the path indicated on the left towards Alpe Subiasco, signposted 126. The path, which has been recently restored after the mountain pasture started to be used again, descends gently through meadows and gullies below the watershed between the Subiasco river basins and the Conca dei tredici laghi, in Val Germanasca, and finally reaches the farmhouses at Alpe Subiasco (1874 m). Pass the houses, descend to the left along the path and cross the pastures below the steep wall of Roccia Pejrun until you reach the alpine cabins at the locality of Barma d'Aut (1513 m). At the pasture, we find path 128 marked "Vallone degli Invincibili" which leads up from the hamlet of Bessè di Villar Pellice. Our itinerary continues instead towards the West (trail sign 127) crossing the Subiasco stream to reach Rocca Chabert (1450), an imposing rocky outcrop overlooking the valley. From here, the path becomes much easier and in a short time you reach Serre Sarsena (1328 m). From here, continue on a dirt road to reach the locality of Sarsena Superiore (1221 m) where you take the dirt road (Route 125) of the "Glorioso Rimpatrio dei Valdesi" (GRV) long distance trail. Continue along this, touching the localities of Serre Cruel (1334 m) and Cruel (1285 m) before ascending to the locality of Giausart d'Amount, where the mule track turns into a path, which heads towards the Cruello valley and arrives at Prapic (1336 m). Above us the great spire of Giussarant dominates, offering shelter to the Waldensians during the persecutions. The path climbs for a short distance to reach a bridge at a locality called Passerelle (1440 m), and dominated by Punta dell’Aguglietta. Beyond the bridge, the path climbs steep hairpin bends and trends north until reaching the Grange Giulian (2105 m) interspersed with rocky boulders where the Giulian Municipal mountain shelter is situated. From here, continue in a northerly direction by taking the mule track that heads up through the pastures to the summit of colle Giulian (2451 m).
From the locality of Prapic, it is also possible to go down to the Cruello stream and go up the opposite side along a forest track that leads to the locality of Taja where Rifugio Cruello is situated (1250 m).
