The trail starts at Prato Selvest (1660 m). Cross the Legogno bridge and continue on the right, taking the road through the larch trees. After half an hour, you reach Grange Golausa (1911 m). From here the trail passes along the foot of Rocca la Meja. After crossing the small pass at 2304 metres, a descent takes you to the basin of Lago Nero (Lake), which is like a terrace that overlooks the Preit di Canosio valley.
Walking along the right-hand side of the lake, take the descent route, along which you can admire rhododendron shrubs. You reach Grange Chiarcarloso (2080 m) and then take the path leading downwards to return to the starting point. By making a small detour, once you get back to the starting point, you can visit the Pis del Passet waterfall (1610 m).
