This stage connects the Piedmont section of SI with the Aosta Valley section. From the Jervis refuge, you ascend the West ridge towards Alpe Truc, from where you descend into the wide valley floor. You pass by Alpe Monteciousir and continue descending until you reach the Orco stream. Here, the ascent begins, taking wide turns and touching parts of the provincial road leading to Colle del Nivolet, eventually reaching the Savoia refuge.
