Description of the route
When you get to Blavy, in the municipality of Roisan, take route 105, which intersects the private road for Alpe Viou several times, and takes you to the alp and to Tsa de Viou. From here, continue along the same trail to reach Col de Viou and the bivouac Penne Nere.
In just a short time, continue along the trail on the left of the pass and ignore 105 which descends, to reach the peak Becca di Viou from where you can enjoy a wide view on the main mountains of Aosta Valley.
