Get to Blavy, 1.471m, which can be accessed via St. Christophe, east of Aosta.
Follow the well marked trail out of Blavy into the forest. In there, the marking will alternatively be red/white, but reassure yourself you keep your general direction towards NE. During the ascent, you will cross the street twice, after the second crossing you can already see the Alpe di Viou (1,5h). Behind the Alpe, the trail merges for a while with trail #22 eastwards, but will soon turn NE again. After a relaxing rather plain part of the trail you will reach the foot of the Becca di Viou and will have to follow a steep rocky trail towards the Col di Viou (3,5h passed). Once you made it up there, the final ascent to the peak is a short walk, which might require some easy climbing in parts.
Usual hiking gear required, bring plenty of water, a map and a compass.
