Aosta West motorway exit; head in the direction of Courmayeur as far as Arvier, take the Valgrisenche, head up to Bonnes and walk around the lake as far as Usellière.

The Becca di Giasson represents a magnificent itinerary and often has great snow. It can also be covered in two days from the Bezzi refuge. It is advisable to make the excursion from April onwards when the road is open as far as Usellière.

Head up the slopes on the east from Usellière, pass close to the Arolla mountain pasture and immerse yourself in the forest still heading eastwards. The slopes become increasingly steep; head round a rocky crag on the right and you will come to the attractive plains up above. Leave the mountain pasture of Mont Forciaz on your left and carry on following the basin valley. Pass by a clearly visible moraine on your right and head up in the direction of a vast pass (in the second part of the itinerary, it is on the glacier). From here along a short, steeper stretch you will come to the vast peak dorsal.
Descend the upward itinerary.
