Pont-Saint-Martin motorway exit. Turn right passing the traffic light and you will come to a roundabout. Follow directions for Gressoney and turn right on the bridge a few kilometres after Fontainemore. Follow signs for “Mont Mars” as far as the Pillaz fork on the left until the road ends.

A less well known excursion at the foot of the mountain. The lower part is completely in the shade while up high, the slopes are covered in sunshine.

Carry on along the road that winds through the valley that is just slightly sloping. After about half an hour, the road heads up a steeper stretch with some turns and crosses the river over a pretty, stone bridge.
Carry on along the road as far as the Vargno Lake then head up to the left of the pretty slopes where there are a few houses. At the end, head up through the larches to the left as far as a depression: you will find yourself in front of a small river gorge that can be passed by, both on the right and left.
Further on, on a steeper stretch, you will come to a hillock where you can find an old Alpine hut.
Flat cross the slope and head into a steep, small valley, watching out for any snow falls along the last stretch. Carry on up the valley until you come to a depression. Head to the right along pretty slopes as far as the clearly visible Gragliasca Pass (2213 m).
