From Morgex:
Challenging and relentless climb, from a good military road it ascends with very regular gradients that allow, once you find your rhythm, to go steadily to the top without too much trouble.
From Pré-Saint-Didier:
Decidedly easy climb to La Thuile (gradients around 4-5%), from there the climb becomes challenging with severe gradients (although not like those of the more famous Morgex side).
Be careful, in summer, of traffic (on the descent, use great caution on both sides) and of the south-facing exposure which makes it very hot in the afternoon.

View of the Mont Blanc Massif from Colle San Carlo

Highlight • Viewpoint

A beautiful lookout point, a balcony overlooking Mount Blanc. It can be reached from the road that starts next to the restaurant on San Carlo Hill for 1.5 km. The road is unpaved, but with a little care, it's also passable on a racing bike.

Marais Nature Reserve

Highlight • Natural Monument

Cycle path that connects Morgex to La Salle within the Marais Nature Reserve. The route follows a stretch of Dora Baltea crossing its alluvial plain, where there are lakes, marshes and hygrophilous woods. It is almost 4 kilometers long and allows you to avoid the Aosta state road which can be busy at peak times.
