Valley floor access point a few minutes from Aosta, located near the confluence of the Dora Baltea and the Buthier stream. Several ascents to the surrounding slopes start from here.

Passing under the imposing covered viaduct that leads to the tunnel marks the beginning of the toughest part of the climb: the gradients become more demanding (though never prohibitive), the fatigue accumulated over the previous 20 km takes its toll, and the winds from Switzerland begin to lash you... you're officially in the high mountains, after all, that's why you came here. If the day is one of the worst, with strong winds from the pass, these last 10 km will be a nightmare, but the beauty and majesty of the landscape will more than make up for even the most intense of efforts.

A small village located at the start of the Valgrisenche climb; interesting fact: this is the birthplace of Maurice Garin, winner of the first Tour de France.

A clearing at the end of the Valgrisenche road, from here you can enjoy an excellent view of the artificial lake and the surrounding mountains.

Very irregular and decidedly challenging climb, especially in the initial kilometres which have steep gradients and, for over a kilometre, greater than 10%.
