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.

The climb in the proper sense ends at Planpincieux, from there you proceed on a long slight slope that allows you to enjoy the splendid nature of the valley and the immensity of Mont Blanc, after passing Lavachey, you regain altitude with a couple of hairpin bends and return on a slight slope that leads to Arpnouva where the road ends.

After crossing the bridge over the Dora Baltea, State Road 26 now winds along a straight stretch with almost zero gradients, the perfect place to look up and enjoy the view of the highest mountain in Europe.

A typical Aosta Valley village nestled in the mountains, a crossroads for Colle San Carlo, the Piccolo San Bernardo, and Pré-Saint-Didier. A little trivia: it was here that, at the end of the Second World War, a partisan brigade and a small republican brigade, putting aside all hatred, jointly opposed De Gaulle's attempt to annex the Aosta Valley to France.

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.

A challenging and relentless climb, like a good military road, it climbs with very regular gradients that allow, once you find your rhythm, to easily reach the summit. Be careful, in summer, of traffic (use extreme caution on both sides when descending) and the southern exposure, which makes it very hot in the afternoon.
