This climb begins at the roundabout where the road to Courchevel (D91) bifurcates from the N515. It passes through some villages, amoung which Le Praz with its ski jump. Our track circumvents Courchevel 1550 and passes through Courchevel 1650 and Courchevel 1850 to end at a tiny airport (altiport). The slope is variable, one of the most tiring parts being the last kilometer, where the slope of the road (8-9% but 12% for a section of 250 meters) cannot be estimated in the barren landscape. Much of the direct surroundings of the road is ugly due to the ski resorts and the lack of vegetation in the upper parts. Traffic is dense, especially in the lower parts of the climb.
