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%) 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.
