This climb follows a valley road in the Vanoise.
It starts from the village of le Villard de Planay
with some hairpin turns and a moderately steep slope (around 7%).
The rest of the climb consists of three steeper parts (up to 9%)
with easier phases in between.
The end is at a car park near Les Prioux
where in summer an amazingly large number of cars
belonging to tourists hiking from Les Prioux into the mountains may be gathered.
Though the road between Villard de Planay and Pralognan
is marked as a "Route principal" on my road map,
traffic is of a reasonable density.
Traffic after Pralognan is light anyway.
The most beautiful view is on the descent from Les Prioux to Pralognan
when several peaks among which the Pointe de la Grande Casse decorate the background.
