28 km long and including 19 hairpins, this is one of the longest climbs in Savoie Mont Blanc. Fortunately, the gradient is never extreme (average 5%) so it is possible to maintain a reasonable cadence.
The final 8 km from La Rosière to the Franco-Italian border at an altitude of 2188 m can feel very long, so why not have a bite to eat and soak up the “high-mountain” atmosphere of this historic pass before enjoying the exhilarating descent.
From 01/06 to 31/10.
Depending on the weather.
