Cycling up the Col du Petit-Saint-Bernard
IGN cards
Description
Climb a mountain pass over 2000 metres high by bike today! Thanks to its moderate, even gradient of around 5% on average, you'll be able to add the Petit-Saint-Bernard to your list of achievements. And you can say: I did it!
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.
