Col du Petit Saint Bernard (2188 m)

Highlight • Mountain Pass

The Col du Petit-Saint-Bernard from Bourg Saint Maurice is 26.50 km long with a total drop of 1348 m. The average gradient is 5.1% with maximum gradients of 8.1%.

It's an epic climb to do in the Tarentaise Valley. It is only accessible during the summer months due to its high altitude. There are spectacular views of Mont Blanc as you ascend, then incredible views as you descend.

It is believed that Hanibal used this mountain pass to cross the border into Italy.

Colle del Piccolo San Bernardo

Highlight • Mountain Pass

The Colle del Piccolo San Bernardo, at an altitude of 2,188 meters, has connected the Aosta Valley with the French Tarentaise for centuries. Already frequented in pre-Roman times and later crossed by the Via delle Gallie, it still preserves an exceptional historical and archaeological heritage today, including the Cromlech, the Column of Jupiter, and the ancient Hospice.

Easy walk in French territory, just beyond the Little Saint Bernard pass.
We start from the square behind the old hospice of the Little Saint Bernard pass (now reopened). The path is well marked and the climb to the lake is a bit steep but very doable (we did it immersed in the clouds). Once we reach the lake, once …
