La Thuile

Highlight • Settlement

La Thuile, despite its only 260 inhabitants, is a very famous tourist town. In fact, its ski slopes, its hiking trails and the road that leads to Piccolo San Bernardo make La Thuile a paradise for sports enthusiasts. The center of La Thuile is enriched by the beautiful Church of San Nicola, dating back to the XII century. The name of the town comes from the French language: Tuile, in fact, means 'tile'.

Colle San Carlo

Highlight • Mountain Pass

From Morgex:
Challenging and relentless climb, from a good military road it ascends with very regular gradients that allow, once you find your rhythm, to go steadily to the top without too much trouble.
From Pré-Saint-Didier:
Decidedly easy climb to La Thuile (gradients around 4-5%), from there the climb becomes challenging with severe gradients (although not like those of the more famous Morgex side).
Be careful, in summer, of traffic (on the descent, use great caution on both sides) and of the south-facing exposure which makes it very hot in the afternoon.

View of the Mont Blanc Massif from Colle San Carlo

Highlight • Viewpoint

A beautiful lookout point, a balcony overlooking Mount Blanc. It can be reached from the road that starts next to the restaurant on San Carlo Hill for 1.5 km. The road is unpaved, but with a little care, it's also passable on a racing bike.
