A small village at the foot of the Colde l'Iseran. Refill your water supplies at the tourist information office or refuel at the supermarket or bars.

Splendid loops to or from La Rosière. The other route to the Col du Petit Saint-Bernard is via Montvalezan.

At the station, you have done about 2/3 of the climb to the Petit Saint-Bernard pass from Bourg Saint-Maurice: courage!
