I love this village. It's an ideal starting point for a hike to the Cirque de Saint-Même.

The cross of the Aulp du seuil is located at 1825m above the cirque and marks the entrance to the high plateaus.

There's still a lot to do if you want to climb the Dent de Crolles :)

A stunning summit with views of Mont Blanc. The two climbs from the Col des Ayes are relatively steep, but steel cables are installed at the more dangerous sections. The climb north via the Trou du Glaz is a bit longer and a bit easier. The climb east is a bit steeper and more exposed. The view is good, though.
