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

The climb to the charming Som from the Col de Porte is always a treat. There are some very steep sections, but the view at the top is worth it. Be careful on the descent: uneven road, tight bends, cars.

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.
