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

Be careful, if in summer it is a fairly easy passage, in winter, as the surrounding slopes are steep, it is more prudent to have crampons

1st easy part, no problem with children (better to rope them if small), 2nd part much more gassy. Return path to be avoided on rainy days (slippery mud)
