For a stopover during the Tour des lacs des 7 Laux or just a break. A very friendly team with simple but quality cuisine and more than reasonable prices. In short, a break is essential.

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.
