Magnificent lake! Accessible to all! As a bonus, you'll find ibexes and a few marmots if you're lucky. For the more courageous, you can climb to an altitude of 2,900 m by continuing on the path with a magnificent view if the sky is clear!

Favor the climb via Sarcenas, almost no cars

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.
