From Vernant car park, take the path to the left of the chair lift towards Lake Airon. It is a very easy walk along a path with hardly any altitude change. The path goes through Corbalanche woods. When you come out of the woods, you will discover a beautiful viewpoint over the Aravis mountains and the Arve Valley. Next, you will come out into an Alpine pasture, with herds of cows and goats, before reaching the lake. Retrace your steps for the return journey.
