in Chamonix-Mont-Blanc
Info spéciale

Looking for a nice hike? Please consult the mountain conditions before leaving.

La Chamoniarde website.



The Lac Cornu is one of the most popular walking destinations. Fishing is possible in the lake. With its curious shape, it is nestled in a wild and quiet setting. Natural reserve of the Aiguille Rouges.

From the top of the Planpraz gondola, go up towards the plateau that you cross, pass by the "Altitude 2000" restaurant and the chairlift station and go towards the arrival towers of the chairlifts and ski lifts. Leave on the left the paths going to the Brévent and the Col du Brévent: use the track leading to the Flégère. At about 200m, take the upper left path crossing large grassy slopes. Pass on a promontory, cross a large scree and cross a small gap. Then go up a rather steep slope by a few switchbacks leading to the Col Cornu. Going a little further, we can see below the Lac Cornu. Reach it by descending a path often covered with snow.
Return by the same route.
