Amazing views on mount blanc, lac d’ annecy and more beautiful landscape! 😍 Attention, only take the path across the ridge to the chalet de L’Alpettaz if you are a really experienced hiker and like to get some adrenaline. It is super narrow and partly really dangerous. After finishing the dangerous part there is high grass through which the hike continues.

Chalet under renovation but part of it nevertheless provides shelter.

Access is quite physical but you are largely rewarded by the sumptuous 360° landscapes once at the top 🤩

It is a tricky short walk that takes longer than stated. We needed to scramble on parts of the ascent along a mountain ridge on the very thin trail, and the path was not always obvious on some of the ridge sections. The descent is also very steep towards the end, though thankfully this very steep section is fairly short. The lake was more of a quagmire when we walked it in early September. Not your usual crystal clear mountain lake and not particularly photogenic! Enjoyable, but for the length of the walk I would say it’s a harder intermediate.

An incredible view! Relatively aerial trail with a few wired passages. But this ridge is worth the detour! Be careful though, you will necessarily want to follow it to the Belle Étoile

Very nice view with an outstanding 360° Alpine panorama! Coming from the north via Le pas de l'âne, don't underestimate the difficulty of the ridge. At the end of February there was still a lot of snow and the fuses are not in place over the entire length. In parts, the hike has more of a via ferrata character. The ridge is sometimes very narrow and it feels like several hundred meters down to the left and right. But if you are prepared for it and are used to challenging terrain, then it is a super nice hike and absolutely recommendable!

A small summit at 1814m straddling Savoie and Haute-Savoie. From here there are superb views of Lake Annecy and Mont Blanc.
