Lac d'Arpitettaz

Highlight • Lake

Lake Arpitettaz is a small mountain lake on the road to Cabane d’Arpitettaz. If you don't want to go to the Cabin, you can also make a loop to return to Zinal via the Roc de la Vache from the Lake.
However, there is a trick to getting to Lac d’Arpitettaz from Zinal. If you stay on the right bank of the river, you will have to take a difficult and steep passage called “Pas du Chasseur” where you will have to hang on to chains for part of the way. This is not ideal, especially if you have young children. Instead, stay on the left bank of the river towards the Cabane du Petit Mountet and from there follow the direction of Lac d'Arpitettaz. You will cross the river on a pretty modern bridge. This will add an extra 10 minutes to your hike but above all you will have peace of mind and be able to see the Zinal Waterfall. It's really worth the detour.

Sorebois Horn

Highlight • Summit

The Corne de Sorebois shows its typical shape with its neighboring peaks, Pointe de Tsirouc, throughout the Anniviers valley. Situated in the middle of the valley between the side valleys of Zinal and Moiry, the horn is the last summit of the range which extends northwards from the Dent Blanche. The steep north face contrasts with the smooth Sorebois mountain pasture to the east and the west face dominates the Moiry dam.

Lac des Autannes

Highlight • Lake

At the heart of the majestic Swiss Alps, in the canton of Valais, is Lake Autannes, an exceptional mountain lake that offers tranquility and an evocative atmosphere. It's hard to resist an extended break along the banks of this small lake, where you can fish. The view of the Moiry Glacier, the Weisshorn and the Dent Blanche is magnificent.

The path that runs alongside the lake has a slightly less steep gradient, inviting you to fully enjoy the panorama. As you move away from the lake in either direction, the terrain becomes steeper.

Illgraben Gorge

Highlight • Gorge

It is notoriously one of the main geologically unstable regions of Switzerland. The Illgraben massif is made up of dolomite, limestone and quartzite. Several times a year, mudslides from the Illgraben make the Rhône murky until it reaches Lake Geneva, located 90 kilometers downstream.

August 24, 2025, Lac d'Arpitettaz

I did this hike in early May 2024, just a few days after the ski season was over and the slopes had closed. The valley was completely deserted and it felt magical! The peaks were still covered in snow, but the first signs of spring were beckoning. On the final stretch to Lac d'Arpitetta, I was wading through snow up to my knees. Without proper gear I couldn’t get any farther than the small lake. The view on that crystal-clear spring day was absolutely fantastic! Check the picture I uploaded with all the peak names added.
