We started the hike from the Sevan Devant parking area, taking the path on the left. The trail begins by crossing a meadow with a stunning view of the Dents du Midi. If you go in June, there’s a good chance you’ll come across a few cows peacefully lounging along the way.

After about 20 minutes of easy walking, the lake already comes into view. It’s a lovely spot to take a break or enjoy a picnic. I recommend continuing the climb for another ten minutes or so up to the Chalets d’Arvouin (1,720 m), which offer a panoramic view of the lake below.

From the chalets, you have two options: Col de Vernaz (1,815 m) or Col d’Arvouin (1,864 m), which is the one I chose. The trail is well marked and not technically difficult, but it does get steeper in places, making it ideal if you're looking for a bit more of a challenge.

It takes about 30 minutes to reach the col, located right on the French-Swiss border. From there, you’ll enjoy a beautiful view of Le Linleu and the surrounding Swiss mountains. With a bit of luck, you might even spot a few ibexes.

For the return, we simply turned around and followed the same path back.
