At the source oh the Arc River

Little by little, you'll leave all signs of human presence behind on the first part of your hike. As you get to La Duis hamlet, you're greeted by a torrent that impishly weaves its way between rocks and pools. Having a rest here to cool off, you almost forget that the highlight still awaits you higher up, at 2,800 m of altitude.
Enter a land of contrasts, where alpine pastures and meadows merge with increasingly imposing scree slopes. The fireweeds are now behind you, and a well-marked trail ascends beyond the rocky outcrops. Here, chamois rule the land. Will they favour you with a royal visit? The closer you get to edge of the high mountains, the more the ridges seem to tear at the sky. You're there! This mountain cirque looks like an enchanted realm. This is where rivers are born.
