Large, completely free parking lot in a great location

Be sure to arrive early. Despite the large parking lot, it fills up quickly. We arrived at 7:00 AM because of the heat, and there was plenty of room. By noon, when we left, there was a fight for our spot.

A beautiful family hike below Les Fiz and Pormenaz, with a beautiful view of Mont Blanc and the valley. From here, you can access Lake Pormenaz via three trails, including "La Chorde," reserved for those with mountain feet, with cable passages and ladders, and "Les Argentières," a less challenging route with cable passages and steps, and then the one passing through the Pierre à l'Ours on the mountainside.

I loved this lake! and even more so to go around it (with some complicated steps) and see it full of fish.
