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 red dot marker keeps you from having to be with your nose in your phone, but the GPX track is essential if you miss a red dot!😊

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.

Unfortunately, due to French national park rules, dogs are not allowed to cross the trail - not even if they are on a leash. Camping is also prohibited.
