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.

down this side of the mountain it's rough and loose gravel so not ideal for a road bike, even though I did to get to see the bridge !

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.
