Halfway along the Dents-du-Midi tour. Easy but quite long route. Very beautiful view of Lake Geneva at the start of the route then over the Illiez valley to Champéry. Some parts are a bit boring, you can't see the end! Possibility of stopping before the descent from the Antème hut and its very beautiful lakes. Very mineral place at the foot of the Dent-du-Midi where you can notice the very beautiful white layer, a sedimentary rock from the Cretaceous period (between 145 and 66 million years ago)

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.
