The second stage of the Grand Combin variant of the Haute Route leads from the Refuge d’Argentière (2771 m) over three high alpine crossings to Champex-Lac (1470 m). First the Col du Chardonnet (3323 m) and the Fenêtre de Saleinaz (3261 m) are crossed, before the route continues over the Plateau du Trient and the Col des Écandies (2793 m) into the Val d’Arpette. After a long descent to Champex-Lac, the journey continues by road to Bourg-Saint-Pierre (1632 m).
With around 17.4 kilometres, 1020 m of ascent and almost 2300 m of descent, this stage is one of the more demanding days of the Haute Route. The technical passages at the Col du Chardonnet and the Col des Écandies in particular call for alpine experience. In good snow conditions, the long descent through the Val d’Arpette makes an impressive finish to the ski touring section.
