An easy but fairly challenging trail with a fairly steep ascent and descent.
From Orsières station, cross the railway line and walk alongside it, then head towards Chez-les-Reuses and Champex-Lac. Do pop over to take a look at the lake. The descent follows the Tour du Mont-Blanc route as far as the Chalet de l’Affe. Then take the Route du Niolet to Prassurny, before returning to Orsières via the Chemin de St-Nicolas.
