This is a classic circuit which leads across a beautiful, high route above treeline and underneath the towering Chamonix ‘Aiguilles’, or needles. The route climbs to the Refuge Plan de l’Aiguille before traversing to Montenvers, which has a commanding view over the Mer de Glace glacier and the ‘other side’ of the Aiguilles. It is also possible to use the Aiguille du Midi cable car or Montenvers train to avoid either the ascent or descent.
