The route

One of the most spectacular stages, and the airiest. From Tré-le-Champ, the trail climbs into the Aiguilles Rouges Nature Reserve and tackles a series of ladders and metal steps to reach the Aiguillette d'Argentière. The section is not technical but it is impressive: anyone prone to vertigo can avoid it by climbing up from the Col des Montets instead.

You then reach the Tête aux Vents (2,130 m), followed by the Grand Balcon Sud, facing the Aiguille Verte, the Drus and the Mer de Glace. The detour to Lac Blanc (2,352 m), where the Mont Blanc massif is reflected in the water, is all but unmissable: it adds about 1 hr 30 min of walking.

The stage ends at La Flégère, a high-altitude lift station linked to Chamonix (Les Praz) by cable car. Depending on the accommodation available, many hikers go down to sleep in the valley and come back up the next day.

Practical tips

  • The Refuge du Lac Blanc has a small capacity and fills up very quickly: book as soon as reservations open.
  • In the Aiguilles Rouges reserve, bivouacking is regulated from 1 June to 30 September (designated areas, booking required) and prohibited in the Lac Blanc basin.
  • The La Flégère cable car takes you down to Chamonix if you want to sleep in the valley.
