Arêtes de Rochefort & Dent du Géant Duration

Reach the noticable peak of Dent du Géant (4013 m) in the Mont Blanc massif and explore one of the most beautiful snow ridges in the Alps - Arêtes de Rochefort

Chamonix, France
2 days

The program combines two completely distinct climbs which are brought together by the amount of exposure to offer and their proximity.

The stunning granite spire of the Dent du Geant and the razor sharp snow and ice of the Aretes de Rochefort represent a hallmark of what the elements can achieve. A purity of form providing a mind bending exposure to the ones who dare venture.

Each of these classical climbs is a serious undertaking itself but being in a close proximity and sharing the same approach makes it possible to combine them in a single outing! Having the better snow conditions for the Aretes in the morning and having the route on the Geant on its shady SW face makes it quite logical to begin with Rochefort and to scale the Geant on the way back

Depending on conditions and your speed the climbs can be done in a single day starting with the first cable car from Courmayeur. The advantage is that we can skip lodging expenses. If we decide to go for a two day trip, the itinerary is as follows:

Day 1

We ascend to Torino hut (3375m) for a gentle acclimatisation and skill revision on any of the surrounding lesser climbs: Aiguille d'Entrèves or Aiguille des Marbrees. Overnight at Torino hut.
