To the west of the majestic Mont Blanc, there are other outstanding peaks, which are sometimes neglected. On this program, I want to take you on a 2-day ascent to the Aiguille de Bionnassay. This is a challenging, fantastic climb on ice and rock, and one that you will never forget.

The Aiguille de Bionnassay has inviting fine ice and snow routes. Its peak (4,304 m) is steep and its long north face drops 4000 feet to the Glacier de Bionnassay.

In terms of difficulty, the rock climb is quite accessible, with a mid-class 5 difficulty level (French 4b), although ascents are often during the cold of early dawn. This means that it requires crampons for the snowy rock.

One of the greatest challenges of this ascent is its narrow crest, which requires a careful use of crampons, and a lot of concentration. Although the technical difficulty is not too high, the exposure and the narrow crest and thin snow ridges require confidence.

Some of the spots included in this itinerary are:

  • the Dôme de Goûter
  • the Dômes de Miage
  • the Nid d’Aigle

Due to its Advanced level, I will only take 1 climber on this program.

In terms of weather conditions, it is not advised to climb this peak when conditions are too icy. You will need glacier safety gear for this tour.

Interested in this Aiguille de Bionnassay, Normal Route ascent? Request your booking! Have a look at further 4000er programs I guide, like the Les Droites Normal Route ascent, and the Dent du Geant, Normal Route, 1-day ascent.
