The ascent of Mont Blanc via the Bionnassay is an exceptional experience reserved for seasoned mountaineers. Far from the crowds of the classic routes, this itinerary stands out for its wild atmosphere, technical nature, and the elegance of its snowy ridge.
From the Durier Hut, perched on the col at the French–Italian border, the route leads to the Aiguille de Bionnassay and its famous razor-sharp ridge, one of the finest in the massif. The traverse then continues toward the Piton des Italiens, the Dôme du Goûter, and the majestic Bosses Ridge all the way to the summit of Mont Blanc (4810 m).
This three-day ascent combines technical commitment, glacier travel, and the pleasure of moving through a magnificent high-mountain environment. A truly exceptional climb to experience one-on-one with your guide.
From mid-June to September depending on conditions.

A sustained ridge climb requiring solid mountaineering experience. Thorough preparation is essential for this ascent and it is intended for very fit individuals. You may be walking for up to about 12 hours per day, so you must prepare by training with long-duration cardio sessions. Endurance sports: cycling, running
And don’t forget that for 3 days you’ll be hiking with an 8-kilogram backpack, which significantly increases the effort required, so during your training outings make sure to walk with this additional weight.
You will be traveling on a high-mountain route and must be aware of the hazards associated with this activity (crevasses, serac fall, rockfall, avalanches, very low temperatures).
