This is one of the challenging adventures fitness-wise, and one of the more forgiving ones technically. The Grands Mulets route follows the same line Balmat and Paccard first climbed in 1786 — on skis, in our case — and it only exists in the window between roughly late March and early May, before the glacier crossing at La Jonction opens up too far to cross. By summer, the route stops being a route.
We build in two acclimatization days before the mountain proper. Day one, we ride the Aiguille du Midi and ski the Vallée Blanche down to the Refuge du Requin. Day two, we tour up the Aiguille du Plan straight from the hut, then ski back down through the Mer de Glace to Chamonix for a real bed before the real work starts.
Then the mountain: up to the Refuge des Grands Mulets (about 800m of touring), and the next day, the push — 1,800m over the Dôme du Goûter, past the Abri Vallot, to 4,808m. Skis back on for the descent down the north face, conditions permitting.
Guided by Gerrit Egnew — the same IFMGA guide behind our Chéré Couloir trip — plus two more IFMGA guides at his 1:2 ratio.

Arrive in Chamonix and get sorted — kit check, ski fit, and a first look at the weather window with your guide team. Welcome dinner in town before the early mornings start.
Up the Aiguille du Midi cable car, then onto the glacier: ski the Vallée Blanche down to the Refuge du Requin for the first night on ice. This is the acclimatization day — get your legs and your lungs used to altitude before anything technical starts.
A full day of ski touring up the Aiguille du Plan straight from the hut — the second acclimatization push. Then down through the Mer de Glace and the Montenvers train back to Chamonix for a real bed and a real dinner before the mountain proper.
Aiguille du Midi lift to Plan de l'Aiguille, then about 800m of ski touring across the glacier to the Refuge des Grands Mulets — sleeping at 3,057m with Mont Blanc directly overhead.
The big one. An early start out of the Grands Mulets, up over the Dôme du Goûter and past the Abri Vallot to the summit — about 1,800m of touring, with some sections on foot in crampons over hard ice. Skis back on for the descent down the north face, conditions permitting.
Booked, not hoped for. If day five got weathered out, this is the second attempt. If it went, this is a slow morning and a flight home with a very good story.
Day six is the built-in backup and it's already part of the itinerary. If both attempts get blown out, the trip becomes a very good week of ski touring around Chamonix instead — what we won't do is push a marginal weather window on a serac-exposed route. The guide's call is final.
Very. You should be comfortable covering 2,000m+ of ski touring or hiking in a day, on back-to-back days, at altitude. This is our hardest trip from a fitness standpoint — the technical climbing bar is actually lower than some of our other alpine trips, but there's no coasting through the vertical.
Not yet — we're finalizing the guide team, hut logistics and final costs. Final pricing and booking details go live once that's locked. Register your interest and we'll follow up first.
