Book nowTrain, Acclimatize and Climb Mont Blanc With an IFMGA Guide
Mont Blanc Training & Ascent is a 5-day guided climb of Mont Blanc (4,806 m), the highest peak in Western Europe, run by IFMGA-certified Altus guides at a 2:1 guest-to-guide ratio. It runs July 4 to 10, July 11 to 17 and July 18 to 24, 2027 (or on custom dates), with one night at the Cosmiques hut and two at the Goûter hut, and builds in skills training, an acclimatization climb and a spare summit day.
Mont Blanc is the dream summit of the Alps, and good preparation is what gets people to the top. We start high at the Cosmiques hut with a day of glacier skills and crevasse rescue, then climb the Arête des Cosmiques back to the Aiguille du Midi as an acclimatization climb. With legs and lungs ready, we head for the Goûter route: two nights at the Goûter hut give us a relaxed approach, a full summit day and a built-in buffer for weather.
Highlights
- Summit attempt on Mont Blanc (4,806 m) via the Goûter route
- Glacier and crevasse rescue training below the Aiguille du Midi
- The Arête des Cosmiques, one of Chamonix’s classic alpine ridges
- A night at the Cosmiques hut and two at the Goûter hut
- Gradual acclimatization built into the plan
New to crampons? Join our Chamonix Alpine Skills & Summits the week before for skills and acclimatization.
Itinerary
- Day 1: Aiguille du Midi and the Cosmiques hut
- Meet at 8:00 at the Altus Mountain Clubhouse for a gear check, then take the Aiguille du Midi cable car to 3,842 m. We descend the snow arête onto the Col du Midi for an afternoon of glacier travel, crampon technique, self-arrest and crevasse rescue, then settle into the Cosmiques hut (3,613 m).
- Night: Cosmiques hut
- Day 2: Arête des Cosmiques
- We climb the Arête des Cosmiques, a classic ridge of granite towers and snow crests that finishes right at the Aiguille du Midi viewing platform. A great test of movement in crampons on rock, and ideal acclimatization. Cable car down for an afternoon of rest in Chamonix.
- Night: Chamonix
- Day 3: Nid d’Aigle to the Goûter hut
- The Mont Blanc Tramway takes us to the Nid d’Aigle (2,372 m). We climb past the Tête Rousse hut, cross the Grand Couloir early while it’s quiet, and scramble up the rocky Goûter ridge to the Goûter hut (3,835 m), perched on the edge of the ridge.
- +1,460 m, 5 to 6 hrs. Night: Goûter hut
- Day 4: Summit day
- We leave around 2:00 am under headlamps, climbing past the Dôme du Goûter and the Vallot shelter onto the airy Bosses ridge and the summit of Mont Blanc (4,806 m) as the sun lights up the Alps. We return to the Goûter hut for a well-earned second night.
- +970 m, 8 to 11 hrs. Night: Goûter hut
- Day 5: Descent and celebration
- An unhurried descent back down the Goûter ridge and across the couloir to the Nid d’Aigle and the tramway. Back in Chamonix by early afternoon to celebrate. If weather forced us to wait, today is our spare summit day.
- Trip ends early afternoon in Chamonix
The itinerary is a plan, not a promise. Your guide adapts the order and objectives to weather, snow and rock conditions, and group fitness.
Is this for you?
Experience and fitness
- Previous experience using crampons and an ice axe (our Alpine Skills & Summits trip is ideal)
- Very fit: able to gain 1,000 to 1,500 m in a day

How to prepare
Start training at least four months out. Focus on long days with elevation gain carrying a pack, plus back-to-back days. If you can, spend time at altitude before the trip, or join Chamonix Alpine Skills & Summits the week before for skills and acclimatization.

Frequently Asked Questions
What are my chances of reaching the summit?
Weather, conditions and acclimatization all play a role. Our two nights at the Goûter hut give us a spare day, which noticeably improves the odds, but no summit is ever guaranteed.
How do you handle altitude?
We sleep progressively higher (3,613 m, then 3,835 m) and climb an acclimatization route first. Arriving in Chamonix a few days early, or joining Chamonix Alpine Skills & Summits beforehand, helps a lot.
Is the Goûter route dangerous?
The main hazard is rockfall in the Grand Couloir. We cross it early in the day when it’s coldest and quietest, move quickly and follow current advice from local authorities.
How do I get to Chamonix?
Fly into Geneva (GVA). Chamonix is about 1 hour 15 minutes away by shared or private airport shuttle, which you can book online in advance. We’ll send recommended shuttle companies once you’re booked.
Where do I stay in the valley?
Valley nights aren’t included, so you can choose your own comfort level. We recommend the Altus Mountain Clubhouse, which is also our meeting point.
What are the mountain huts like?
Huts are staffed mountain lodges with shared dorm rooms, blankets and pillows. Dinner and breakfast are served (half board). You’ll need a sleeping bag liner and earplugs. Most high huts have no showers, and drinking water is bought at the hut, so carry cash.
Do I need travel insurance?
Yes. Mountain rescue and medical insurance that covers mountaineering at altitude is a condition of joining any Altus Alps trip. We also strongly recommend trip cancellation insurance. Please send us your policy details before the trip.
What if the weather is bad?
Your guide makes the call each evening and may change the order of days, swap to a different objective or adjust timing to make the most of the conditions. Safety comes first and summits are never guaranteed. Hut and lift costs paid to third parties can’t be refunded.
How do payments and cancellations work?
A 30% deposit secures your spot, and the balance is due 30 days before the trip. If you cancel more than 30 days out, everything you’ve paid is refunded, less the 2.5% card processing fee. Within 30 days of the trip, payments are non-refundable. Prices are in Canadian dollars plus 5% GST.
Should I tip my guide?
Tipping is never expected but always appreciated. 10 to 20% is customary, and your guide keeps all of it.
Can I rent gear?
Yes. Harness, helmet, ice axe and crampons are loaned free by Altus. Chamonix has several shops that rent mountaineering boots and clothing. Book boots in advance in June and July and try them on the day before your trip.
Do Mtn Club members get a discount?
Yes. Mtn Club members save 5% on Alps trips. Ask us about joining.
