Levels

Mountaineering

Beginner

Mountaineering is a demanding sport; consequently, there is no "beginner" physical level for it. If you have never mountaineered before, you can aim for an intermediate or advanced level.

Intermediate

For fit hikers who wish to experience the high mountains. No specific mountaineering skills are required; the crampon work is straightforward. Guides are on hand to provide instruction and ensure your safety. The daily elevation gain generally ranges from 700 to a maximum of 1,000 meters.

Confirmed

For those who engage in endurance or mountain sports (running, cycling, trail running, rock climbing, trekking, etc.) three or more times a week. You are capable of hiking for long hours in the mountains and ascending around 1,500 meters in a single day. Ideally, you have some prior high-altitude experience (such as walking in crampons), though this is not essential if you are in excellent physical condition. To aid acclimatization, it is recommended to go mountain hiking in the days leading up to the trip.

Advanced

For those who regularly practice endurance or mountain sports (running, cycling, trail running, rock climbing, trekking, etc.)—at least four times a week. You are capable of hiking for over eight hours in the mountains and ascending between 1,500 and 2,000 vertical meters in a single day. You have mastered crampon techniques. Prior mountaineering experience (ascents or ice training) is mandatory.

Expert

For those in excellent physical condition who regularly engage in mountain activities (rock climbing, mountaineering, ice climbing, etc.): you have mastered mountaineering techniques and are capable of undertaking climbs rated D or higher.

In a few words

Prepare yourself for a true high-mountain challenge in the heart of the most beautiful massifs of the Alps. This demanding mountaineering course is for enthusiasts with excellent physical condition and prior mastery of cramponing , rope work, and ice axe use.

Your adventure unfolds in two complementary stages. The first part takes you to Italy, to the Gran Paradiso massif, for three days of acclimatization and technical preparation. After reviewing the basic techniques through snow and ice climbing schools, you will ascend Gran Paradiso (4,061 m) via the Royal Route to refine your skills in a glacial environment.

After a night of rest in Chamonix, it's time for the main objective: the ascent of Mont Blanc over three days. Gradually climbing the Dôme du Goûter and then the spectacular Arête des Bosses, linking these major routes demands sustained physical commitment. Accompanied by your high-mountain guide , you'll traverse breathtaking scenery before reaching this legendary summit , the ultimate reward for an exceptional journey.

Meet at 9:00 AM in Chamonix for a fitting of individual equipment (rentals may apply). Briefing with your guide. Departure in your own vehicles towards the village of Pont in the Valsavarenche valley. We will cross the Mont Blanc Tunnel and descend into the Aosta Valley before ascending towards Gran Paradiso National Park. From the village of Pont (1960m), the climb to the Victor Emmanuel II refuge is magnificent and an excellent warm-up, with the many ibex inhabiting the area watching over us. This refuge is one of the most welcoming in the Alps, and we will spend two nights there.

Ascent of Gran Paradiso
- Activity Mountaineering
- Duration of the activity 6h
- Positive elevation gain 1300 m
- Negative elevation 1300 m
- Maximum altitude 4061 m
- Exposed passages Yes
- Accommodation Refuge
- Breakfast included
- Lunch included
- Dinner included
An early start for the ascent of Gran Paradiso via its normal route, a round trip. It's one of the most beautiful viewpoints in the Alps, offering views of Mont Viso, Monte Rosa, the Mont Blanc massif, and so many other peaks! The route features varied glacial slopes, culminating in an airy, rocky section to reach the summit statue of the Virgin Mary. Reaching the 4000m mark provides excellent acclimatization for Mont Blanc. A leisurely descent then leads to the refuge.
Day 2
Technical Day
- Activity Mountaineering
- Duration of the activity 4h
- Positive elevation gain 600 m
- Accommodation Refuge
- Breakfast included
- Lunch included
- Dinner included
This day's activities will be determined by the local guide based on the group's skill level and mountain conditions: ice climbing, rock climbing, cramponing above the refuge. Then a leisurely descent to the refuge and down to the village of Pont. Return to Chamonix and rest! Back at the gîte, the guide will gather you to discuss the rest of the program based on the weather forecast and mountain conditions. He will also form the rope teams for the ascent of Mont Blanc.
Day 3
Mont Blanc Tramway, Eagle's Nest, Tête Rousse Refuge
- Activity Mountaineering
- Duration of the activity 4h
- Positive elevation gain 850 m
- Accommodation Refuge
- Breakfast included
- Lunch included
- Dinner included
The first easy stage of our Mont Blanc ascent: we set off late morning to reach the village of Les Houches. The support guides join the group, and the rope teams are formed for the climb. We take the cable car to Bellevue and then the Mont Blanc tramway to the Nid d'Aigle. The first section is easy, following the Rognes ridge and a quick traverse on the north face, before we emerge onto a snowy plateau at the end of which lies the Tête Rousse refuge. The afternoon is dedicated to rest and acclimatization, enjoying the magnificent view of the north face of the Bionnassay. (Should weather and/or safety conditions prevent us from carrying out the initial program, it will be modified, and an alternative program will be implemented, such as the ascent of Monte Rosa.)
Day 4
Ascent of Mont Blanc and overnight stay at the Goûter refuge
- Activity Mountaineering
- Duration of the activity 8h
- Positive elevation gain 1600 m
- Negative elevation 1000 m
- Exposed passages Yes
- Accommodation Refuge
- Breakfast included
- Lunch included
- Dinner included
This ascent is made via the rocky face of the Aiguille du Goûter. A wide couloir at the bottom of the slope is exposed to rockfall, so it is very important to follow the guide's instructions carefully. The rest of the climb follows a shallow spur with sections equipped with cables or ropes: these require the use of hands and at times resemble scrambling. As night falls, the sense of time disappears, and we soon reach the Dôme du Goûter at 4304m. We are at the Vallot bivouac refuge, which is unguarded and theoretically serves as a shelter for climbers in difficulty. It is often here that the sun joins us, bringing with it a renewed vigor. The summit draws nearer, the Bosses ridge begins, and for a few hours we will be suspended between sky and earth on a magnificent and sometimes airy ridge. The guide will then ask you to ensure that the rope is taut. Finally, after one last bump, the ridge widens and the summit appears, vast and welcoming. Welcome to 4810m!
Day 5
Back in the valley
- Activity Mountaineering
- Duration of the activity 6h
- Negative elevation 1200 m
- Exposed passages Yes
- Breakfast included
- Lunch not included
- Dinner not included
The descent follows the same route back to the Nid d'Aigle. We then board the Mont Blanc Tramway. Return to Les Houches by cable car, where we meet our vehicles. Lunch will be either in Bellevue or Chamonix.
Day 6

Note

Above 4,000 meters, wind or bad weather often makes the ascent impossible or too dangerous. We try to anticipate these factors as best we can and make the best decisions to help you reach the summit. The high-mountain guide accompanying you knows Mont Blanc intimately and will be best placed to assess the feasibility of the climb. Ultimately, they will decide whether or not to continue the ascent. For this course, we confirm the possibility of attempting the climb three days before departure. However, it is possible that the weather may ultimately be different from what was forecast (a frequent occurrence in Chamonix). In this case, the guide may still decide to modify the program or cancel the attempt on the morning of departure.

Since the summer of 2021, all reservations at the mountain huts on the normal route of Mont Blanc (Tête Rousse Hut and Goûter Hut) are mandatory and non-transferable for the ascent. Reservations open at the end of the year for the following summer. Therefore, we register participants subject to availability at the Tête Rousse and Goûter Huts when their reservations open.

Accommodation

🏔️ Mountain refuge - Days 1 to 5

You will be sleeping in dormitories in the mountain huts and the guesthouse. Blankets are provided; you should bring a sleeping bag liner. Slippers are available, so there is no need to bring shoes for the hut.

Our two guides (Philippe and Olivier) were fantastic in building our confidence during this course. After three days of acclimatization in Gran Paradiso (Italy), Mont Blanc was magnificent and revealed itself to us under its most beautiful sun! A magical trip, but one that requires serious physical preparation beforehand to fully enjoy the experience!
