Week-end in the Vallée Blanche

The Vallée Blanche is one of the most beautiful and famous off-piste ski run in the world. It is located in the French Alps and is a fantastic 22-kilometer-long ski descent. In fact, it’s one of the longest in the world! 

This exciting 2-day trip starts in Chamonix, at the Aiguille du Midi cable car station. When at 3842m, your specialized guide will show you the amazing view of the Mont Blanc massif. You then descend the Aiguille du Midi snow ridge roped up with the guide and start your run from the easiest way, in order to enjoy the breathtaking landscapes peacefully. After a rewarded lunch break with a fantastic view, you descend the Mer de Glace before reaching Chamonix by the famous skiable path running in the forest. On the second day of this weekend, you will discover a wilder route to descend the Vallée Blanche. You will navigate between seracs and crevasses, heaps of fun! During all the descents, our guides will ensure your safety and open the way. They will also teach you the secrets of off-piste skiing. You will end the weekend, sad to leave but happy to have lived this amazing experience!


  • Day 1 Discovering the Vallée Blanche

    We meet with our expert guide at 9 am at the Aiguille du Midi cable car station. He will check our equipment before taking the cable car. Up there, we discover one of the most beautiful panoramas of the Alps. The biggest peaks of the massif seem to be very close: Mont Blanc, Dent du Géant, Grandes Jorasses, Aiguille Verte...
    We descend the Aiguille du Midi snow ridge roped up with the guide and begin our classic route run (few difficulties but magnificent scenery: Gervasutti eperon, Mont Blanc du Tacul). The guide always goes first to ensure our safety. When passing through the seracs of the Glacier du Géant, we have to be extremely careful and do precisely what the guide tells us. This requires a good ski control. Just after this passage, we will take time to eat our packed lunch and drink a warm tea! We then reach the flat surface of the Mer de Glace glacier. We have to ascend a steep 100m rocky slope to reach the skiable path which will get us back to Chamonix. If there is not enough snow, we will go back by the Montenvers railway station.

  • Day 2 Second itinerary in the Vallée Blanche

    Today is an ambitious adventure day in high mountain!
    After a good breakfast, we leave to the Aiguille du Midi cable car at 10 am (or earlier if conditions require it). We put our skis back on up there and descend through more secret off-piste routes (e.g. Petit Envers or Grand Envers route) chosen by the guide, such delightful runs! Sometimes we will ski really close to the crevices, so we must carefully follow the guide's way. We will probably be back in Chamonix around 4pm to say goodbye.

Budget & exchange

France is in the Eurozone. Therefore, the unit of the currency is the Euro.

Credit cards and debit cards are very useful for cash advances (but don’t forget to bring your PIN number!). 
ATMs are available in Chamonix, but there are no guarantees that your credit card will actually work in France.  It is best to bring cash, just in case!
Be aware of the fees usually applied when purchasing products or services on a credit card. 

Always take more rather than less, as you don’t want to spend your trip constantly feeling short on funds. As currency exchange rates can often fluctuate, we recommend to check the following website for daily exchange rates: https://www.xe.com/


Clients usually pay for the guides’ drinks : you might find it practical to make a group kitty at the beginning of your stay (no obligation).

Health information & recommendations

It is important to consult your doctor for medical travel information well before departure. We recommend that you carry a First Aid kit as well as any personal medical requirements. 
Please keep in mind that we are often in remote areas, away from medical facilities. Please carefully read the brochure and itinerary when selecting your trip, to make sure our style of travel suits you. 
Please note you will travel to high altitude. Most people can travel to 2 500m with minimal effects. However, everyone reacts differently to altitude and altitude sickness can occur. 
For details on how to best prepare your trip please consult your physician. 


The weather in the French Alps varies up and down the mountain chain. It is a mountainous region between 800 and 4000 meters, so altitude plays a big part in the local weather. 
As you climb higher into the mountains it gets 1 degree cooler every 100 meters. It is the case all year around but other factors such as temperature inversions and winds influence the climate.  The sun plays a very important role too. In the winter, when the sun is lower in the sky, some lower or north facing valleys are blocked from the sun by mountains for a large part of the day and are colder.  

Spring can be a bit unpredictable : rain, sometimes even some snow interspersed with hot sunny days. 
It can be quite hot in summer: around 20 to 30 degrees, but the fresh mountain air cools you down during your hike. 
In autumn, temperatures start to cool down, but it is still perfect conditions for a walking holiday.  
During winter time, the higher you get, the more snow you will see. Snow usually starts to fall in November and stays until April. 

Keep in mind that weather conditions are unpredictable. Therefore, the trip organization can me modified for your safety. 


There will, of course, be electricity in Chamonix. If you are scared to run low on battery, we advise to bring an external battery charger.  
Power plugs in France have the particularity of being male and female at the same time : they have 2 prongs and a receptacle. If you need an adapter, please purchase if before departure.
In France the power plugs and sockets are of type E. The standard voltage is 230 V and the standard frequency is 50 Hz.

Local time

France is in the Central European Time Zone. Central European Standard Time (CET) is 1 hour ahead of Greenwich Mean Time (GMT+1).

Like most states in Europe, Summer Time (Daylight-Saving) is observed in France, where the time is shifted forward by 1 hour; 2 hours ahead of Greenwich Mean Time (GMT+2). After the summer months, the time in France is shifted back by 1 hour to Central European Time (CET or GMT+1).

Our aim is to allow visitors to discover the many facets of France by taking you off the beaten path and getting you in touch with its nature and residents, while ensuring that your visits do not have a negative effect on its natural environment and people.

  • Most of our accommodations are run by locals, thus ensuring that the largest part of the revenue generated through your trip will stay within the region.
  • France is known for its exquisite cuisine. The art of cooking and the joy of eating are part of everyday life. Each region has its particular foods and flavors which we would like you to explore and appreciate.

Guide's advice

The Vallée Blanche offers a unique opportunity of skiing in high altitude. But since we are not on ski slopes, we must be extremely careful. My work is to show you the way and guarantee your safety !

Required level

You must have an excellent ski level (red/black tracks) and a good experience in off-piste skiing (not compulsory). There are many challenging variations of routes down the Vallée Blanche and you must have a good ski control : you have to follow the exact guide’s marks.
