Enjoy the green meadows of Pormenaz before spending the night in a bivouac under the stars, with the Mont Blanc as a backdrop. Back to basics, simplicity and sharing will be the key words of this winter escape!

Thanks to our partner Samaya, all the bivouac equipment is at your disposal to keep you warm and to make the most of this extraordinary night.


Day 1: Buet - Vallon de Villy
We reach the village of Buet by train, the starting point of our hike. From there, we follow the water up the superb Bérard valley towards the Col de Salenton (2,526m). We enter the kingdom of the ibex and vulture. At the crossroads of three natural reserves, between crystalline and sedimentary rocks, we are offered a sublime landscape. We continue through the wild valley of Villy towards the refuge of Moëde Anterne and then to the lake of Pormenaz (1 845m), the perfect place for our bivouac. Respecting the flora and fauna, each in our own tent, we will spend the night in this idyllic setting facing the Mont Blanc.
Elevation gain : 1 200m - Elevation drop : 700m

Day 2: Vallon de Villy - Servoz
We break camp in the early morning to cross the Pormenaz plateau. This historic, suspended pasture in the Chamonix valley faces the Mont-Blanc with all the magnificent views that you would expect. We will have a chance to meet the shepherd working in this beautiful site before descending towards Servoz, a typical and unspoiled village in the Chamonix valley. We will arrive in the afternoon at Servoz train station where we will take the public transport back to Chamonix.

We recommend that you take particular care in choosing your equipment because it greatly contributes to the success of your stay. As alpine climatic conditions can be very variable with sudden changes, it can get very cold very quickly at altitude, it is better to stack thin layers rather than having one big piece of clothing. It is not uncommon to have snow in the middle of summer, do not skip warm clothes, even if the weather seems favourable. Conversely, the sun can be scorching hot. Without weighing it down, you should always have enough in your backpack to deal with capricious and severe weather.

- A backpack with a capacity of at least 40 litres (better too big than too small). Make sure you have enough space for the picnic. A small tip in case it rains : even if you have a backpack cover, always protect your belongings in a plastic bag (a big rubbish bag) inside your backpack. Your bag should not exceed 9 kg.
- A pair of high-top hiking boots with Vibram soles. For new shoes, make them fit your foot first by wearing them front. If you are prone to blisters: talcum powder applied to dry feet and in the shoe in the morning.

For more comfort regarding underwear (T-shirts, boxers, socks), avoid cotton which is heavy, cold and dries very slowly. Opt for synthetic technical textiles, or wool, which is making a comeback. They are hotter and dry very quickly.
