Join me on this 1-day mountaineering expedition in the Arête des Cosmiques. And discover one of the most stunning climbing routes in the Mont Blanc Massif (4,808m).

Arête des Cosmiques, or Cosmiques Ridge, is a very popular mountaineering route in the Mont Blanc. And there are many reasons for its popularity! It stands between the border of Italy and France, and it is the perfect ascent for climbers that wish to gain confidence and tackle bigger ascents. Also, it offers the perfect mixed terrain, so that even expert mountaineers can challenge themselves here.

Due to its unique varied terrain, it’s also the ideal introduction to mixed climbing, as we’ll cross different patches of snow and rock. Also, this route is rated as AD – Assez Difficile or Fairly Hard. But sometimes it even reaches a PD or PD+ rate. Hence, it requires some climbing experience, especially abseiling skills. Therefore, I will be there for you making sure you are safe and giving you pointers so you can improve your techniques.

Then as we ascend, we’ll start getting better and more breathtaking views of all the surrounding peaks, such as the Aiguille du Midi. The dazzling sceneries we’ll enjoy all through our our journey, make this one of my favorite places to climb!

We’ll climb most of the ridge together. But there is a crux section that will require a belay. So be prepared for this challenge

If you are up for this challenge, don’t hesitate and send me a request. It will be an unforgettable expedition!

About the guide

I like the freedom and all the differents possibilities that it brings us. The mountain is a wide place to play each seasons and we will discover it together.

After few years at the ski club, I started the world competitions with the French ice climbing team for 6 years. I joined two years ago the french alpine team and started the formation of mountain guide behind my studies and my job at Petzl company. I live in the hearth of the French Alps in Chambéry so I am closed to each famous massifs, like Chamonix or les Écrins.

Antonin is an excellent guide! He knows Tignes  and Val d'Iser resort very well! Despite the fact that snow conditions were not very good, we did a number of great off-piste rides during the day



January, 2019

The day spent with Antonin was remembered to us by dynamism, interesting lines of descents. We had the opportunity to ride in different parts of the resort, open new freeride spots. In this regard, we felt that the guide ensures our safety and is guided by common sense when choosing a line of descent. In the next visit we will gladly use the services of this guide
