See the Alps from the exposed Arete des Cosmiques on an exciting guided climb! Take a day to reach the top of one of the most popular mountaineering destinations in the Mont Blanc massif!

One of the best climbing destinations in the Alps is the Arete des Cosmiques. It boasts views of the mountainside surrounding the Mont Blanc massif, and is easily accessible from nearby Chamonix and Aiguille du Midi. Its mountaineering specifications include exposed ridges, mixed climbing, many routes suitable for every alpinist.

This region is home to some of world´s most notorious mountain views. While this peak features a rocky top with jagged spires, it looks out on the incredible surrounding summits. The panorama is arguably the best way to finish a climb, and makes this an unforgettable experience for every participant.

The climb has a reasonable approach that does not require substantial difficulty. You will have the opportunity to climb on snow, ice, and rock on your way to the summit, with some aspects of a technical ascent and lots to appreciate as you take in the peak.

The exposure of the Arete des Cosmiques gives the impression that you are on top of the world in every sense of the word. The summit is often reach by way of Aiguille du Midi and the cable car that travels to its peak. The charming features at every step of this program make it an all-encompassing Alpine experience that you can´t wait to do again.

This trip does provide some moderate climbing challenges, with different aspects of mountaineering skills. You should be in good shape for this intermediate trip, and have some previous mountaineering experience.

I will guide you in the ways of the Alps, and you will feel like a local when you descend from the mountain. My objective is to provide the safest and most enjoyable experience for you to take with you for the rest of your life. I am happy to provide a program that is designed for you and your skills to make the most of the program.

Head to the Arete des Cosmiques and book this day trip NOW! There isn´t a mountaineering experience quite as unforgettable as this one…

We can also climb the infamous Aiguille d´Entreves. Or we can head to Aiguille Rouges for a day (or more!) of rock climbing!

About the guide

I was born in 1990 in Lus la Croix Haute, a small village nestled between the Vercors and the Dévoluy, and right on the border of 3 French departments: Isere, Hautes Alpes and Drome.

I started practicing mountain sports at a very young age: skiing first and then then mountain biking. At the age of 7, I started ski touring on the trail just above my house with my father and my sister. And then, a few years later, I gave my first steps in ski mountaineering: Pelvoux traverse at 9, Dome de Miage on skis at 10 and the Meije traverse at 12.

I've always enjoyed competition and started competing in ski mountaineering since I was very young. I've won Pierra Menta twice and the World Championship four times.

Becoming a mountain guide has always been my dream and I'm very happy to see it come true. I have also started paragliding recently and I hope to be able to combine it with my mountain guiding business one day.

I currently live in St Nicolas de Véroce in Haute Savoie. My father's family comes from this village and it is here that I learned to ski. It holds a dear place in my heart and it is here that I feel most at home.

I was looking for a local guide for a hike I was planning and came across Explore-Share. They seemed to have good reviews and so decided to give them a try. The experience was very positive and completely happy with their service. I will be using them again for next trip.

Thank you explore-share for a wonderful via feratta experience. We have been wanting to learn for a long time but don't have the facilities in Scotland. The guide Mitja was extremely helpful and knowledgeable, answering all my many questions and providing advice. On the day head to take another group but he quickly arranged another guide Borut, who was brilliant. We had a fantastic morning learning via ferrata at Hvadnik in the gorge. It gave us the confidence to later hire our own equipment and go out in Mojstrana. Altogether a five star + experience. Thank you.

Hello! I have been thoroughly impressed by the service and assistance that explore-share have provided the past couple years in helping to plan my trip to the High Tatras in Poland. I really appreciated the flexibility that they provided in allowing me to rearrange my trip twice owing to covid. They were responsive and communicative throughout. This trip was part of my Stag weekend celebrations and explore-share connected me with an outstanding guide in the form of Marcel - he was an excellent recommendation and we really enjoyed our guided hike in the High Tatras with him. Marcel was an outstanding professional, placed a high focus on preparing well and staying safe, and was also a great guy! Highly recommend. Many thanks and best wishes - Richard
