Come climb Arête des Cosmiques with local IFMGA-certified guide Benjamin. It is a classic that every mountaineer should try at least once!

Not specified


1/2 Day

Jun, Jul, Aug, Sep



Join me on this guided climb to the Arête des Cosmiques summit and discover the high mountain in this beautiful area!

The Arête des Cosmiques is one of the classic climbs in the Chamonix area. It is the perfect introduction to mixed climbing (snow and rock) but requires some mountaineering experience. The route is rated AD (Assez Difficile/Fairly Hard) but you’ll find the crux is quite hard for its rating. It requires some suitable mixed climbing and also abseiling skills.

As we climb up, we’ll enjoy magnificent views of the Aiguille du Midi and the surrounding peaks. This is one of the main reasons why I like to bring my clients to Arête des Cosmiques.

June to September are the best months to climb this route. However, the route can get really busy during these months so try to avoid weekends.

We will meet in Chamonix and take the Aiguille du Midi-Vallee Blanche Cable to the top. From there, we’ll go down to the Col du Midi and then to the Abri Simond hut, where the route starts. It is possible to reach the summit in the same morning.

If you’ve always dreamed of making it to the top of Arête des Cosmiques, contact me now and we’ll arrange the details together. I can guarantee an unforgettable experience!

About the guide

The Jura massif is an ideal place to learn and grow your experience in alpine techniques. I practice mountaineering, ski touring and ice climbing in the winter. I am also located very close to the Swiss and French alpine massifs.

First, I started as a ski rescuer. My passion for skiing and climbing helped me discover the classic routes in the mythical summits of the Alps. The first mountain courses I went on with friends as a guide - which I did with a lot of effort, doubts and perseverance - were much needed to build my experience. Still, they also gave me a lot of joy, and I was able to pursue them while laughing and creating beautiful moments shared.

My experience and terrain knowledge will allow you to move safely and enjoy your time, without a promise of the summit but of sharing a privileged and unique moment in the mountains.

Finally, I'm a fully certified IFMGA mountain guide.

A great day out exploring the off piste of the Portes de Soleil. Benjamin was friendly, professional and tailored the day to our needs perfectly. I would definitely recommend him as a mountain guide to help further your off piste and ski touring skills. He offers trips in the Portes de Soleil, Chamonix and Verbier. I’ll be looking him up for sure next year. Thanks Ben

An excellent guide, who planned an amazing route and combined technical instruction with local knowledge to provide a very enjoyable day of skiing that improved my off-piste skills and gave me confidence to try lines that I would never consider alone.

Experience extraordinaire. De belles sensations tout au long du parcours avec des paysages juste fantastiques. Journée conclue avec un apero avec les autres membres de l'équipe. Bonne organisation de Gauthier et de ses guides et belles rencontres avec les autres randonneurs.

Benjamin was our guide for a day out on Mer de Glacé. Great guide that provided useful insight in navigating the Glacier, proper techniques and even provided us an opportunity to rappel into a crevasse! Overall this was an absolutely amazing experience. I really liked how he would check in on us but was not at all overbearing. We felt like we had freedom to explore and poke around when he wasn’t giving us instruction. Just a heads up to anyone that doesn’t do heights, from the train we roped in together, climbed down a rock face approx 200m (about 650ft) on multiple steel ladders to the valley and then proceeded to hike up the glacier. I felt very secure and well supported by the group at all times. Bottom line of you are thinking about booking this experience and do not have the technical experience or equipment then I 100% recommend doing it. Will not disappoint

One week in a winter fairy tale. With a lot of fresh snow, freeriding all over the mountains, from top till the end of forests. Happy time to have such powder conditions like it was in our childhood...

Ben is a world class guide and my experience was so much fun. I would recommend him to any of my family or friends and will be back in the future and will request Ben.

Wow! I have dreamed about this vacation for 6 months and skiing the Valle Blanche was on the top of the wish list. What a killer day and a great guide

I am really, really happy with both Explore-share.com’s service and their recommendation of guide Benjamin Souflot. Benjamin was extremely personable, and more importantly knowledgeable. Benjamin recommended where to rent ski gear and the proper gear for the day. He had crampons for my boots, ropes and other safety gear needed. I showed up at the meeting spot early, and Benjamin was already there waiting. On the gondola ride up to Aiguille du Midi, he talked safety and what to expect. When we got up to the top, it was very windy and intimidating. As Benjamin prepared the gear for our descent, he talked safety, strategy and was reassuring that it would be a fun, safe adventure. As I look down the face of the Ridgeline, I became nervous and anxious. Benjamin was very reassuring that it was going to be OK, that I was safe with him and we would make it down. Sure enough, Benjamin literally “talked me off the ledge” and we proceeded down. Benjamin was focused & guided me the entire time. Once we started skiing, Benjamin gave great instructions as to where to ski, what to expect ahead, etc. He was very knowledgeable about the mountain. When we took breaks, Benjamin shared with me interesting facts about where we were, in the mountains France, Italy, Mount Blanc, the crevasses, various peaks, history of the glacier, etc. I had a great experience! I would definitely do this trip again with Benjamin. I would also recommend this trip to anyone else with Benjamin and your company, Explore-share.com. Thank you again! -John

While we were not able to take this itinerary due to inclement weather, our guide Benjamin still managed to take us through very interesting terrain perfectly suited to our abilities, and even adjusted his schedule to find some sunny days. My son and I had a great time and learned a lot. These will be memories for a life time. Thank you!

Ben is a great guide and did a wonderful job with our group. He's patient and worked very well with us. I'd highly recommend him to other groups.

We had booked Ben for a single day and weather did not play nice: rain in the valley, snowfall and high winds on the summits. Hence, we were locked down to a single slope. Ben still made this an awesome day with lots of off-piste dives wherever possible, some avalanche training in between and good advice and powder exercises as he's simply an excellent skier. On top of that he is a great person and also available as guide in Chamonix and 4Vallee. Full recommendation!

The trip was simply awesome. Benja is such a great mountain professional, It was a delight to walk along his side. I would definitely recommend both the man and the guide. He provided us with good tips and a good amount of material as well. His pricing practice is well fitted and super flexible. If you're still wondering whether you want to go or not, please help yourself and go for it! Kévin

Benjamin, jeune guide professionnel, confirme avec excellence que la valeur n’attend pas le nombre des années ! Nous avons pu, en sa discrète compagnie,  découvrir en toute sécurité une approche inédite et respectueuse de la montagne dans des randonnées en peau de phoque. Je me réjouis déjà de réitérer cette expérience l’année prochaine, si possible encore  avec le même guide, et avec même un degré de difficulté supérieur…



March, 2017

Malgré des conditions de neige médiocres notre guide Benjamin nous a permis de passer deux journées fantastiques à la découverte de sites vierges dans les Portes du Soleil.  La rando en peau de phoque fut pour nous une grande première à renouveler très rapidement.  Admirer la montagne avec un guide de qualité quoi de plus excitant dans la vie !!



March, 2017

Superbes moments passés ensemble dans les portes du Soleil, très sympa et très pro. Nous nous réjouissons de réitérer l’expérience du côté de Chamonix en ta compagnie.



March, 2017

Nous sommes partis 2 jours avec Benjamin. C’était fantastique de découvrir une autre façon de faire du ski. Benjamin est un gars super sympa et sécurisant. On a passé deux belles journées avec lui. Un regret : Que l’on ne découvre qu’à 54 balais la randonnée à ski. Qui sait !! On prendra peut-être goût à l’alpinisme à 70 ans. Merci à Explore-Share.com de nous avoir présenté Benjamin. Il est sûrement à conseiller à d’autres candidats.



January, 2017

Nous avons passé une excellente journée avec Benjamin sur le domaine des Portes du Soleil. Malgré des conditions d'enneigement difficiles, il est parvenu à nous trouver de belles descentes. Très pro et à l'écoute de nos envies, Benjamin nous a fait découvrir des recoins cachés dont il a le secret. De plus, ses conseils techniques en pente raide ont été très utiles. Entre des combes bien préservées, de la peau de phoque et une Via Ferrata avec les skis sur le dos, la journée a été remplie d'émotions. Je le recommande vivement !



February, 2016

Malgré le peu de neige et une station de Chamonix bien peuplée, Benjamin a réussi a nous trouver de chouettes itinéraires de rando, a l'écart des foules et au milieu d'une nature splendide. Ses bons conseils nous ont aussi été d'une grande aide lors de montées en peaux de phoques plus techniques. Très sympathique et posé, Ben est un guide de montagne que nous recommandons vivement!
