    See France, Italy, and Switzerland from the top of one glorious peak! Enjoy a mountaineering day program to the summit of Aiguille du Midi and traverse the Cosmiques Ridge!

    At 3,842 meters high, Aiguille du Midi has long been a fixture in the Mont Blanc massif of the Graian Alps. From this height and with unbelievable panoramic views, it is easy to make out Mont Blanc (4,810m) and the surrounding regions of the Alps. Its summit can even be reached via cable car directly from Chamonix, making it a popular destination for tourists.

    For mountaineers and adventurers, one of the most appealing aspects of the mountain is the Cosmiques Ridge. This popular climbing route offers every aspect of an ideal mountaineering program, including rock and ice that will test abseiling and mixed climbing skills from a picturesque peak. The views from the ridge make the climb extraordinary.

    Our program will put you at the center of the incredible alpine wonderland of Cosmiques. Its easy access allows us to complete our program safely within a day, and you will never be without some of the world´s best mountain scenery. It provides a great mix of history, beauty, and action for thrilling climbs and non-stop fun.

    The first ascent through Cosmiques Ridge was in 1911, and it has been a significant traversing route ever since. It is not considerably difficult to complete, though the season and the weather can provide additional changes. It is a great route for those climbers without substantial experience, but you should be in good shape to undertake the program.

    This area is my home, and I would be delighted to share it with you. I can show you the little things that will make this trip one in a million. My guiding expertise will enhance your trip and you will see the ins and outs of this magnificent ridge like a local. It is a perfect program for anyone interested in gaining valuable climbing experience and taking your mountaineering skills to the next level.

    Book this trip now! Experience a day climbing over the Cosmiques Ridge of Aiguille du Midi and a mountaineering program for the ages!

    I can also guide you on a two-day ascent of Mont Blanc Trois Monts!

    About the Guide


    I'm an IFMGA guide from Romania and a member of the Eastern European Mountain Guide Association.

    With two decades and a half spent doing mountain sports and nearly a decade guiding or teaching climbing my work and passion has taken me from the mountains and crags near home to the greater ranges.

    Please feel free to get in touch for trips involving trekking, climbing, skiing or expeditions. I also run climbing courses (rock, ice, mixed and alpine), ski touring and winter safety workshops as well as self rescue in vertical terrain clinics.

    Regular climbs from sport to multi-pitch and alpine terrain are charged on per-day rates plus expenses while expeditions are charged on a flat rate based on the size of the group and the destination.

    I have a very strict policy on guide-to-guest ratios for all types of terrain and these are clearly explained prior to engagement. For multi pitch climbs it is usually 1:1 and it never exceeds 1:2. For single pitch venues (especially on instructional outings) it never exceeds 1:4. Higher ratios are possible with the hiring of additional guides and only following prior arrangements. For treks and ski tours the ratios are more generous but depending on the terrain and/or the group’s experience.

    I am comfortable in using for guiding purposes the following languages: English, Romanian, French and Italian and for teaching purposes English and Romanian.

    We had a great time , unfortunately Cosmin broke his arm two weeks before the trip but the replacement guide Nicu Durnac was superb.

    The plan was to leave early to ascent Mont Blanc via Trois Monts. As a beginner, Cosmin accessed my performance by timing my ascent to the shoulder of Tacul, else he has to change the plan. I met the timing and proceeded to Maudit. Unfortunately, he made a tough decision to head back as the condition at the foot of Maudit was not great. (We heard serac fell at mid day). Being professional, Cosmin changed the plan to ascent Tacul and we did Cosmique Arete. I would highly recommend this trip!
