Testimonials For ISM

“What an incredible week learning the basics of Mountaineering. The course is perfectly balanced between summiting high alpine peaks and learning rope, climbing and glacier skills.

William 2021

I just wanted to thank you as well as Mark, our guide for the amazing week. The course was well organized and was just perfect for a beginner to mountaineering. We couldn't have wished for a better adventure. The memories are irreplaceable.

Summits & Skills 4000m (Instructional Course)

​Good mixture of progressive instruction and learning, climbing and guiding. We climbed some very good mountains from good huts and made the best of the mixed weather conditions. The course also used a range of situations and locations to cover a wide range of skills and techniques.
