Testimonials For ISM

Our three guides were all excellent: Thomas, Phil and Paulo. I can't speak highly enough of them. They were all good company and superb climbers, and patient with us all.

Donald Connolly
Matterhorn Ascent

Neil, our guide for the week, was exceptional; a true professional, a huge inspiration and just great company. He shared so many useful tips with us and had great stories to share too. Looking forward to booking another course with ISM in 2022!”

William Summits and Skills 4000m 2021

What a brilliant week we had! I really enjoyed the fact that the course was very hands on and we were given freedom and responsibility to look after ourselves. I really like the fact that the price was all-inclusive, the the course was excellent value for money!
