Testimonials For ISM

Brilliant!! I was a walker at the start of the week. By the end had been on glaciers and climbed a 4000m peak!! It was a wonderful, wonderful, experience which i will never forget. It was excellent value for money and I hope to be joining you for years to come.Summits & Skills 4000m 2026

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!Summits & Skills 4000m 2026

The Classic Alpinism course last week was excellent! The itinerary was really well planned taking into account the less than perfect weather and the abilities and aspirations of the group - we all learned loads.Classic AlpinISM 2026
