Testimonials For ISM

Summiting Mont Blanc was an important milestone for me which I am grateful to all at ISM. Particularly Terry, who is the ultimate professional never compromising on safety. Max is a pure gem with wonderful guidance and outstanding people skills in abundance.Altogether a brilliant week!

David (2017)

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 (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.
