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.

Matterhorn Ascent

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)

The classic alpinism course last week led by Swedish Daniel 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.
