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 (Instructional Course)

Thanks for a great week, in some pretty challenging and extreme conditions. Thanks for keeping us safe, teaching us loads, and being all round fantastic fun. I'd look forward to coming on another trip with you guiding.

Steve

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.
