Testimonials For ISM

The course content was brilliant. No knocking whatsoever. We had Jacky for the duration, and his experience shines through and his leadership. He taught me a lot of things, not just the black and white of things but actually quick methods to overcome tricky situations!

Andy Challenor
Summits & Skills 4000m (Instructional Course)

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!

Mont Blanc Ascent

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.
