Testimonials For ISM

​Hi Eira! It is Maite from Spain again! Just a message to tell you that I spent a wonderful week and that both guides (Paolo and Christian) were superb.

Thank you very much for an enjoyable and inspiring week in the Alps, and for your patience and good humour throughout. You have a completely satisfied customer and I hope to join another ISM course sometime in the future.

Michael Firth
Classic AlpinISM (Instructional Course)

The course was excellent, lots of variety and provided me with a good range of skills. Loved reaching the summit of the Weissmeis, for such a nervous and unconfident novice like me, I gained a real sense of achievement from the ascent and the whole week. Huge thanks to Pat.
