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.Classic AlpinISM 2025

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 4000m peak 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.
