Testimonials For ISM

Neil, our guide for the week, was exceptional; a true professional, a huge inspiration and just great company. He shared so many useful tips with us and had great stories to share too. Looking forward to booking another course with ISM in 2022!”

William Summits and Skills 4000m 2021

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)

This was a fantastic trip. Paolo was excellent. The accommodation great. All helped along by wall to wall sunshine, stunning arctic scenery and some superb snow, so no problems as far as I'm concerned.
