Testimonials For ISM

Thanks for organising an excellent week. The course format, accommodation and set up was perfect. The guide was outstanding and gave us a full week of constructive tuition. I was able to put his training into practice the following week when I met up with a friend and did the Cosmiques Arrete.

Classic AlpinISM (Instructional Course)

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

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.
