Testimonials For ISM

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.

Summits & Skills 4000m (Instructional Course)

The Classic Alpinism course last week was excellent! The itinerary was really well planned taking into account the less than perfect weather and the abilities and aspirations of the group - we all learned loads.Classic AlpinISM 2026

Chris Ward
Classic AlpinISM (Instructional Course)

Thanks for organising an excellent week. The course format & accommodation was perfect. The guide was outstanding & gave us a full week of constructive tuition. I was able to put this training into practice the following week when I met up with a friend.Classic AlpinISM 2026
