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

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!Summits & Skills 4000m 2026
