Testimonials For ISM

What an incredible week learning the basics of Mountaineering. The course is perfectly balanced between summiting high alpine peaks and learning rope, climbing and glacier skills.Summits & Skills 4000 2026

Summits & Skills 4000m (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.
