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.

William 2021

The course was excellent, lots of variety and provided me with a good range of skills. Loved reaching the summit of the Weissmeis, 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 to Pat.

Summits & Skills 4000m (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.
