Testimonials For ISM

Perfectly paced and tailored, great variety of skills learned. Guiding and Instruction? Thomas was fab! Everything was pitched at the right level (no pun intended), safety was always paramount and everyone had so much fun learning everything.

Clare
Summits & Skills 4000m (Instructional Course)

​Good mixture of progressive instruction and learning, climbing and guiding. We climbed some very good mountains from good huts and made the best of the mixed weather conditions. The course also used a range of situations and locations to cover a wide range of skills and techniques.

Donald Connolly
Classic AlpinISM (Instructional Course)

“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.
