Testimonials For ISM

What a brilliant week we had! I really enjoyed the fact that the course was very hands on and we were given freedom and responsibility to look after ourselves. I really like the fact that the price was all-inclusive, the the course was excellent value for money!

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)

Thanks for a great week, in some pretty challenging and extreme conditions. Thanks for keeping us safe, teaching us loads, and being all round fantastic fun. I'd look forward to coming on another trip with you guiding.
