Testimonials For ISM

Brilliant!! I was a walker at the start of the week. By the end had been on glaciers and climbed a 4000m peak!! It was a wonderful, wonderful, experience which i will never forget. It was excellent value for money and I hope to be joining you for years to come.

Ian Twizell
Summits & Skills 4000m (Instructional Course)

Terry was a wonderful guide and made everything fun, laid-back and an overall good experience. I would be happy to ski or climb with him again. All the logistics in Leysin and in Italy went smoothly. A really nice time.

KL (2017)

"I loved the course and Terry was great. I learned a lot and had a lot of fun and feel confident and secure in my technique".
