Testimonials For ISM

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)

Thank for an amazing couple of weeks! Matt and Stu were fantastic. I learned so much but also had a lot of fun. I have come home feeling like a proper mountaineer, having made some great new friends and with some unforgettable memories. I plan to come back next year!

Tim

​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.
