Testimonials For ISM

​Hi Eira! It is Maite from Spain again! Just a message to tell you that I spent a wonderful week and that both guides (Paolo and Christian) were superb.

“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.

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!
