The ISM Team
In the early sixties an ex-fighter pilot named John Harlin lived and worked in Leysin at the American College of Switzerland. A very determined and charismatic mountaineer, he was eventually joined there by Royal Robbins. Leysin became the 'basecamp' for leading American and British alpinists of the day, such as Gary Hemming, Layton Kor, Dougal Haston and Don Whillans. They began exploring the Leysin Tours (limestone towers above Leysin up to 500ft high) and many of the classic routes bear their names.
At that time there were still 'last great problems' to be solved in the Alps. The South face of the Fou was unclimbed and there were no 'Directissimas' on the Dru West Face or the Eiger Nordwand. With Robbins, Harlin succeeded on the first two objectives; then in 1965 he made another far-reaching contribution to mountaineering by founding ISM.Read More

Summits & Skills 4000m (Instructional Course)
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!
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.
