Terry Ralphs

IFMGA British Mountain Guide

Terry learnt to climb on the gritstone edges of the Peak District then after graduating from Leeds University he decided to make his living in the outdoors, moving to North Wales to work at Plas y Brenin before guiding in the Himalaya leading treks and trekking peak expeditions.

Now based in Leysin, Terry now guides through the winter, spring and summer in the Alps and loves the changes of activity that each season brings. He feels that the wide-ranging programme of ISM gives him variety in his guiding work that would be difficult to find elsewhere. In his free time he remains a dedicated enthusiastic climber with a penchant for long and sustained rock routes such as those in Yosemite and Spain. He has a craftsmanlike approach to his climbing with a precise and controlled technique – whether on ice or rock you can learn a lot just by watching him climb.

Testimonials For ISM

Thanks for organising an excellent week. The course format & accommodation was perfect. The guide was outstanding & gave us a full week of constructive tuition. I was able to put this training into practice the following week when I met up with a friend.Classic AlpinISM 2026

Thanks for a fantastic week. It was really one of the best things I have ever done. I learned a lot during the week, not only about climbing technique, but also about attitude.
