ISM offers an extensive range of both instructional and guided climbing courses as well as bespoke custom and private guiding packages.


Our instructional courses begin with the Summits and Skills 4000m course which gives participants a great introduction to alpine mountaineering and builds a foundation of skills that will last a lifetime. Once you've learned the basics of alpine mountaineering and developed those skills further we offer our Classic AlpinISM course. This is a natural continuation, developing your skills even more and coaching you to become more independent. Our Technical AlpinISM course is for those who have developed to a stage where they feel confident and have the experience to lead climb to a higher level and want to become totally independent. On completion of each of these summer courses you will receive a certificate showing the level you have achieved.

Our guided climbing courses sit alongside our instructional courses and give participants the experiences they need to develop and become a more experienced mountaineer. You wll still be taught and coached during these weeks but the emphasis is more on being guided up peaks and routes, gaining alpine experience. Our guided climbing courses can also stand alone so that you can enjoy a great holiday climbing routes and peaks at a standard appropriate for you. We also offer Classic guided weeks at a level appropriate for those who have completed our Summits and Skills 4000m course or other introduction to alpine mountaineering course or who have experience winter walking or scrambling in Scotland. Our technical guided weeks are for those wishing to build on their mountaineering experience and who have completed our Classic AlpinISM instructional course and wish to become more independent. The course is also suitable for those with a good level of fitness, ability and experience and want to get out and climb some technical peaks or routes.

With our experience and knowledge of the Alps we offer a bespoke service to help you organise a custom package for your group.

Over the last 20 years, we have worked very closely with numerous colleges, universities, schools and friendship groups to help make a trip of a lifetime happen. These custom courses are fantastic for groups which have time constraints or particular objectives.

Private guiding is for those who have specific technical objectives in mind or for people who want to really maximise their time and want the course to be totally tailored to themselves, their level of ability and at their own pace of learning and development. Private guiding can be arranged for one person through to teams of up to 3 friends who want something a bit different.

We hope you find something in our programme tthat inspires you for this coming season. If you need further information or wish to discuss your ideas please contact the ISM office and we'll be very happy to help.
