Our highly qualified experienced instructors will develop your knowledge of all aspects of the winter environment through both practical application on the mountains and some short technical lectures. As always, the skills of navigating will form an integral part of each day’s activities.

The Objectives 

The International Mountain Leader scheme (IML) provides comprehensive training and assessment for individuals who aspire to work as leaders in Europe and further afield. It integrates training, experience and assessment in a variety of realistic situations. The scheme provides training and assessment in the skills required for leading and educating groups worldwide in summer conditions and also on easy snow-covered, rolling, Nordic-type terrain in the “middle mountains” in winter conditions. The scheme does not involve the techniques and equipment of mountaineering, alpinism or glacial travel.
