IMPORTANT: Due to the unpredictable logistical challenges related to the Covid-19 situation, and our desire to offer high quality, safe experiences for all our clients, we have decided to only take personal booking requests for the 2020/21 ski season, and will therefore not be organizing any pre-scheduled courses. Thanks for you patience.

Please contact us if interested in guiding or courses for you or your group!

About Us


Our main services are centered around avalanche courses and snow science. We offer a variety of set courses at all levels covering avalanche awareness, snowpack assessment, and backcountry first aid. Many of our courses, particularly at the beginner level, also incorporate skills in ski technique and the use of a variety of backcountry tools and equipment. Our courses focus on practical skills, spending as much time as possible outside in the backcountry environment where we believe the best learning takes place. Our courses are generally held in the Trollheimen and Sunndalsøra mountains of central Norway. However, we do also offer custom courses and occasionally organize or participate in courses in other areas. 

Our instructors, Bastien Dupuy and Daniel Weiss, have over 30 years of skiing and climbing experience in alpine environments. This experience ranges from competitive alpine racing at the international level, to alpine climbing in Europe and North America, to backcountry skiing experience in Europe, Asia, and North America. They also hold extensive experience with wilderness first aid and rescue as well as many years of combined experience leading and instructing in various settings. Both hold advanced avalanche certifications from the American Institute for Avalanche Research and Education.
