    The Snow Training (ST) 1 is the first module of the ISTA (International Snow Training Academy) certification.

    Myself and some of my teammates, mountain guides and leader, are ISTA instructors. The objectives of the training is to work on the prevention and the management of risks linked to the practice of outdoor activities in the snow.

    Avalanches are not a twist of fate. Practitioners change, habits change – despite the wide range of rescue gear available, risks related to avalanches don’t change! True education can safe your life and that of others.

    ISTA’s training program is intended for the general public and is delivered by affiliated instructors (ski teachers and mountain guides). The goal is not to provide extra equipment, but rather the knowledge and skills required to assess and prevent risk. ISTA is innovative in that it offers a concrete, unique and unmatched response to the need for increased safety in the mountains.

    You have the gear – now boost your skills!

    The ST 1 training lasts for 2 days. The aim is to master the risk management processes, the procedures and the analytical tools.

    You’ll quickly notice the large amount of required learnings and your lack of knowledge in this field. You’ll acquire and apply the fundamentals, learn the basic words using an adapted terminology. You’ll be placed in a zone where you will feel confident, in order to better discover the complexity of the all approach and to give you the desire of getting forward.

    Here is the 2-day program:

    Day 1
    This first day happens as if you were having an usual day in the mountains. From the first contact till the debriefing at the end of the day, the adherent will easily follow all the steps of the story that he will be told.

    In the morning, we will learn about the methodology, the individual, his environment and the risk’s factors linked to them.

    In the afternoon, we will learn about assessing the risks, identifying the favorable terrains, understanding the communication rules and the way to move.

    Day 2
    The second day happens as the first one in order for you to assimilate the risk management process and strengthen your first learnings. Some topics will be reviewed, others will be further developed and some new ones will enlarge your knowledge.

    Join us and improve your knowledge linked to the risk management processes related to outdoor activities in the snow. These will allow you to enjoy even more your next skiing and mountaineering trips. We will soon fix the dates of the next training.

    About the Guide


    Attracted by the mountains since childhood, I started with climbing and alpinism. I then discovered my passion for ski touring.
    I started a Young&Sport instructor training to lead young people in the mountain, accompanied by guides. This experience inspired me to become a mountain guide, and I got certified in September 2015.
    I work in a guide's office with other guides friends as Stéphane, Raphael, Christian and Jean-Luc, mountain leader.
    What I love the most: make people enjoy, allow them to discover a region, laughing, everything in a safe way.
    So if there's something you wish, if you dream of exploring a region or country, don't hesitate to contact me.
    See you soon for new discoveries!

    What People are Saying about Yann Decaillet


    Yann was a fantastic guide for the last 3 days in Verbier. He was flexible and really listened to what we wanted, which was fun and adventure but not too hard core. Our teenage children enjoyed the experience very much. We covered most of the resort and enjoyed some off-piste touring as well and we felt safe and informed the entire time.

    Yann is a Young, Energetic and Experienced mountain guide. We have been Touring for 4 days in the Jungfrau Region with very mixed weather conditions. Yann showed me his abilities to lead under very tough weather conditions. Although always looking for Adventure and Challenges, even under the tough weather conditions, he proved his experienced as a guide and knowledge of the region. Safety is always first and from there we strive for our limits. We had an amazing 4-days and future adventures with Yann have already been discussed! Definitely the guide i want to rely on high up the mountains!
