Highly recommend the OPAC course! 4 very days of very instructive and efficient teaching from George. My skiing and avalanche knowledge have greatly improved thanks to his program, including skiing technique in the morning and avalanche focused, on the ground exercises and observation in the afternoon. There’s a before and after this course for me. Allez-y les yeux fermés. Merci George!

Thoroughly recommend the OPAC course with George. It helps provide the necessary foundations for off piste skiing/avalanche safety. The online course complements the in person sessions very well, and is both informative and engaging at the same time. Cheers George!

We recommend you stay in accommodation in Morzine, near the bus route, for this course. From there we can access the mountains either via Prodains, Ardents or l'érigne (vallee de la manche). If we have enough vehicles within the group we may also use them. Let us know if you wish to stay in accommodation in Avoriaz, as this can also work.

Before and during your course you will be invited to a group whatsapp chat with the instructor and other group members.

course content

The course is made up of a pre-study component and 4 full days in the mountains (6.5 hours per day)

The practical component includes 4 x 2.5hr sessions of ski tuition & guiding time each morning (10 hours total). This may be on or off piste, depending on the current conditions and goals of group members. Expect to hone your skills on red, black and off-piste terrain and have a lot of fun whilst doing so. Video analysis will be offered where appropriate.

The avalanche training component closely mirrors the content & contact time of an AIARE 1 course (although this is not an AIARE 1), and is made up of 5 hours of pre-study work followed by 4 x 3.75hr practical training sessions in the field. If you would like to compare different avalanche courses such as AIARE or AST courses, please see our article on this here.

Practical Sessions:

Session 1: Companion Rescue Skills in avalanche response

Session 2: Avalanche Terrain - identification & analysis 

Session 3: Field Observation skills - formal and informal tests and tools for monitoring snowpack and red flags. 

Session 4: Companion Rescue follow up session

You can also expect a daily review of the Avalanche bulletin to learn how to understand and apply. 

We will practise risk management tools such as trailhead checks and cover group management and safe travel protcols. 

The pre-study online course, made up of tutorial videos, practical tasks and quizzes, will cover 10 lessons in off-piste snowsport safety:

1) Avalanche awareness

2) Off-Piste Equipment

3) Avalanche Terrain Analysis

4) Mountain Weather & Forecasting

5) The Avalanche Bulletin

6) Mapping & Route Planning

The course content will be the same for both the lift-accessed and ski-touring courses. Attendees on the ski-touring courses will still need to purchase a lift-pass, but having touring equipment will give us greater freedom and opportunity to access suitable terrain.
