Thanks @Robin Putnam .... I looks like seriouslyl off piste, Carte Neige is probably wise. I got the following information off the web : "Carré Neige explicitly covers: Off-piste skiing accessible from the ski lifts, provided you have a valid lift pass. - Search and rescue / piste rescue - Medical transport and assistance. - It costs €3.50 per person per day. - The policy has an overall €50,000 limit and a €50 excess on covered claims. So, if you're doing normal lift-accessed off-piste in Tignes, Carré Neige is a straightforward option." @Jocelyn Cockle on that basis, is Carre Neige good enough for your 1/1 course in January ?
