If you hurt yourself and require medical attention on the mountain, it can cost you a lot of money! For example, the rescue costs if you injure your knee in Italy, including transport in a stretcher to the doctor's surgery in La Rosière, costs around €600. Even if you are covered by your credit/debit card insurance, you will have to pay the costs up front. We recommend taking out Carré Neige insurance when you buy your lift pass.

It covers the costs of search, rescue, transport, treatment and repatriation, plus the partial refund of unused ski lessons and unused lift passes. Info and conditions here.
