Have flown into/from meribel altiport, next valley along from courcheval, just by turning up and asking the local flying club there, flight took in a low pass over courcheval. I understand that you need a special rating on your licence to fly in solo , remember a "pilot " magazine article a few years ago , a guy took his 182(I think) over there and met an instructor at Chambery and thence up to courcheval. Obviously you need a good performance aircraft !
