Can I please make the argument that everything closed down on Monday August 31 and
will reopen on December 5 ?
Aquamotion is very very closed, so are all the skilifts, via ferratas, mountain bike parks/trails and the hiking trails as it's been heavily snowing above 2.000 m for one week.
I have to drive up there on Thursday to meet two French skaters and we'll be lucky if we find a bar or "boulangerie" to go and have coffee. I'm planning to bring my hot drinks and my food as the only grocery store open has very short opening hours

I'm used to visit Courchevel at all times of years and I promise you it's a
real ghost town up there in the spring and fall!
