Anyone French / Swiss on here who has been riding in the Alps?

A mum & dad of a friend went to somewhere in Switzerland recently and they
could go in cable cars / ski lifts and walk down mountains. Now, not that
I’m the sort to chicken out of riding up mountains, oh no, not at all, but
my mate who rides a bike is definately of that inclination and it does
sound like wicked fun, a whole week of quite difficult downhill without
any of the uphill. Apparently the lift passes are quite cheap in the
summer when there isn’t any snow and you are allowed to take bikes up.

I saw a picture somewhere of a french muni rider, so I know they exist?
Anyone out there?
