Last year
Sion (LSGS) won PrivateFly's most scenic airport approach from the flight deck.
BBC Coverage Daily Mail.
I like Samedan better than Sion, particularly in winter. Other nice ones are Chambery, Saanen, Innsbruck.
I like going to Olbia also, though that is more because of the "scenery" in dark blue pencil skirts in the FBO.
