I'm off to Switzerland in three weeks. Great places are:
Gruyeres -- lovely grass strip, near the castle and the cheese-making factory. Nice cafe, lovely sun terrace, friendly people, Bucker Jungmann for hire and a Piper Cub too.
Saanen -- spectacular location, great place to stay for a couple of days and explore the mountains. Tarmac, 3000 feet long, 3000 feet high, an interesting downwind leg! Just up the valley from Gruyeres.
