Go to the engadine, or the alpes vaudoise, or even the bernese
oberland. There's either the zone in the west (around Gstaad) or
the east (around Interlaken). You'll have a hard choice which
valley you want to visit (with the villages Zweisimmen, Frutigen,
Kandersteg, Meiringen).
Engadin, Alpes Vaudoises or the Wallis would be fine, too.
