Gruyeres is a must-see. By train, you can pick up the "small train" from Palezieux where Intercity trains stops from Lausanne/Berne. Gruyeres train station is at the bottom of the village but the walk up there is not too strenuous even for the unfit. The village is about as postcard pretty as it gets, medieval houses, castle, lovely vistas on the moutains. You can get your fix of fondue and meringues/double-creme, there is a small shop selling local products (and bare in mind you also have cured meats, cheese and chocolates producers just off the train station).

The castle is very well preserved, full of interesting artefacts and it has even a room dedicated to an English fantasy artist as well as the more usual medieval stuff.

For me though, the clincher is the Geiger Museum. Hans Ruedi Geiger is the mad Swiss behind the Alien movie design, the creator of the monster and the museum is dedicated to that and is more gruesome creations. It's not particularly for kids and there is a section which is for adults only but it is quite incredible to find such a place in Gruyeres. Right next to it, there is a Geiger Bar where you can have a drink in some extraordinary surroundings...

Accomodation up there is quite pricey but there is a farm half-way up the hill where you can get room with breakfast for 45 chf pp. It's very much "share with the family" and it's a working farm which produces diary products. Their cheese is top drawer and you can have as much as you want at breakfast, which even after a fondue feast the day before, you won't mind doing!
