Hi,
You could also check out the
Fête du Vacherin de Mont D'Or which is held in the village of
Les Charbonnières on 22 September 2007. You'd probably need a car to get to it though.
We went last year and really enjoyed it. There is the descent of the cows which is really noisy and lots of other things going on as it is primarily a cheese festival. We drank and ate well whilst watching the cows, whip crackers, flag throwers, alp horn groups, bell ringers. There were lots of stalls with local producers and tradesmen showing off their skills and wares.
I found some pictures of last year's event on the website of a local hotel
