My husband and I are going to be spending 3-4 weeks in Switzerland this fall. I've considered taking a day trip (and/or spending a night) in France if there is a town that would really be worth seeing. We'll be concentrating our time in the southwestern portion of Switzerland. Is there a town that would give us a sense of experiencing something special about France, as well as being located within an hour or two of the Swiss border? I am not necessarily looking for a touristy location, just a nice place that might give us something different than we could find in the French area of Switzerland.
