I just found a nice sim in Second Life: Jura, France
A French-speaking guide showed me around, showing me a wine cellar, a cheese shop, the port and a mock-up of Louis Pasteur's house. There is a Christmas Village there too, complete with ski resort, chair lift and Father Christmas!
Then the guide directed me to a magic chair that took me on a tour of the whole region, with a commentary in French. I could have chosen English too, but I need to brush up my French!
Worth a visit!
