The Chateau de Villandry was my favorite with Chmenceau coming in a close second. Both castles had huge moats and you could take a boat ride along the river.
I can't believe I am down to my last 4 days in Paris. If I wasn't going to Italy and then coming back to France, I think I would be spending my last few days in tears! :-) I have to say, Paris is not completely my cup of tea - too much pollution for me - but as soon as you travel a little outside of the city, it is amazing. Also, while I didn't get to see the end of the Tour de France, I definitely heard about it and saw pictures! Even French people who aren't into cycling follow the tour and there is an update on the news every single night of who is in the lead and who is in the yellow jersey. Very exciting!
