would it be crazy to visit the Louvre on july 14th (Bastille day) or might the crowds be paradoxically thin due to all the street celebrations ?
William, Unlike the Americans who picnic on the 4th of July, the French do their celebrating in the evening. On the morning of the 14th a lot of people are sleeping in because the real celebrations, street dances, are on the 13th, starting late and going into the wee hours. Of course there is the military parade down the Champs Elysee on the morning of the 14th and the official receptions given by the government, but those are for the bigwigs. Would it be crazy? If you try it, let us know how your 13th and 14th went.
Check their website and make sure they're open on the 14th, I know they were closed 1 May, which is a big holiday in Europe.
