The OFFICIAL site for tourism in France is www.franceguide.com The site is in English and French and has general information on visiting France, as well as about each region, special offers and good tips. You'll find as well brochures to download (more than 150) and practical information.

Almost every city also has an "office de tourisme".  If you use a web search, just type in the city you want to go to, and "office of tourism".  If they have a page in English, it will probably come up as one of the top choices.
