Get Cultural in Paris, France
If you don't mind a few afternoon showers, March can be a lovely time to visit Paris. In the heart of the shoulder season, you'll often find discounts on hotel rooms, and lines for popular attractions will be much shorter than in summer, so you can ponder the Mona Lisa in peace. If you visit early in the month, be sure to squeeze in some ice skating at the Hôtel de Ville.
