Travelers seeking cut-rate flights to France should consider a winter trip. From November through February, airfares to the country are at their cheapest. Those planning a multi-destination itinerary within France should consider rail passes, which offer transportation to several destinations for one flat price within a specified time period. Accommodations in the French countryside can be quite affordable -- and rather fantastic (think chateaux and charming cottages). But the city-bound French tourist should expect steep prices for the choicest accommodations in places like Paris or Marseilles, especially during warmer months.
It's said that Paris has no low season, as the city draws an impressive number of visitors year-round and winter temperatures in the city are rarely unbearable. If you're traveling to Paris, no matter what the season, it's a good idea to book your accommodations well in advance. Summers in Paris are packed with tourists, and it's best to avoid the warmest season of the year if you're crowd-averse. Beyond the City of Lights, different regions in France, which has a temperate climate, have varying weather conditions. The Mediterranean Coast of France is warmer and dryer than, say, the Northwest corner of the country. Research the local weather in the region you're planning to visit before you book your trip.
