Right seasons to enjoy vacation in France?

All seasons can be nice in France but I prefer the summertime because of the sunny weather...

forget paris... go to the Frenc Riviera at mediterranean sea in the summer... just great

It depends on where in france and what exactly you are looking for. for example Paris is great in spring. winters are a bit gloomy and fall is usually rainy. i wouldnt suggest summer, because if you want to get the authentic feel of paris most parisians are out of town in the summer and the city is packed with tourists. but if you want to go to the south of france like montpellier or marseille or canne then summer for sure. so you can get to experience these places to the max and use the opportunity that you are there and enjoy the mediteranean. have fun!!

Which one? Skiing in the french alps,sight-seeing like the famous Loire Valley with it's castles,sunbathing at the Cote d'Azur... Short advice: avoid August when the french are on holidays (except Paris: apart from Tourist almost no-one).
