It’s hard not to go in the summer if you have kids and this is the time they’re off, but try to schedule your trip during Spring Break when the weather is great, prices are cheaper, and there are fewer tourists.
If you don’t mind the cold and snow, then by all means, look into winter trips to Paris. Your flight will be cheapest off season, so winter can help you save money. Just realize you’ll be walking a lot in the chill and pack accordingly.Our trip had an extra consideration, as it was the worst winter in 50 years. Snow caused all sorts of traffic delays, so keep that in mind when planning.
The best time to visit Paris is a season you enjoy traveling in. It might cost extra or be more crowded, but you’ll be happiest if the weather meets your expectations.
