What time is a best time to visit Paris?
(Summer, autumn...)

I think there´s no best time. Paris is always touristic, but I guess during summer it´s much more crowded. You can have a lot of waiting to enter the museums or get on the Eiffel Tower, but the good thing in summer is they set the man made beach all along the Seine.

Thank you very much, Mltm.

Spring is traditionally the best time to visit Paris. You can relax as you walk around the beautiful city, take a boat trip down the Seine, visit the Louvre and forget all lists

Have you remembered this song :
"I love Paris in spring time"
