1. Paris
In 2016, Paris ranked #3 in the top 10 of the most visited cities in the world. The City of Lights is most famous for its amazing Haussmann architecture, for the chic and romantic atmosphere, and for its countless museums. You can easily spend an entire month visiting Paris without being bored. Even for a Parisian, there are always new things to do and places to discover. It took me 4 full days just to visit all of The Louvre.
