Where is the best place in Paris that I should visit?

Paris is really a wonderful city, and whatever you pick up from the travel guides, you will not regret it. Depends on how much time you will spend there and what are your interests, simply go by the recommendations of basically any travel books or websites about Paris. They will tell you the Notre Dame, the Eiffel Tower, the Louvre, the Champs Elysee, the Monmartre with the Sacre Coeur and a couple of other things and you should really see them. These are all #1s, if it was possible, I would go and see ALL of them at the first place. :-) So, as you will anyway see them, just start with the most practical one: if it's sunshine, go up to the Eiffel or stroll along the Champs Elysee, if it rains, go inside a church, etc. Or start with the one that fits best by the journey plan according to the map.

Ohhh lá lá.. Paris is a big and very beautiful city, but you can visit the Arc de La defense, L tour montparnasse, le palais de versailes, and you must visit the triomphe arch and the Eiffel tower. Good vacances...

you must start with effiel tower , and take a photo there , very nice place
