This is a vague question! Paris is, in itself, a wonderful city and is great for just walking round the different areas and seeing so much.
Are you interested in arts? theatre? restaurants?
My favourites are the Rodin Sculpture Museum, the Picasso Museum and the Musee D'Orsay. I loved walking around Les Jardins de Luxemborg and also the Sacre Coeur and Montmatre. Notre Dame was wonderful as was the area it is in.
Does this help? If you are a little more specific you will get many more replies. over 7 years ago
Start by the Champs Elysees of course, then you should go to saint germain des pres for a coffee and flaner there, window shopping for the nice little french things, rue bonaparte, cafe flore, where you can really spot international celebrity, then go some place high like the tour eiffel, then go some place chic like avenue montaigne. You can have lunch at l'avenue (expensive) and then go to the opera by night, palais garnier. Or you can see sunset and artists in montmartre.
For top museums go to the louvre, orsay, picasso, rodin.
For top shopping, the opera grand magasins is a must, even you dont buy anything, also the luxury fashion outlet (far), the marais for men cheap nice things, and many other places
For food, the cartier latin is a must, amorino ice cream, a nice cafe on the Champs Elysees, and yes la duree (expensive), and many many others of course
For flaner, just walk around l'ile saint louis with art shops and a relaxing water and notre dame scene, and the berthillion ice cream at the far end of the main street
Wow... This is a beautiful city for everyone over 7 years ago
Eiffel Tower, Paris Moulin Rouge Show and Seine River Cruise
Choose between dinner in Paris at the Eiffel tower or onboard a Seine River cruise
Spectacular Moulin Rouge cabaret show
Complimentary glass of champagne at the Moulin Rouge
These are my favorite
And you can still go walking around your residence(hotel)
And find out other places you can go to
