This list is according to Imei:

1. Go to the viewing gallery of the Eiffel Tower (known as the Tour Eiffel) at 274 meters. On a windy day, you might even feel like you’re swaying. Make sure to give yourself up to four hours, including times in the queues from bottom to top.
2. Say hello to the Mona Lisa at the Musee du Louvre. It’s likely there will be a crowd of tourists doing the same thing, so be patient.
3. Visit Jim Morrison’s grave in Pere LaChaise. People leave him bottles of wine and beer, flowers, poems, and other unusual gifts.
4. Browse the stores of des Champs-Elyses if you enjoy high-end boutiques and the best shopping. If you work up a hunger, buy some affordable luxury in the form of the patisserie Laduree, and purchase four, eight, or twelve of their famous macaroons. It’s like a decadent Oreo, only much better.
5. Don’t see anything you wish to buy on the Champs-Elyses? No worries. Just keep walking towards that giant gate you see, and take pictures as you approach the Arc de Triomphe. Morning is the best time to catch the gold tone and the intricate designs on the stone.
6. Take a walk around Montmarte and walk the steps to the Sacre-Coeur (Sacred Heart), one of the more famous cathedrals in Paris. Bring your camera at sunset for one of the best panoramic views of the city. From here, you’ll understand why Parisians grow teary over their beloved Eiffel Tower. Enjoy the artsy area, purchase your own hand-painted scenes of Paris, and gawk
7. Take a walk along the left bank (Rive Gauche) of the Seine, to view Notre Dame Cathedral and enjoy the bookstalls of the Latin Quarter. Then walk across the bridge and take a tour. There are free organ recitals every Sunday afternoon on France’s largest organ. Chillingly loud.
8. Literary buff? Then you must go to Boulevard St-Germain in the Latin Quarter. Take a coffee at Les Deux Magots or Cafe Flore, and debate like the intellectuals. Quote Camus, and whine about absinthe. Just don’t order a Coke, or you’re in for a shock.
9. Take your children to Jardin du Luxembourg, and discover for yourself how Parisians manage to raise such adorable and well-mannered children. There is still a charming merry-go-round completed around the 19th century, replete with a game for children involving hand-held sticks and rings the children attempt to catch whilst they get dizzy enough to lose their lunches.
10. Got an extra day to spare? Visit Versailles, which is a day trip outside of Paris via the RER line C. You’ll want to plan this trip carefully if you only have a day, and begin your guided tour early of the palace. Bring your walking shoes, as there are beautiful gardens to explore. If you want to find some cheaper eats, save your appetite and walk into town.

What else is there to do in Paris? Ya know, off-the-beaten path things?
