It’s always difficult to make a selection of the most beautiful places in Paris. I think the perfect itinerary for three days in Paris is this (bring comfortable shoes because you will have to walking a lot!):
Spend the morning of the first day at the Louvre, obligatory stop in Paris also for those who are not a lover of museums. Prepare yourself before with a mental itinerary of the art works that you prefer to see because the Louvre is so big that it would take several days to visit it entirely! Open every day, except Tuesdays, here’s times, map and all useful information to plan your visit: Information about Louvre If there is a long queue at the entrance, do not be intimidated, and use a secondary entrance less known of the Louvre! In the link you will find the addresses of the other entrances, I recommend the entry from the Galerie du Carrousel so you will pass also in front of the point where the two pyramids meet (those who have read The Da Vinci Code will immediately understand what I mean!).
For the afternoon I suggest a walk on the Champs-Élysées. If there is good weather, and you want to walk, you can reach them directly from the Louvre passing through the Tuileries garden to the Ferris wheel in the Place de la Concorde, starting point of the Champs-Elysees that you can cross to the Arc de Triomphe. If you are tired of walking after the Louvre instead the Arc can be reached directly by underground getting off at Charles de Gaulle – Étoile.
After sunset I recommend you get to the Tour Montparnasse, going up on the 59th floor you will have a view of Paris illuminated. I consider this the most romantic place in Paris! If you want you can also book a dinner in the tower restaurant and dine with a view of Paris.
The tour costs 14 € for adults, 11 for children aged 16 to 20 years and for students; anyway on the website you will find all prices and times for both visits and dinners: Tour Montparnasse
For the morning I recommend you go to Montmartre to see the Sacre Coeur Basilica and from there walk to the Moulin Rouge (it’s not recommend to go in the evening in the Pigalle area where the Moulin Rouge is!).
From there you can reach the Paris Opera (also called Palais Garnier), I suggest you enter to visit it because it’s really beautiful! The circular ceiling in the picture was painted by Marc Chagall.
For shopaholics, near the Opéra you find the Galeries Lafayette department store. Little tip: from the top floor of the department stores you can find a beautiful view of the city.
You can spend the afternoon at the Eiffel Tower, I recommend to get off at Trocadéro station, around the corner you will find the tower in front of you and you can go down by steps and walk right under the Tour.
From there, if you are interested in, some boats leave often making a tour on the Seine showing the main monuments of Paris; you can also book a dinner on the boat. The most famous company is Bateaux Mouches.
I recommend you to visit the Notre-Dame Cathedral in the morning, don’t be discouraged by the queue at the entrance because it is very fast! You can visit the interior and, in case you want (and you have the resistance!) to make 378 steps of a spiral staircase, climb the towers to see Paris from the top and the famous gargoyles.
If you are interested in art then I recommend the Musée d’Orsay, famous for its Impressionist masterpieces contained inside and for the fact that it was built in an old train station. But if you prefer contemporary art, you can not miss the Centre Pompidou.
