Paris is a very walkable city, and many of the major attractions are located within walking distance of each other. However, if you need to travel further, the city has a reliable and efficient metro system. A single ticket costs 1.90 euros and is valid for 90 minutes on any metro line or bus. If you plan to do a lot of sightseeing, it may be worth purchasing a day pass for 14.90 euros.
If you have more time, consider visiting other popular attractions such as the Louvre Museum or the Luxembourg Gardens. For those with less time, consider cutting one of the above activities, or visiting the Eiffel Tower in the afternoon to see it lit up at night.
Paris is served by two main airports: Charles de Gaulle Airport (CDG) and Orly Airport (ORY). CDG is located 14 miles northeast of the city center, while ORY is located 10 miles south. Both airports offer a variety of transportation options to reach the city center. A taxi from CDG to the city center costs approximately 50-55 euros and takes around 45 minutes, while a taxi from ORY costs approximately 30-35 euros and takes around 30 minutes.
