Paris has an established and affordable metro system that is fast and convenient. The travel cost for a one-way journey is about €1.90. Taxis and Uber are also readily available options for transportation, but they can be quite expensive.
If you have an extra day, consider visiting the Palace of Versailles or Disneyland Paris. Alternatively, if you have less time, consider a hop-on-hop-off bus tour to see the top sights in a shorter time frame. To save money, consider visiting the Louvre and Eiffel Tower on Fridays when they offer free entry after 6 pm.
Paris has two main airports, Charles de Gaulle Airport (CDG) and Orly Airport (ORY). Charles de Gaulle is located about 23 km from the city center and is the largest airport in France. Orly Airport is located around 16 km south of the city center and is smaller but still serves many international airlines.
