Arrival by airplane

If you are travelling to Paris by plane, you will arrive at Charles de Gaulle Airport or Orly Airport.

To get from Charles de Gaulle Airport, to the city center:

By train One of the quickest and cheapest ways to travel into the centre of Paris is by the RER B (blue) train line that has station stops at both Terminal 2 and Terminal 3 of the airport. (Note Terminal 2 has seven sub-terminals, but all sub-terminals can be accessed by foot or via the free N1, N2 and N3 shuttle buses). If you arrive in Terminal 1, take the free shuttle train to Terminal 3, which is the easiest station to catch the RER B from. You can buy train tickets from one of the blue ticket machines (not the yellow machines, which sell TGV tickets only) or from a train station employee in a booth. Tickets cost 10.3€ one-way and the journey takes up to 50 minutes. Make sure you take the RER B line heading in the direction of Robinson, Antony or St-Rémy-lès-Chevreuse and the train will stop in central Paris stations such as Gare du Nord. Trains run from Charles de Gaulle Airport to Paris between 04:46 and 23:56 Monday to Sunday.
 By busThe Roissy bus is one of the most popular buses to take from Charles de Gaulle Airport to the centre of Paris. The bus leaves from all three terminals and runs from 06:00 to 23:00 every day. They run every 15 minutes until 20:45, and then every 20 minutes until 23:00. The journey takes up to an hour, terminating in the Opéra area. If you’re arriving at night, night buses N140 and N143 run seven days a week and depart from all three terminals. Bus N140 runs hourly to Paris between 01:00 and 03:00, while the N143 runs from midnight until 04:30 at half-hourly intervals. Both buses terminate at Gare de l’Est.
By taxiThere are taxi ranks at all three terminals and you can spot legitimate taxis by the yellow lights on the roof. A fare to Paris city centre costs approximately 60.00€, rising by another 10.00€ at peak or overnight times (typically between 17:00 and 07:00). The journey can take more than an hour at busy times.

 To get from Orly Airport, to the city center:

By train RER B: This airport’s closest RER station is Antony (about 5 miles away from the airport) and is accessible thanks to a shuttle called Orlyval that departs from the South and West terminals. It will cost you 11.30€ for a one-way ticket (this price includes the Orlyval ticket as well as the RER one) and you will be able to buy it at the ticket counter before your departure. The Orlyval runs every three minutes between 6am and 11pm and the ride lasts for 10 minutes. When you get to Antony station, you will have to take the blue line in the direction of Mitry-Claye or aéroport Charles de Gaulle. The RER takes about 30 minutes to reach downtown Paris (Gare du Nord stop) RER C: Another RER line links the center of Paris to the airport Orly and it is the line C that will cost you less but will take longer than the RER B/Orlyval option. To get there, you will have to take a shuttle to the RER station Pont de Rungis-Aéroport Orly, it runs around every 20 minutes between 5am and 11pm and the ride is only 10 minutes. This journey will only cost you 2.50€ per person. Once you are at the station Pont de Rungis, you will only have to take the yellow line, the one for the RER C, with the direction Pontoise or Montigny Beauchamp. The ride is about 40 minutes long and costs 3.90€ for a one-way ticket. Destinations at the center of Paris: Paris Austerlitz, les Invalides.
 By busORLYBUS: Just like the airport Charles de Gaulle, Orly has its own bus that will get you to the center of Paris. The Orlybus departs from both terminals every 10 to 20 minutes between 6am and 12.30am. It will get you to Paris Denfert-Rochereau in the southern part of the center of Paris and will cost you 11.2€ for a one-way ticket which you can buy directly on the bus. Destinations at the center of Paris: Paris Denfert-Rochereau
Bus 183: Bus 183 is the cheapest solution. It departs from the South terminal every half-hour and takes about 90 minutes to get to its last stop: Porte de Choisy. A one-way ticket will cost you 2.5€ and you can buy it on the bus. Destinations at the center of Paris: Porte de Choisy
Bus 285: Also leaves from the South terminal and goes all the way to the subway station Villejuif-Louis Aragon in 15 minutes. This will also cost you 2.5€ for a one-way ticket and there is a bus every 10/20 minutes from Monday to Saturday and every 30 minutes on Sundays. When it comes to times, both buses run between 5am and 1am from Monday to Sunday. Destinations at the center of Paris: Villejuif-Louis Aragon
AUTOCAR AIR FRANCE LINE 1: Air France provides you with a bus line that links the airport Orly to the center of Paris. Line 1 departs from both terminals and stops at the Arc de Triomphe as well as stopping by the Gare Montparnasse. The bus runs from 6am to 11.40pm and departs every half-hour. The ride will take about 45 minutes with price of 17€. Destinations at the center of Paris: Gare Montparnasse, Eiffel Tower, Trocadéro, Champs-Elysées.
LINE N131 (Night Bus): This night bus departs from the South terminal of Orly airport. To reach this terminal, you have a free shuttle at your disposal called “Navette Parking” that leads to the terminals Orly Sud and Orly Ouest to get you to your bus safely. This shuttle runs from 3.30am to 12.30am and departs every 9 to 19 minutes. The night bus ticket will cost 6€ and you can buy it directly on the bus, at the airport, or even in any RER/subway station. Destinations at the center of Paris: Gare de Lyon
LINE N144 (Night bus): This night bus departs from the South terminal of Orly airport. To reach this terminal, you have a free shuttle at your disposal called “Navette Parking” that leads to the terminals Orly Sud and Orly Ouest to get you to your bus safely. This shuttle runs from 3.30am to 12.30am and departs every 9 to 19 minutes. The night bus ticket will cost 6€ and you can buy it directly on the bus, at the airport, or even in any RER/subway station. Destinations at the center of Paris: Châtelet, Gare de Lyon, Gare de l’Est.
By taxiYou will find taxi stations at the two terminals and the ride will cost you 30€ for the right bank and 35€ for the left bank (inclusive price). The ride will last about forty minutes depending on traffic and where you want to go.

Arrival by train

All of Paris’s train stations are connected to the public transport system. There are seven major train stations in Paris:

  • Gare du Nord: The busiest railway station in Europe and the hub for trains arriving and departing Paris on the Eurostar. With Thalys the Gare du Nord also serves Belgium, the Netherlands, and Germany. Along with the local and national train lines this station is always a bustling beehive of activity with trains running to Northern France and the Northern suburbs of Paris.
  • Gare de l’Est: Located a short ten minute walk from Gare du Nord (you can also take the bus or metro). Connects to Gare Magenta. Trains go to eastern France and Germany plus the eastern suburbs of Paris.
  • Gare d’Austerlitz: Trains go to central France, Toulouse and the Pyrenees. Elipsos also runs trains to Barcelona.
  • Gare de Bercy: Trains to Italy and Burgundy.
  • Gare de Lyon: Trains to south-east France, Languedoc-Roussillon, Switzerland and Italy. Trains also run to the south-eastern suburbs of Paris.
  • Gare Montparnasse: Trains to western and south-western France and Madrid. Trains also run to the western suburbs of Paris.
  • Gare Saint-Lazare: Trains to Normandy and to the west and south-western suburbs of Paris.
