Reaching Paris


Paris is served by multiple train stations.

French contestants willing to arrive and depart by train should consider the Massy TGV train station as a convenient alternative to central stations. Some trains (especially low-cost Ouigo trains, but also some standard TGV trains) go to the Massy-Palaiseau TGV station but not to central Paris.

Otherwise, trains from Switzerland (Lausanne, Geneva, Zürich), trains from Italy (Milan, Turin), and most trains from Spain (e.g., Barcelona) arrive at Gare de Lyon.

Train trips from SWERC member countries which arrive in other stations than Gare du Lyon include trips from Irún (via Hendaye) which arrive at Gare Montparnasse.

Other less convenient train stations in the greater Paris area, served by some low-cost trains (e.g., Ouigo trains), include the train station of Marne-la-Vallée TGV near Disneyland, and Aéroport Charles-de-Gaulle TGV. Marne-la-Vallée is served by suburban trains (RER line A, allowing you to reach RER line B), and Aéroport Charles-de-Gaulle is served by RER line B just like the CDG airport (see below).


Paris is served by two airports: Orly (ORY) and Charles-de-Gaulle (CDG). Some low-cost carriers operate flights to Paris-Beauvais (BVA), but this is significantly further away. Note that the recommended hotel and the contest venue are significantly closer to ORY than to CDG, so we recommend flying to ORY if possible.

Given the price of public transportation to and from the ORY and CDG airports, it may be cheaper and more convenient for groups to take a taxi or arrange a private transfer service (e.g. AlloCab, Eurecab, Kapten, LeCab, Marcel, etc). Otherwise, we will list public transportation here later.


A cheap option to reach Paris is to travel with long-distance buses. There are multiple search engines to look for trips, e.g., Goeuro, Comparabus, CheckMyBus, etc.

Getting around in Paris

There are various ways to plan for trips in Paris, including the Citymapper smartphone app and website. It works well for the areas around the hotel and contest venue, and features public transportation in addition to other transportation means.

Reaching the contest venue

Details about transportation will be posted here later.

We do not recommend travelling to the contest venue on your own, unless you are familiar with the area. The venue can be reached by taking an RER B train to one of the following stops (be careful that trains may not travel to, or stop at, these stations):

  • Massy-Palaiseau, and then taking bus line 91.06 or 91.10 to stop “Place Marguerite Perey”. These buses require a specific ticket (in addition to the RER ticket). Note that the buses can be very infrequent during the weekend (up to one bus per hour) and/or crowded. Bus line 91.10 also connects to the Orly airport (but there is only one bus per hour, so it cannot be relied on).
  • Lozère or le Guichet, and then walking up to the contest venue (25 minutes, steep uphill walk in the woods).

You can also arrange taxis or transfers on your own, but it is strongly recommended to book them in advance. Ridesharing apps are also an option.
