Arriving by plane

Be prepared for long lines at Charles de Gaulle to buy tickets. Individual tickets and carnets can be bought at vending machines but most if not all machines only accept credit cards with chips and a PIN. There are different types of machines: you want Transilien (blue, grey colors), not the yellow SNCF machines. You can also get tickets at the ticket counter.

Be wary of pickpockets on the RER B train from Charles de Gaulle, and if possible take the train that goes straight from the airport to Paris. Pickpockets especially love inattentive passengers with loosely attended backpacks.

Door to door shuttles exist, but not very common. Taxis are available at all airports. Taxi fare from Charles de Gaulle airport is approximately 50 € during the day (more expensive at night or on weekends).
More information about getting to and from the airport can be found at

Our suggestion: When you arrive at the airport buy a return ticket to Paris, and keep the second coupon for your trip back. For your trips in Paris during your stay buy (at any metro station) a "carnet" which consists of 10 tickets . It is much cheaper than buying the tickets individually. They can be used for subway or buses inside Paris.

If you plan on using public transportation frequently during your stay, you should consider buying a weekly pass. These are valid Monday through Sunday, and require buying a non-refundable Navigo decouverte (5 €) card plus a weekly fee of 15-37 € depending on the number of travel zones you need. Paris is zone 1. Zones 1-5 will get you to Charles de Gaulle airport. Orly is in zone 5 but access to OrlyVal is not included in the weekly pass; OrlyBus is. Versailles is in zone 4. Auvers sur Oise is in zone 5. Fonainebleau is on zone 6.

Arriving by train

The French train system is very efficient and relatively inexpensive. Please see the SNCF web site for schedules, prices, and reservations. The conference venue is easily accessible by metro and RER from the train stations (Gare du Nord, Gare de l'Est, Gare de Lyon, Gare Montparnasse etc.).
