Airport transportation
The simplest and fastest way from Paris’ Charles de Gaulle Airport (CDG) to central Paris is the City train RER line B (about 50 min, one train every ~15 min). Once at the airport train station’s large atrium, follow escalators down to Paris city trains (RER B) and Grandes Lignes trains (TGV intercity trains) to buy Paris train tickets. Your RER train ticket will cost 10.30 € and is also good for connections onto the Paris Metro and other RER train lines once you’ve arrived inside Paris’ city limits (on line B : all stations between Gare du Nord and Cité Universitaire). Useful websites give you directions and recommendations, such as this one.
RER and metro ticket vending machines
At CDG Terminal 2 train station are boxy white & blue ticket vending machines labeled as Tickets Navigo Paris et Ile de France – train, RER, bus, tramway, metro. Use these machines to buy your RER B ticket to destination. At peak hours, passenger lines forming in front of these machines may be discouraging. The interactive touch-screen menu comes in English. Credit cards with a smart chip + PIN will most likely work.
