Once you have bought your ticket for the RER Line B trains from Paris-Charles de Gaulle Airport to central Paris, look for the monitor that shows the trains:

Reading from left to right, first comes "RER" then "B" then the four-letter code identifying the train. (Here's how to interpret the codes).

Then comes destination and station information, and finally the track number (11 or 12).

It's good to remember that you can board any RER train at CDG Airport's Aérogare 2 and it will take you to central Paris. But you'll get there faster and more comfortably, with less chance of crowding, on a train that makes fewer stops.

Having chosen your train, look for the doors marked:


(See the photo on the right—>).

(Don't go to the TGV tracks or you may end up in some other part of France, or even in Brussels!)

Insert your ticket in the turnstile, descend by escalator, stairs or elevator to the tracks, check the track number (Voie) and the four-letter code for your train, check the clock for the departure time, board your train and ride.

Many RER train cars have baggage compartments for bicycles at one end. If you have lots of luggage, you can put it in the bicycle compartment and ride in seats nearby.

Look for this logo to find the bicycle compartment —>

RER Line B Central Paris Stations

Gare du Nord

Called PARIS NORD on the signs in the RER station at that stop, this is a a major SNCF intercity train station. More...

Châtelet Les Halles

On the Right Bank of the River Seine in the very center of Paris near the Louvre, Hôtel de Ville and Le Marais, this station is the heart of the Paris Métro system. It's the largest Metro station in Europe—vast and confusing.

St-Michel Notre Dame

The very heart of Paris on the Left Bank near Île de la Cité, Notre Dame, the Latin Quarter and the Sorbonne.


Near the Jardin du Luxembourg, Église de St-Sulpice and Panthéon in the Latin Quarter.

Denfert Rochereau

This intersection of major boulevards in the southern part of Paris is an important transport nexus, with connections to Paris-Orly Airport.

Which Station to Choose

If your hotel or apartment is in the center of Paris, you'll probably want Châtelet Les Halles or St-Michel Notre Dame, but from any of these stations you can transfer to the Métro or a taxi (minimum fare 7€) to reach your final destination.

Remember: All RER trains from CDG Airport go to central Paris, and hold on to your ticket. You'll need it to exit the train station in central Paris.
