Land during rail hours and you can use the RER Train from CDG to Paris to reach the center without road traffic or a costly transfer. Follow signs for “Paris by train,” take RER B toward the city, and get off at the station that gives your hotel the simplest onward connection.

Trains usually run every 6–15 minutes from roughly 4:50 a.m. to midnight. Allow extra time for the walk from your terminal, ticket purchase, platform access, and any metro transfer after reaching Paris.

Taking RER B From CDG: The Steps That Matter

The RER B trip is straightforward once you reach the correct airport station. The main mistakes are following signs for the TGV instead of the RER, buying a regular city ticket, or getting off at a Paris stop that creates an awkward transfer.

1. Follow the rail signs. Look for “Paris by train,” “RER B,” or the blue RER B symbol after baggage claim.
2. Choose the airport station for your terminal. Terminal 2 uses Aéroport Charles de Gaulle 2 TGV; Terminals 1 and 3 use Aéroport Charles de Gaulle 1, with the free CDGVAL needed from Terminal 1.
3. Buy the airport fare. Select the Paris Region Airports ticket, not the standard Metro-Train-RER ticket.
4. Validate before boarding. Tap the loaded Navigo Easy pass or phone at the gate and keep the same device ready for the exit gates in Paris.
5. Board a Paris-bound RER B. Trains leaving the airport run through Gare du Nord, Châtelet-Les Halles, Saint-Michel–Notre-Dame, Luxembourg, and Denfert-Rochereau.
6. Transfer inside the network. The airport ticket permits metro, RER, and train connections for up to two hours from first validation, provided you do not leave the gated system.

Which CDG RER Station Should You Use?

Charles de Gaulle Airport has two RER B stations, and the correct one depends on the terminal printed on your boarding pass. Terminal 1 passengers should take the free CDGVAL to the Roissypôle stop; Terminal 3 passengers can walk to the same station.

Aéroport Charles de Gaulle 2 TGV sits between the main Terminal 2 halls. Terminals 2C, 2D, 2E, and 2F are generally reachable on foot, while Terminals 2A and 2B require a longer terminal connection. Terminal 2G requires the airport’s N2 shuttle from Terminal 2F.

Do not confuse the services: TGV signs lead to long-distance trains. For central Paris, follow the RER B signs even when both services share the Terminal 2 station complex.

CDG To Paris By RER B: Stops And Connections

Gare du Nord is the fastest central stop, while Châtelet-Les Halles usually gives the widest range of metro connections. Saint-Michel–Notre-Dame, Luxembourg, and Denfert-Rochereau can save time when the hotel is south of the Seine.

Ride times are planning ranges from the Terminal 2 station; stopping patterns, platform waits, and works can change the total. From Terminal 1, add the CDGVAL transfer and station walk.

Tickets, Fares And Transfers In 2026

The 2026 Paris Region Airports ticket costs about $16 (€14) at full price and $8 (€7) at the reduced rate for eligible travelers. The fare covers RER B from CDG plus metro, RER, or train connections made inside the network within two hours.

Île-de-France Mobilités lists the current fare, purchase methods, transfer window, and exclusions on its official Paris Region Airports ticket page. The ticket can be loaded onto a Navigo Easy pass or a compatible iPhone or Android phone through the regional transport app.

• A standard $3 (€2.55) Metro-Train-RER ticket does not cover the airport station.
• A 2026 all-zone Navigo Weekly pass costs about $37 (€32.40) and includes the RER B airport trip; the pass runs Monday through Sunday rather than for any rolling seven-day period.
• The $14 (€12.30) Navigo Day pass excludes airport travel.
• Paris Visite includes airport travel, but a one-day adult pass starts near $35 (€30.60), so it is rarely the cheapest choice for one airport ride.

Currency note: Dollar estimates use €1 = about $1.14, close to the European Central Bank reference rate on July 9, 2026. Card issuers may use a different rate.

Is The RER B Right For Your Arrival?

The RER B is the strongest choice for one or two travelers heading near a central station, provided both can manage their luggage through gates, corridors, stairs, and a possible metro transfer. A taxi becomes more competitive for three or four people, heavy bags, small children, limited mobility, or a hotel far from a useful rail stop.

Use only the signed taxi ranks outside the terminals. Paris Aéroport lists fixed 2026 taxi fares of €56 to the Right Bank and €65 to the Left Bank; drivers soliciting passengers inside the terminal are not the official rank queue.

Where To Stay For A Simple Airport Transfer

Hotels near Gare du Nord, Châtelet-Les Halles, Saint-Michel–Notre-Dame, or Denfert-Rochereau reduce the number of stairs and transfers after a long flight. A property a few blocks from one direct RER B stop can be easier than a more central address requiring two metro changes.

Compare hotel locations against the RER B stations before choosing a room:

Luggage, Personal Security And Service Disruptions

RER B trains have no reserved seats and limited dedicated luggage space, so keep bags beside you without blocking doors. Place phones and wallets away before the doors open at busy central stations, where crowded platforms make distraction theft easier.

Paris Aéroport warns that major RER B works are scheduled during 2026, with some evening and weekend closures. Check live service in the Île-de-France Mobilités or Bonjour RATP app on arrival day, especially after 10 p.m.; replacement buses can add substantial time.

Step-free routes depend on working elevators at both the RER station and the onward metro stop. Travelers who cannot use stairs should confirm current elevator status or arrange an accessible road transfer.

Older pages may still tell travelers to take RoissyBus to Opéra. RoissyBus ended on March 1, 2026, and line 9517 now links Roissypôle with Saint-Denis Pleyel rather than running directly to Opéra.

The Best Route For Each Paris Area

The right CDG rail stop is the one that leaves the shortest practical final leg, not always the first stop inside Paris. Use these pairings as the arrival plan:

• Gare du Nord or Gare de l’Est: leave at Gare du Nord and walk or make the short internal connection.
• Le Marais, the Louvre, or Bastille: leave at Châtelet-Les Halles, then walk or take metro line 1.
• Saint-Germain-des-Prés or Notre-Dame: leave at Saint-Michel–Notre-Dame; some hotels are walkable from the station.
• Latin Quarter or Luxembourg Gardens: stay on RER B to Luxembourg.
• Montparnasse or the southern 14th: leave at Denfert-Rochereau, then use metro line 4 or 6 if needed.
• Heavy luggage, a group of four, or a late landing: use an official taxi rank and confirm whether the address is on the Right or Left Bank.

For most daytime arrivals, RER B wins on price and predictable timing. Compare departures once more if the flight lands late or planned works affect the line:
