Option 2: Train
The RER B line is the usual mode of transport for the majority of people who do not have a car, and there is a reason for this: it is the best one. It is fast, it runs all day and it bypasses all the road traffic which is quite significant on a route which partly follows some rather busy motorways.
Pros & Con
There is no direct train that will get you to Gare de l’Est, however, the solution is as painless as they come. The two stations are just a few hundred metres apart and located in the same neighbourhood, and the walk between them is very simple – mostly flat and easy to follow, even if you’ve never been to Paris before – taking the RER B from CDG to Gare du Nord and then a five to ten-minute walk from Gare du Nord to Gare de l’Est. The good news is that there’s no hassle with traffic, trains run every hour and it’s a short flat stroll to the end of the ride. The disadvantages are the same as with any train ride with suitcases: it can become crowded on the RER B during rush hour, especially on the early evening train when commuters are returning home from their work.
For future reference: a new CDG Express service will start in spring 2027, which will provide a direct 20-minute service between the airport and Gare de l’Est without a transfer at either end. Not yet, but it would be even easier than this one if you are on the road for the future and want to take it.
Train Tickets & Booking
RER B tickets for the train from CDG to Gare du Nord cost an average of €10-14 for an adult, and can be bought from the ticket booth at the CDG terminals before getting on or via Ile-de-France Mobilités’ app in advance. There is no need to reserve a ticket and no second ticket needed for a short walk across to Gare de l’Est, so ticketing is as simple as it gets on this trip.
Usually they ride at a reduced rate or free, according to age, and be sure to check the current rates when you get on the bus—the rates may change from time to time at the machine.
Train Travel Time & Frequency
The RER B trains from CDG are approximately hourly and the wait between them is not a problem as long as it’s around 10-15 minutes between trains until just before midnight. The journey from outside to Gare du Nord is approximately 30-35 minutes, and the walk to Gare de l’Est is a mere hop, skipping and a jump, so as a result it is likely to be the quickest public transport option on this route.
Option 3: Bus
This is a place where a straight bus runs from A to B (as opposed to some of the more complicated cross-Paris journeys, where you have to switch buses after you get off the first one or travel by two different ones), no transfers, and no having to piece together two different bus lines. Not as fast as the train but easy and inexpensive.
Bus Routes & Stops
The bus departs directly from CDG to Gare de l’Est with a stop at Gare du Nord. It leaves from the bus station above the RER Terminal 1/3 station and also stops at Terminal 2, so if you get off at any of the stations there’s always a stop close by. Well done for a proper single-seat trip from the airport to your destination, which isn’t true of a number of the routes in this series.
Bus Fares & Schedules
This is by far the lowest cost option: tickets are purchased from the driver or from a vending machine located near the stop, and cost about €2.10. The 350 runs take place 15 to 30 minutes each, depending on the time of day, from approximately 6:05am until 10:30pm. The train journey takes about 30 minutes, but the bus one takes 60-90 minutes — it’s much longer, although it’s not that different from the train in terms of distance. The N140 and N143 Noctilien night buses are available for last minute arrivals outside those times and run directly to Gare de l’Est, a convenient alternative if RER service ends at night.
Comparison Table: Cost, Time, Convenience
| Mode | Travel Time | Cost | Convenience | Best For |
| Private Transfer / Taxi | 30 – 35 minutes (up to 50+ in traffic) | €50 – €65 (flat rate ~€53 by metered taxi) | Highest — door-to-door, no transfers | Families, tired flyers, heavy luggage |
| RER B + Short Walk | 35 – 45 minutes | €10 – €14 | Moderate — no change, short walk at the end | Solo travellers, budget-conscious visitors |
| Bus (RATP 350) | 60 – 90 minutes | ~€2.10 | Moderate — direct route, but slower and busier | Budget travellers not in a hurry |
These three match up and it is pretty clear this is a track where each option is going to be fairly effective; it is more a question of priorities as opposed to a weak link. The private transfer or a taxi, which is priced by the flat rate, takes about half an hour and is very convenient, if speed and comfort are the top priority or if you have to catch an onward train on time.
The RER B is indeed the most intelligent option if you are able to take your own bag a short distance, quicker than the bus, cheaper than the taxi and running so often that you are never left long waiting in time. The bus is a viable option primarily for budget-conscious travelers who do not need to travel quickly, as the ticket cost is €2.10 and although the journey takes twice the amount of time as the train, the price is still very competitive. This is not an error question, just a time/cost tradeoff versus how much you want to think about after a long flight.
Conclusion
Charles de Gaulle to Gare de l’est is as simple as getting from Paris airport as you can get it, regardless of which one you use you will have little hassle. For the fastest and most comfortable ride (and a slightly higher price) a private transfer or flat-rate taxi will do the job in about 30 minutes. If you’re okay carrying your own bags for a short stroll, the RER B isn’t to be overlooked in terms of speed and cost effectiveness. But if it’s the money that’s important, not the time, then there is the direct 350 bus, which will take you there, though longer.
