Trains from CDG to central Paris?

It's the same train that it has been for decades -- the RER B. It costs €10.30 (as of August 2018) for a one-way ticket to anywhere in central Paris, including a transfer to the Paris Métro or other RER lines if necessary to reach your destination.

I generally also strongly prefer the train between CDG and Paris, but depending on where your hotel may be it it may be preferable to take Le Bus Direct to your destination which can avoid making transfers.

I have taken the RER B 8 times over 16 years most recently December 2017with out problem.

The RER is easy to ride; just be aware of pickpockets when you're purchasing your RER ticket, etc. Enjoy your time in beautiful Paris!

We always take the RER to the airport into the city. There are lots of instructions and youtube videos to walk you through it if you want more information. It was helpful for me the first time as I was coming off a 9 1/2 hour flight. It's good to google map directions to your first point (capture the instructions as a photo on your phone) when you come off the RER in case you are growing weary. I know it's old school but it has saved us a few times. You will be fine. We are in our 50/60's and travel with a carry on and back pack.

This one is a no brainer in that all the RER trains are going to Paris. You can't make a mistake. Buy the 10.30 ticket at a machine and there you go. Note that a backpack is a pickpocket's dream so be sure your valuables are either in a money belt under your clothes or otherwise well secured -- not in pockets or in outer pockets of a backpack or in the top --

The number of people in your party is what will determine if the RER is really cheaper than a taxi. If you're two people, train is cheaper. With three, the difference in price becomes negligible for the convenience gained, and with four, it pretty much disappears.

This rapid transit planner will help you throughout your stay in Paris. Try to catch an RER 2 that is express to Gare du Nord. The ticket you bought at the airport is good to your destination; you will use it to exit the RER B at Gare du Nord (or wherever) and then enter the Metro line to finish the trip. Always keep Metro/RER tickets until you have left your destination station; on the Metro there are occasional spot checks with stiff fines if you have not kept your ticket.

Technically, I think the trains have had their names changed from RER. However, all the signs still say RER and everybody still calls them RER. I'm not sure I can even remember what the new name is........

What day of the week will you be arriving? If it is early in the week, you may want to consider buying a Navigo Decouverte card at the airport train station. This will give you unlimited RER, metro and buses for up to a week. Check out the website for more info.

You board the RER train at its first stop which is the airport. This means you choose where you sit and how you sit with your luggage. I think that you will be just fine and that you need not get too worried about pickpockets if you just use common sense.

I always give myself the option of taking a taxi if I arrive at a location and discover that I am too tired to think straight. I think you could plan on taking the train and have a very successful trip. If you are tired or feeling poorly after your flight, just treat yourself to a taxi. You are worth it!

In Paris two weeks ago. We elected to use "Super Shuttle" and be dropped in front of our hotel. We stayed outside central downtown Paris. Our hotel helped reserve the shuttle. Highly recommend going to the train information office in the CDG airport. They helped book our train tickets from Paris to Strasbourg. Very helpful.

Thanks all for the advice and suggestions. We’re going to stick with the train. There’s one transfer to the hotel we may be staying at. But we’ll see after we arrive how we feel etc. I’m just so looking forward to this because Paris can not come soon enough!

If your going to be using public transportation in Paris, and your their for a week, purchase the Navigo card- it basically pays for itself because a one way RER B ticket cost $10.30 euros for adults, and presuming your going back to the airport to leave, the Navigo Decouverte costs around $24 euros ( As of May 2018) so using the metro all throughout Paris and the buses were basically free- the pass is weekly and depending when you arrive may not be cost advantage- but def research. It worked for us- make a photo copy of your drivers license, they will cut the picture out and the pass is good for 10 years (to reload)
Happy Travels💫✨

Yes! Thank you also for this reply! In fact I changed our dates for our week in Paris to take advantage of this pass! We plan on using the RER and metro to go all over Paris. I took our first step and booked our hotel for Paris yesterday!! I’m so excited!!
