Please help me navigate CDG-Paris-Metro transportation options

To know what pass is best, it would help to know the day that you will be arriving and how long you will stay in Paris. There is the Navigo weekly pass that will cover all transit options for a week. It's good for a week running from Monday to Sunday. It could be depending on your arrival day and if you plan to take mass transit to Versailles or Disney or Yerres (and how often you plan to travel between Paris and Yerres) that this pass is best for you. But it could be that you should just buy tickets for the trip between CDG and Paris and a Navigo Easy pass for the rest of your travel within Paris.

Do you really plan to bring 7 people on mass transit from CDG to your accommodations? Will you all be jet lagged? Will you be able to be pick pocket proof? Are you all mass transit savvy? How much luggage do you have? Will you have to connect to the metro to get to your accommodations? Depending on your answers, I think it might be worth the money to budget for a taxi or two to get you to your accommodation in Paris upon arrival. The only time that I was almost pickpocketed in Paris was when I was traveling with young children and focused on helping them on the train.

With 7 people you need a cab -- some hold 7 although not much room for luggage with that many -- you would have some luggage in laps. Public transport would cost roughly 90 euro to Paris. A cab if you could all ride in one (7 is the upper limit) woudl cost about 78 to the left bank (65 base fare plus 4.50 for each person over 4 persons -- I think that is the newest prices for that ). to the right bank would cost about 72).

Public transport from CDG to anywhere in Paris is about 13 Euro each.

Right now, a ticket from Paris city to Yerres costs 2.50 EUR, so a t+ ticket is no good and you need to buy separate tickets. Also, I am unsure about any child discount and the ages. And is this just for the day with a return? Do you need a bus from Yerres RER station to your actual destination?

From CDG to your lodging in Paris with 7 people and luggage you should use a taxi -- at the taxi stand tell the dispatcher how many you are and where you are going and they will assign you to a minivan-sized taxi.

For metro and t+ tickets get Navigo easy cards and as you say add 10 rides at a time to them using the Mobilites app, that way it will be about $2 or less per ride. Note that you can transfer within the Metro system as much as you need/like for one ride, but each time you board a bus it costs a ride whether you have to take one bus or three to get to your destination. (So favor metro all else being equal)

Lee,
Please, listen to JHK and janettravels. Take two taxis to your hotel. It is worth the extra euros. Plan for that in your travel budget.

the thing is -- IT IS CHEAPER TO TAKE A CAB WITH THIS MANY PEOPLE. You will be under the ratp.fr rules for 2025+ assuming the trip is after Jan 1 -- a ticket via metro/RER anywhere in the Ile de france will cost 2.50 and bus tickets 2. There are no more t+ ticket nor carnets of tickets. the airports are exceptions to the 2.50 ticket prices -- both airports will cost 13 Euro coming or going.

Thank you all - I had not even considered a taxi but it makes sense. Apologies for leaving out details. Our trip is late May, we'll be arriving on a Tuesday early afternoon. The adults have all traveled to western or eastern Europe before, several times. The kids not at all. Kid ages range from 5 to 13, two girls (older) and the young boy. Jet lag is a certainty but we'll plow through Tuesday as best we can. It's worth the expense (or savings!) to take one or two taxis from CDG to our Paris destination. We completely ascribe to the RS travel light mode, in fact two of our Christmas gifts to my daughter and son-in-law (our traveling partners) were RS bags! So each traveler gets a day pack and either an RS bag (adults) or a small duffle (kids). So not overburdened with luggage.

We're comfortable with the Metro, no experience with buses. The Yerres trip is to pick up 2 campervans and the proprietor has provided some instruction on getting there. Wondering if a cab trip there would be an option...

I would work with my hotel to hire a car service for pick up at the airport. We did that last year for the two of us and the van that picked us up could accommodate 7 passengers. It relieves so much stress and probably won't cost much more if any than taking 2 cabs.

there are mini vans in the airport cab line and it is no trouble to just get one without paying the extra charges a private hotel hire will cost or run the risk of. a late plane and added costs.

What Janet said. Taxis from the official line are simple, efficient and reliable.

We arrived early at CDG and after clearing customs and passport control we found that there are taxis that will take you where you want to go for a fixed price, 55 euros is what we paid, and the driver took us to the airbnb apartment we were renting in the area near the Arc d'Triomphe. I had planned to try to ride the Metro and buses if needed but since we had jetlag and were pretty tired the fee was a bargain and we considered it money well spent. After you settle in you can learn more about navigating the Metro system from friendly people in the Metro stations. You can find the taxis stationed in one convenient place with bilingual signage telling you about the fixed charge.

Paris also has Uber fyi. We stayed at the Hilton CDG after a late flight and Ubered into the city the next day. It was about the same cost for our family of 4 as taking the train would have been, if I recall correctly, plus we didn’t have to hump our luggage back to and from the train station.

Once in the city it’s easy to buy metro tickets from the machines; they all have an English option.

problem with uber is they can't use the bus lanes - taxis can. uber is slower than taxi in traffic
