So, update from my experiences...

G7 wanted €43 for a pickup from Gare du Nord to the 3e, which is just silly. No easily hailed G7 Kids cabs on arrivals, so we took a bus from the GdN bus station (very handy to know that place) to our apartment, nearly door to door, and not much longer, given the silly post-€* taxi queues. Loads of space for buggies and wheelchairs on board.

Had less time today so took the metro across town this morning. Easier than I thought, but getting the gate opened for the pushchair was not obvious (even less so if I didn't speak French). Unfortunately I chose a station with loads of steps down, but I'm used to that. There were escalators where we arrived, and I'm used to that too. Plenty space on board the newer trains.

The buses failed us later due to the snow (lightweights!) but the G7 app got us a car seat taxi in a few minutes, which was a huge relief. Price was reasonable, considering.

So, pretty easy, all told!

But you can change to the RER at St. Michel or Chatelet @:-)

Or indeed the Tram at Villejuif Louis Aragon, if you feel that way inclined.

G7 uses meters only unless you are going to either CDG or ORY. There is no way to know the exact price in advance and it certainly would not be 43€.

Did you go to the official taxi queue on the west side of the building near the Eurostar arrival platforms or did you go out front of the station?

The €43 was for a station prebooking, through the app, to meet them at rue de Dunkerque, and was quoted as a minimum fare for the service.

We were among the last off the train (as we had a baby with us, a pushchair and all associated paraphernalia) so the official Eurostar queue was massive. The app was showing a long wait for a child seat taxi on demand, so we decided to take the bus, not least because it was -2°C, the train was late, and the baby needed to sleep!

The taxi queue moves rather quickly but I can imagine the additional complications of traveling with a young child.

If you are using apps as a transportation solution, you may want to consider either of the two many in Paris are now using:

Chauffeur Privé

Taxify

Yes, but many reading here are learning, Looking for signs to Metro at either airport will yield nothing. And following signs to and getting on the Metro in Paris will be worse.

I did look into those, but the difficulty is that, unlike licenced taxis, the VTC services aren't allowed or insured to carry children without the proper car seat in place, although some will (but I'm not sure I'd want them to). Some services say they are "working on" baby-friendly cars on request, but most point to the fact they have Isofix points on seats.

​​​​​​Which is fine if you live in Paris, or have a child under 1 who can use a travel system, or an older child who can use a portable booster seat. But we fit none of these categories

But it was no hassle to buy a carnet (we were going to anyway), jump into the lift up to the bus deck, ask the driver to open the middle doors and get on. It's what I do at home. Total price, €3, nice tour of Gare de l'Est, Porte Saint Martin and Musée des Arts et Métiers included. If I'd known it was going to be that easy, I'd have planned to do it that way from the outset!

Anyway, to follow up, ordered a G7 Kids on the app this morning to catch the train back from Gare du Nord and it worked a treat. Lovely driver once again. I guess it takes a certain type to want to have baby seats in the car!

It's all one big train ride to me............Metro/RER............

Another one on the ignore list.

Ach, sometimes things get lost in translation. RER/Metro is an important distinction (at a minimum, you need to remember to have your ticket ready for exit on the RER...) Perhaps the distinction is reinforced in Paris where the Metro was deliberately built to be incompatible with the mainline rail networks (narrow loading and track gauge, right-hand running) to avoid a scheme where all the mainline termini were to be destroyed at the lines interconnected underground as an alternative to the metro. There is also the slightly odd situation with RER line B (the main way of reaching both airport, unless you have a particular desire to use Pont de Rungis) where it is run by the SNCF (national rail authority) north of the Gare du Nord (so, to CDG) and by the RATP (regional transport authority, pronounced "rat-pee") south of it (so, to Antony for ORY).

Details, sure. But nobody wants you to get lost...

Hello,
I use uber for a very long time when I'm in Paris and I have always been satisfied with the service. The drivers are always on time, the prices are really not excessive, always smiling and very convenient compared to taxis who do not want to take you somewhere because it is too far or there is too much snow
