Paris Charles de Gaulle Airport to Paris City Centre (Gare du Nord)

Here is the thing no queuing tout at the taxi rank will ever tell you: the fastest, cheapest, most gloriously reliable way from Charles de Gaulle into the centre of Paris costs exactly €14 and runs straight to Gare du Nord. That's the RER B, the workhorse commuter line every Parisian who commutes from the northern suburbs rides without a second thought. CDG sits roughly 23 km northeast of the centre, and while the touts will try to talk you into a fixed-fare cab, I'll happily argue you onto the train — because for a solo traveller with a rucksack, nothing else comes close.

Why €14 buys you the whole city

Let's be clear about what that flat fare actually gets you. The RER B airport ticket is €14 (children aged nine and under travel for €7), it covers zones 1 to 5, and it runs direct to Gare du Nord in around 35 minutes. Trains leave roughly every 10 to 20 minutes from early morning until past midnight — call it just before 05:00 through to a shade past 00:15 — so unless you land at some ungodly hour, there's almost always one waiting.

The masterstroke, though, is the transfer. That single ticket stays valid for two hours and includes your onward metro connections. So you don't just arrive at Gare du Nord — you dissolve into the Paris network from there, no second ticket, no fumbling at a machine with your luggage wedged between your ankles. Board at the RER stations under Terminal 2 or over at T3/Roissypôle, and you're operated by the RER B (RATP/SNCF), the same line the locals trust morning and night. Europe's busiest railway station happens to be your front door, and every arrondissement is a metro hop away.

The €56 cab — and when it actually proves its worth

Now, I'm not going to pretend the official taxi is a rip-off, because Paris did something genuinely sensible here: the fare is fixed by law. It's €56 to any Right-Bank address, €65 if you're crossing to the Left Bank, and that price holds 24/7 for up to four passengers with luggage included. No meter roulette, no "the traffic, monsieur" surcharge at the end. Grab it only from the official rank at each terminal — never, ever from someone approaching you in the hall — and you'll roll door to door in about 40 minutes.

So when does the cab beat my beloved train? When you're four people splitting the bill (suddenly it's €14 a head — a wash). When you land at 02:00 and the RER has stopped. When you've a suitcase the size of a wardrobe, a bad knee, or a hotel down some cobbled lane the metro doesn't reach. For a couple with heavy bags heading Left Bank, the taxi is honest value. For everyone else? The €14 train wins on price, and often on time too, because it sails past the périphérique traffic that leaves cabs stewing.

The budget bus, the pre-booked driver, and one thing that's gone

A quick word on the alternatives, because misinformation abounds. First, forget the Roissybus — it was withdrawn in early 2026 and no longer exists, whatever an out-of-date guidebook tells you. In its place is the RATP Bus Express, route 9517, running from the Roissypôle bus station for €2.05–2.55. It sounds temptingly cheap, but there's a catch: it changes at Saint-Denis-Pleyel and needs a separate metro ticket to finish the job — roughly €4.60 all in — and takes about 55 minutes. Cheapest on paper, fiddliest in practice. I'd only bother if I were counting every centime.

If you'd rather have a fixed price and a driver tracking your flight, a pre-booked private transfer (Welcome Pickups, Blacklane and the like) runs €60–80, meets you in arrivals, and delivers you door to door in about 40 minutes — a soft landing after a red-eye. And hiring a car (Hertz, Avis, Sixt at the T1/T2/T3 rental centre, €45–90 a day) makes sense only if you're pressing on beyond Paris — central parking is punishingly expensive and the streets are no place to learn to drive on the right.

How a streetwise arrival actually plays it

Here's my routine, and I've done it more times than I can count. Follow the RER signs the moment you clear customs, buy the €14 ticket, and keep it in your hand — you'll feed it back into the barrier at Gare du Nord and again at your metro change, so don't bury it in a pocket. Ignore anyone who intercepts you before the official rank or the ticket machines; the genuine taxi queue and the RER are both clearly signed. And a small warning: CDG Express, the dedicated fast link everyone keeps promising, doesn't open until 2027, so don't go hunting for it. Until then, the RER B is the sharp local move — €14, 35 minutes, straight to the middle of everything.
