Quick Answer
The best way from Charles de Gaulle Airport (CDG) to Paris for most people is the RER B train: a flat €14, about 25–40 minutes to the centre, and unaffected by road traffic. With a group or heavy luggage, a taxi at the fixed fare (about €56 to the Right Bank, €65 to the Left Bank) is often better. There is no direct metro to CDG — the RER B is the fast rail link, and you change to the metro at your Paris station.

Is there a metro to CDG?
No direct metro line reaches CDG. The rail link is the RER B, a regional express train that runs into central Paris where you can change to the metro. When people search "CDG airport metro," the RER B is the answer. (Metro Line 14 serves Orly, not CDG.)
Option 1: RER B train — best for most travellers
The RER B is the fastest, most reliable public route because it does not sit in A1 motorway traffic.
- Cost: a flat €14 with the "Paris Région ↔ Aéroports" ticket. The same ticket lets you continue onto the metro to your final station, since rail-to-rail transfers are valid for 2 hours — so you usually buy just one ticket.
- Time: about 25–30 minutes to Gare du Nord, a little more to Châtelet–Les Halles and Saint-Michel–Notre-Dame.
- Frequency: roughly every 10–20 minutes.
- Hours: from CDG towards Paris, roughly 4:50 am to 11:50 pm.
Where it connects to the metro: - Gare du Nord — Metro 4 and 5; RER D and E. - Châtelet–Les Halles — Metro 1, 4, 7, 11, 14; RER A and D. - Saint-Michel–Notre-Dame — Metro 4; RER C. - Denfert-Rochereau — Metro 4 and 6.
Watch your bags. The RER B is a known spot for pickpockets. Keep valuables in a front pocket. For how the €14 ticket works, see Paris metro tickets.
How to take the RER B from CDG
- Follow signs for "Paris by train / RER B" from your terminal (use the free CDGVAL shuttle if you need to move between terminals).
- Buy the €14 airport ticket at a machine or in an app; load it on a Navigo Easy card or your phone.
- Tap in at the gate, and check the platform screen shows a Paris-bound train.
- Get off at the station that best connects to your hotel, and change to the metro on the same ticket.
Option 2: Taxi at the fixed fare — best with luggage or a group
Official Paris taxis charge a fixed price by law: about €56 to the Right Bank (north of the Seine) and €65 to the Left Bank (south). It is per car for up to four people, with no meter and no separate night or Sunday surcharge on this flat rate. A family or group often pays less than four train tickets and travels door to door.
Use only the official taxi queue outside the terminal. Ignore anyone offering a ride inside the building.
Option 3: Bus 9517 + Metro 14 — good value, one change
Bus 9517 runs from CDG to the Saint-Denis-Pleyel hub in about 30 minutes for a €2.05 Bus-Tram ticket. There you change to Metro Line 14, which reaches central Paris in about 10 minutes. It is cheap and fairly quick, but it needs a transfer, so it suits travellers with light luggage.
Option 4: Buses 350 and 351 — cheapest by day, but slow
Local RATP buses cost just €2.05 but take 60–90 minutes and have no luggage racks: - Bus 350 runs to Porte de la Chapelle (Metro 12), passing Gare du Nord and Gare de l'Est. Roughly 05:40–22:30. - Bus 351 runs to Nation (Metro 1, 2, 6, 9; RER A). Roughly 05:30–21:40.
Choose these only if you are on a tight budget, travel light and have time.
Option 5: Private or shared transfer — door to door
Shared shuttle vans start around €16–18 per person; a private transfer takes your whole group directly to the hotel. Both are booked in advance and are handy with children, heavy luggage, or trips to Disneyland Paris.

Which should you choose?
- Solo or couple, light luggage: the RER B (€14). Fast, cheap, reliable.
- Family or group of 3–4: a taxi at the fixed fare — usually cheaper per person and far easier with bags and children.
- Tight budget, time to spare: bus 9517 + Metro 14, or buses 350/351.
- All-zones Navigo pass holder: the RER B at no extra cost.
- Late arrival, or Disneyland: a private transfer or a taxi.
Late-night and early-morning arrivals
The RER B from CDG stops around 11:50 pm and restarts before 5:00 am. In that window:
- Noctilien night buses N140 and N143 link CDG with Gare de l'Est (via Gare du Nord) for a few euros, roughly between midnight and 5 am. N143 is faster (about an hour); N140 takes longer.
- A taxi at the fixed fare or a pre-booked transfer is simpler, especially with luggage.
- Note that CDG terminals and stations are largely closed between about 1:00 and 5:30 am, so plan where to wait.
What's coming: CDG Express
A new direct train, CDG Express, is due to open on 28 March 2027. It will link Gare de l'Est to CDG Terminal 2 in about 20 minutes for around €25, every 15 minutes. It is not running yet, so ignore any site that presents it as available today.
Common mistakes
- Looking for a metro to CDG. There is none; take the RER B and change to the metro in Paris.
- Buying a normal €2.55 ticket for the train. Airport journeys need the €14 ticket.
- Taking a taxi from someone inside the terminal. Use only the official outside queue.
- Relying on the RER B after midnight. It has stopped; use a Noctilien bus, taxi or transfer.
- Taking buses 350/351 with big suitcases. They are slow and have no luggage space.
Conclusion
For almost everyone, take the RER B from CDG: €14, about 30 minutes, and no traffic — then continue to your metro stop on the same ticket. Switch to a fixed-fare taxi when you have a group, heavy luggage, children, or a late-night arrival. Keep the cheap buses for tight budgets with time to spare, and remember CDG Express is a 2027 option, not a 2026 one.
