Paris to CDG Airport: How to Get There — Train, Taxi & Private Transfer
Every realistic option for getting from Paris to CDG in 2026 — RER B train, private transfer, official taxi and bus — with honest journey times, current prices, and a clear recommendation for each type of traveller.
Jul 31, 2026
Quick summary
Getting from Paris to CDG airport in 2026 comes down to four options: the RER B train (€14 airport ticket, 35–50 minutes, fastest for standard daytime departures with light luggage), a private KAR GO transfer (from €100 per vehicle in a Mercedes E-Class for up to 3 passengers, or €130 in a V-Class for up to 7 — door-to-door with a driver who builds in a traffic buffer), the official taxi at a legally fixed rate (€56 from the Right Bank, €65 from the Left Bank), and the express bus 9517 that replaced the Roissybus in March 2026. The key variable when leaving Paris is time pressure: missing a flight costs far more than any transfer, so early departures, heavy luggage or a hotel far from the RER B all shift the decision toward a pre-booked private transfer or taxi.
Getting from Paris to Charles de Gaulle Airport (CDG) is the journey most travellers think about least and stress about most. You know the city well by the time you leave — you have navigated the metro, found the good bakeries, survived the queues at the Louvre. And then comes the morning of departure.
This guide covers every realistic option for getting from Paris to CDG in 2026: the RER B train, private transfer, official taxi, and bus. For each, we give honest journey times, current prices, and a clear recommendation for different types of traveller.

Paris to CDG Airport — All Options at a Glance
| Option | Price (2026) | Journey time | Best for |
|---|---|---|---|
| RER B Train | €14/person (airport ticket) | 35–50 min from central Paris | Solo travellers, light luggage, daytime departures |
| Private Transfer (KAR GO) | From €100 (E-Class, up to 3) · from €130 (V-Class, up to 7) | 45–75 min door-to-door | Families, groups, business, early-morning flights |
| Official Taxi (fixed rate) | €56 (Right Bank) / €65 (Left Bank) | 45–75 min (traffic-dependent) | Comfort, 2–3 people, last-minute bookings |
| Express Bus 9517 | €2.05/person | ~30 min from Saint-Denis-Pleyel (+ metro/RER to reach it) | Budget travellers near metro 13/14 or RER D |
A note on the bus: the Roissybus, which ran from Opéra to CDG for 34 years, was discontinued on 1 March 2026. Its replacement is the express line 9517, which leaves from the Saint-Denis-Pleyel hub (metro lines 13 and 14, RER D) and costs a standard €2.05 bus ticket — much cheaper than the old Roissybus, but no longer a direct link from central Paris.
The key variable when travelling to CDG — as opposed to from it — is time pressure. Missing a flight is a different kind of stress to missing a connection. If your flight departs before 8:00 AM, or if your hotel is not on a direct RER line, the calculus shifts toward private transfer or taxi. If you have a 10:00 AM departure from central Paris with light luggage, the RER B is still the fastest and cheapest option.
The RER B Train — Fastest for Standard Departures
The RER B connects central Paris to CDG in 35–50 minutes depending on your starting station. It runs from multiple central Paris stops — Gare du Nord, Châtelet–Les Halles, Saint-Michel Notre-Dame, Denfert-Rochereau — making it accessible from most Paris arrondissements without needing a taxi to the station first.
The fare in 2026 is €14 per adult with the dedicated 'Paris Région <> Aéroports' ticket (€7 at the reduced fare). Important: the standard €2.55 Métro-Train-RER ticket is not valid at the CDG airport stations — you need the airport ticket, sold at machines and via the Île-de-France Mobilités app.
Which RER B direction to take
At Gare du Nord, check the destination board carefully. RER B trains split at the northern end — trains towards CDG are marked 'Aéroport Charles de Gaulle 2 TGV' or 'Mitry-Claye'. Make sure you board the correct service, as the two branches diverge after Le Bourget.
Journey times from key Paris stations
| Departure station | Approx. journey time to CDG |
|---|---|
| Denfert-Rochereau (14th arr.) | ~50 minutes |
| Saint-Michel Notre-Dame (5th arr.) | ~45 minutes |
| Châtelet–Les Halles (1st arr.) | ~42 minutes |
| Gare du Nord (10th arr.) | ~30 minutes |
When the RER B is the wrong choice
The RER B becomes problematic in three situations. First, very early morning departures (before 6:00 AM) — frequency drops significantly and you cannot afford a delayed train. Second, if you are travelling from a hotel not near an RER B station — taking a taxi to Gare du Nord, then the RER to CDG, is rarely faster than a single private transfer. Third, with significant luggage: navigating stairs with large suitcases at rush hour is genuinely difficult, and platforms at Châtelet–Les Halles are a long walk from street level.
Private Transfer from Paris to CDG — The Stress-Free Departure
A pre-booked private transfer from your Paris hotel or apartment to CDG is the option that removes the most variables from your departure morning. Your driver arrives at the agreed time, helps with luggage, and drives directly to your terminal.
How it works with KAR GO
- You specify your terminal number and flight time at booking
- Your driver arrives at your hotel door at the agreed time with enough buffer for traffic
- Direct drive to your departure terminal — no intermediate stops
- Driver handles luggage loading and unloading
- Fixed price confirmed at booking — no surge, no meter
- Free cancellation up to 24 hours before pickup
Paris to CDG — 2026 private transfer prices
Two vehicle classes cover most needs: the Mercedes E-Class sedan for up to 3 passengers, and the Mercedes V-Class van for up to 7 passengers and 7 full-size suitcases. The price is per vehicle, not per person, and covers all luggage.
| Pickup location | E-Class (up to 3 pax) | V-Class (up to 7 pax) |
|---|---|---|
| Central Paris (hotel or apartment) → CDG | From €100 | From €130 |
| Disneyland Paris → CDG | From €90 | From €120 |
| Orly Airport → CDG (inter-airport) | Fixed quote at booking | Fixed quote at booking |
When to book a private transfer vs. taking the RER
For a group of 3 or more passengers, the per-person economics are similar or better than individual RER tickets plus any metro cost to reach the RER station. The private transfer is almost always the right choice for: early morning departures (5:00–7:00 AM), families with children, business travellers with tight connections, guests staying in hotels not near RER B stations, and anyone travelling with ski equipment, sports gear, or more than two large suitcases.
Official Taxi — The Flexible On-Demand Option
Paris taxis charge a fixed rate to CDG regardless of traffic — a legal requirement since 2016. The 2026 rates are €56 from the Right Bank (north of the Seine) and €65 from the Left Bank (south of the Seine). These apply 24 hours a day, 7 days a week, with no supplements for luggage, night travel, or weekends.
Taxi vs private transfer — the practical differences
| Factor | Official Taxi | KAR GO Private Transfer |
|---|---|---|
| Booking | Hail on street or app (G7) | Pre-book online or by phone |
| Vehicle | Standard sedan (4 pax max) | Mercedes E-Class or V-Class (up to 7 pax + luggage) |
| Flight-time buffer | Your responsibility to allow time | Driver monitors your schedule |
| Price to CDG (Right Bank) | €56 fixed | From €100 (E-Class) · from €130 (V-Class, up to 7 pax) |
| Luggage assistance | Driver may help, not guaranteed | Included as standard |
| For groups of 5+ | Two taxis required | One vehicle, one price |
For 1–2 passengers with standard luggage, an official taxi is a perfectly reasonable choice. For 3 or more passengers, or anyone with large luggage, the maths and the convenience both favour a private transfer. Use the G7 app to book an official taxi in advance — it provides a confirmed vehicle and eliminates the risk of a long queue at the taxi rank on your departure morning.
Special Routes — Disneyland Paris to CDG and Inter-Airport Transfers
Disneyland Paris to CDG Airport
Disneyland Paris is 35 kilometres east of CDG — actually closer to the airport than central Paris. By private transfer, the journey takes 30–45 minutes and costs from €90 per vehicle (Mercedes E-Class, up to 3 passengers; from €120 in a V-Class seating up to 7). By public transport, you would need the RER A from Marne-la-Vallée Chessy to Châtelet–Les Halles, then change to the RER B northbound — approximately 75–90 minutes total with luggage. For families leaving Disneyland for a morning flight, a direct private transfer is the obvious choice. See our Disneyland Paris to CDG private transfer page.
Orly Airport to CDG Airport (inter-airport)
If you have a connecting flight from Orly to a CDG departure, the fastest route is a private transfer between the two airports — approximately 45–60 minutes bypassing central Paris entirely, with a fixed quote confirmed at booking. Public transport requires the Orlyval to Antony, then RER B north — approximately 1h15 minimum with the connection wait.
From outer Paris or suburbs to CDG
If you are staying in Montparnasse (14th–15th arr.), the RER B involves taking the metro first to Denfert-Rochereau or Saint-Michel. Journey time is 50+ minutes on the RER alone. A private transfer from Montparnasse to CDG takes 50–70 minutes by road and door-to-door — comparable in total time, significantly more comfortable.
How Much Time to Allow — Paris to CDG
CDG operates timed security and check-in requirements that differ by airline. The minimum times below are practical guides, not guarantees:
| Flight type | Recommended arrival at CDG | Leave Paris (private transfer) | Leave Paris (RER B from Gare du Nord) |
|---|---|---|---|
| Short-haul European (easyJet, Vueling, Air France domestic) | 90 min before departure | 2h 15 min before departure | 2h before departure |
| Long-haul intercontinental (Air France, Delta, Emirates) | 2h 30 min before departure | 3h 15 min before departure | 3h before departure |
| Early morning flight (before 8:00 AM) | Add 30 min for reduced RER frequency | Strongly recommend private transfer | Check RER schedule the night before |
One practical note: CDG Terminal 2 is large and walking between check-in and gates can take 20–30 minutes at peak times. The time at CDG is rarely wasted — it is the time getting there under pressure that causes problems. Buffer generously.

Key takeaways
- The RER B is the fastest and cheapest option for standard daytime departures: €14 per adult (the dedicated airport ticket — the standard €2.55 metro ticket is not valid at the CDG stations), 35–50 minutes from central Paris.
- A private KAR GO transfer is from €100 per vehicle (Mercedes E-Class, up to 3 passengers) or €130 (V-Class, up to 7) — fixed price confirmed at booking, hotel-door pickup with a traffic buffer built in, and direct drop-off at your departure terminal.
- Official Paris taxis charge a legally fixed rate to CDG: €56 from the Right Bank, €65 from the Left Bank — 24/7, no luggage or night supplements. Book via the G7 app to avoid queuing on your departure morning.
- The Roissybus was discontinued on 1 March 2026. Its replacement, the express bus 9517, runs from Saint-Denis-Pleyel (metro 13/14, RER D) to CDG for a standard €2.05 bus ticket.
- For flights departing before 8:00 AM, reduced RER frequency makes a pre-booked private transfer or taxi the safer choice — a delayed train is a risk you cannot absorb on departure day.
- CDG Terminal 2 is enormous: walking from check-in to the gate can take 20–30 minutes at peak times, so buffer generously — arriving early at CDG is rarely wasted time.
