Key facts at a glance

Seven key data points, one picture: CDG is a large, busy airport that has grown steadily over five decades.

How do I get from Charles de Gaulle Airport to the city centre?

RER B train

• Fast and reliable: The RER B line runs directly from CDG to Gare du Nord in about 35 minutes (Paris Aéroport train page).
• A single ticket costs €11.80 as of 2025 (RATP official fare site).
• Trains run every 10–15 minutes from about 5 AM to midnight.

Roissybus

• Direct service from CDG to Opéra in central Paris every 15 minutes (Paris Aéroport bus page).
• Journey time: 60–70 minutes depending on traffic.
• Ticket price: €13.70 (2025), purchased at the bus stop or online.

Taxis and ride-hailing

• Flat-rate to Paris: €35 for Right Bank (Paris intra-muros), €35 for Left Bank as of 2025 — officially set by Paris Aéroport (Paris Aéroport taxi page).
• Ride-hailing services like Uber and Bolt operate from designated pick-up zones but charge dynamic pricing.
• Estimated cost via Uber: €35–€55 depending on demand and destination (Uber Paris city page).

Private transfer services

• Pre-booked private cars from CDG to central Paris start around €55–€70 for a sedan (Paris Aéroport private transfer page).
• Best for groups of 3+ or when carrying lots of luggage.

Cheapest option breakdown

The RER B train at €11.80 is the cheapest way into Paris — by a significant margin. Roissybus at €13.70 costs slightly more but drops you closer to the commercial centre. Taxis and private transfers offer door-to-door convenience at 3–5 times the cost. No free shuttle to the city exists (Paris Aéroport access page).

The implication: most travellers should weigh the cost savings of the RER B against the door-to-door convenience of a taxi, especially for late-night or luggage-heavy trips.

Can you walk between terminals in Paris airport?

Terminal 1 and Terminal 3 connection

• Walking between Terminal 1 and Terminal 3 is not possible — you must use the CDGVal automated shuttle (Travel Vient CDG guide).
• CDGVal is free, runs 24/7, and connects all three terminals plus parking lots.

Terminal 2 internal connections (2A-2G)

• Terminal 2 is split into sub-terminals 2A through 2G, connected by walkways and shuttle buses (Paris Aéroport terminal maps).
• 2A to 2F are linked via walkways; 2G requires a dedicated shuttle bus (Travel Vient CDG guide).

CDGVal automated shuttle

• Free, 24/7 service connecting Terminals 1, 2, and 3 (Paris Aéroport shuttle page).
• Journey time: about 8 minutes between Terminal 1 and Terminal 2.

Walking distances and time estimates

• Same-terminal transfers: approximately 15 minutes (Travel Vient CDG guide).
• Different-terminal transfers: allow 1 hour.
• Domestic-to-domestic connections: about 30 minutes.
• Domestic-to-international connections: about 1 hour.
• International-to-domestic connections: about 1 hour 30 minutes.

The pattern: even with the CDGVal, transfer times at CDG are longer than at many other European hubs, so plan accordingly.

How long does it take to get through security at Charles de Gaulle?

Average wait times by terminal

• Terminal 1: 15–25 minutes at peak hours, 1–14 minutes at minimum (AirlineAirport CDG security wait times).
• Terminal 2: 1–10 minutes normally, 20–25 minutes at peak (Paris CDG International Airport security fast-track guide).
• Terminal 3: generally under 10 minutes (AirlineAirport CDG security wait times).
• Terminal 2E reportedly has the longest lines.

Peak hours and seasonal factors

• Peak periods: 6–9 AM and 5–8 PM daily (Paris Aéroport security wait times page).
• Summer (June–August) and holiday seasons see longer average waits.
• Security queues can surge to 45–60 minutes during peak holiday travel weeks (Paris Aéroport security wait times page).

Tips to speed through security

• Book the optional fast-track service (from about €10–€15) to reduce waits to 5–10 minutes (AeroGreet CDG fast-track guide).
• Use PARAFE biometric e-gates for EU/Swiss/Norwegian passport holders; they process passengers in under 12 seconds when functioning (AeroGreet VIP services guide).
• Pack liquids in a single resealable bag and wear shoes that are easy to remove.

TSA PreCheck equivalent (not applicable)

There is no CDG equivalent to the US TSA PreCheck scheme. The fast-track option is pay-per-use and widely available across all terminals.

The catch: knowing your terminal and departure time can save you 15–20 minutes of waiting, so choose your flight and terminal wisely.

Is Charles de Gaulle the biggest airport in Europe?

Size by passenger traffic

• CDG handled 67.4 million passengers in 2023, making it the second busiest in Europe after Heathrow (79.1 million) (Wikipedia list of busiest airports in Europe).
• In 2019, before the pandemic, CDG processed 76.8 million passengers.

Size by land area

• CDG covers about 32 square kilometres, making it larger in land area than Heathrow (12.27 km²) (Wikipedia Charles de Gaulle Airport).
• Schiphol covers about 27 km².
• CDG has four runways; Heathrow has two.

Comparison with Heathrow and Amsterdam Schiphol

Heathrow handles more flights and more passengers annually, but CDG has more terminal space and a larger physical footprint. Schiphol is more compact and generally considered more efficient for transfer connections (Wikipedia Schiphol Airport).

Future expansion plans

A proposed Terminal 4 at CDG has been discussed but remains in planning stages, with no confirmed timeline for construction (Wikipedia Charles de Gaulle Airport).

The pattern: while CDG wins on raw size, Heathrow wins on passenger throughput, which affects transfer times and queue lengths.

Can I stay overnight at Charles de Gaulle Airport?

Airport lounges with sleep facilities

• Several lounges (e.g., Air France, Star Alliance) have recliners and quiet zones (Paris Aéroport lounges page).
• Priority Pass holders can access lounges in Terminals 1 and 2.
• No dedicated sleep pods exist at CDG as of 2025.

Sleeping areas inside terminals

• Airside sleeping is permitted but seating is limited — no padded benches at most gates (Sleeping in Airports CDG guide).
• Terminal 2 in the early morning hours (midnight–5 AM) empties out significantly.
• Security may ask for a boarding pass during night hours (midnight–5 AM).

Nearby hotels (connected by CDGVal)

• Sheraton Paris Airport Hotel — connected to Terminal 2 (Marriott Sheraton page).
• Novotel Paris Charles de Gaulle Terminal — accessible via CDGVal from Terminal 3 (Accor Novotel page).
• ibis Styles and citizenM hotels are also within the airport zone, connected by free shuttle.

Safety and comfort considerations

• CDG is generally safe overnight, but travellers report feeling comfortable only in well-lit areas near security (Sleeping in Airports CDG guide).
• Airside areas require a valid boarding pass for the following day.
• 24-hour food options are limited: some vending machines and a McDonald’s in Terminal 2 are available.

The implication: if you have a long layover, plan to spend €80–€150 for a hotel rather than trying to sleep on a terminal bench.

Verified vs. unverified: What’s settled and what’s not

The pattern: confirmed facts are backed by official sources, while the unclear items rely on user reports and official uncertainties.
