Paris Charles de Gaulle Airport Layover Guide
CDG is a major Air France hub with three terminals linked by the CDGVAL shuttle. Transfers can be complex, but the RER B reaches central Paris for longer layovers.
Minimum connection time: 90 minutes (more between terminals) · Best for: Schengen connections
Quick answer
CDG is sprawling and transfers can be confusing — give yourself time. Lounges and a YOTELAIR help on long waits. With 6+ hours and Schengen entry, the RER B reaches central Paris in about 35 minutes, but allow generous buffers.
Paris Charles de Gaulle (CDG) is a major European gateway with good rail links to the city, but it's a large, multi-terminal airport where connection time and Schengen rules matter. Most travellers transit airside freely, while leaving to see Paris requires Schengen entry — covered in our Schengen transit guide. With a long daytime layover and the right status, central Paris is reachable by train, though CDG's size means allowing time to navigate.
- Leaving means entering Schengen — see our Schengen transit guide.
- The RER B train links CDG to central Paris.
- CDG is large with separate terminals — allow time for connections.
- For waits and overnight stops, see our lounge and hotel guides.
Transit overview
CDG's three terminals — especially the lettered halls of Terminal 2 — are notorious for confusing connections. The CDGVAL automated shuttle links the terminals, and you may need buses for some transfers, so a 90-minute minimum is wise and two hours is safer for tight itineraries.
For rest, the YOTELAIR at Terminal 2E is the reliable airside cabin option, and Air France and Priority Pass lounges offer food, showers and quieter seating. Free sleeping spots are limited.

- Terminal 2 halls can be confusing — read signs
- YOTELAIR at T2E for airside rest
Going into Paris
The RER B train runs from CDG to central Paris (Gare du Nord, Châtelet) in around 35 minutes. With 6+ hours and Schengen entry clearance, a quick visit is possible, though the return — RER plus security plus a confusing terminal — eats time, so be conservative.
Confirm whether you need a Schengen visa or ETIAS authorisation before planning to leave the airport.
Should you leave CDG on a layover?
Central Paris is reachable by the RER B train in well under an hour, so with about seven hours or more and Schengen entry permission, a quick visit is feasible. With less time — or if you're not eligible to enter Schengen — CDG's lounges and rest areas are the better option. Our CDG-to-Paris transfer guide covers the RER, buses and taxis.
- Under ~6 hours: stay airside; CDG is large to navigate.
- 7+ hours: central Paris is reachable by RER B.
- Confirm Schengen entry eligibility before leaving.
Connecting within CDG
