A Paris layover can genuinely work, but it depends heavily on which airport you land at and how much time you actually have once immigration and transfers are accounted for. Charles de Gaulle (CDG) has a direct train into the centre; Orly requires an extra connection. With a solid block of hours, either can get you to the Eiffel Tower or a stretch of the Seine and back — with a short one, it's genuinely not worth the risk.
Can you leave the airport? The Schengen question
France is part of the Schengen area, so if you're arriving from outside Schengen, leaving the airport counts as entering the zone, which for many nationalities is visa-free for short stays but draws on the same 90-days-in-any-180-days allowance that covers your whole Schengen trip — see our Schengen 90/180 rule guide for how that's calculated. If you're transiting between two Schengen flights without formally entering the zone, this generally doesn't apply, since you never clear immigration. Requirements vary by nationality and change over time, so confirm your specific situation with the European Commission's official guidance or your government's travel advice before you fly.
How much time you need
CDG is one of the busiest hubs in Europe and immigration queues can be long at peak times, particularly for non-Schengen arrivals. As a rough guide, from CDG:
- Under about 5 hours: Tight. You may reach central Paris and see very little before needing to turn back — many travellers prefer to stay airside on a layover this short.
- 5–8 hours: Workable for a focused trip to one or two central sights, provided immigration moves at a normal pace.
- 8 hours or more: A comfortable half-day, enough for a proper walk along the Seine and one major sight.
From Orly, add roughly 45 minutes to an hour to each of these bands to account for the extra connection into the RER network. These figures are indicative only — actual safe timing depends on your ticket, immigration queues on the day, and how far you stray from the station. For general guidance on judging whether a connection is workable at all, see our guide to minimum connection times. If your flights are on two separate tickets rather than one through-booking, read our guide to self-transfer flights first.
Getting from CDG into the city
The RER B suburban express train runs directly from CDG to central Paris (Gare du Nord, Châtelet-Les Halles) in around 35–50 minutes depending on the service, making it the fastest and most predictable option, since it avoids Paris's often heavy road traffic. Tickets can be bought from machines in the station. A taxi is available and has a flat-rate fare structure for central Paris, but is far more exposed to traffic delays, which makes it a riskier choice with a tight layover.
Getting from Orly into the city
Orly is further from central Paris and doesn't have a direct RER station on-site. The most reliable option is the Orlyval automated train to Antony, connecting onto the RER B, or the newer direct metro/tram links depending on current service — check what's operating at the time of your trip, since Orly's connections have been upgraded in recent years. Budget extra time for this connection compared with CDG, and treat Orly layovers with more caution on a tight schedule.
A realistic layover itinerary
With around 7 hours clear after immigration and a return buffer, via CDG:
- Take the RER B to Châtelet-Les Halles — allow up to an hour including the walk to the platform and any delays.
- Walk along the Seine towards Notre-Dame and the Île de la Cité, taking in the cathedral's exterior and the riverside atmosphere without needing to queue for any single attraction.
- Continue on foot or by metro towards the Eiffel Tower if time allows, viewing it from the Trocadéro gardens rather than queuing for a ticket up, which eats hours you don't have.
- Head back with a solid buffer — CDG's security and immigration lines can be slow at peak times, so aim to be back at the airport at least 2 hours before your return leg, given the airport's size and the RER's occasional delays.
If your layover is shorter, simply riding the RER B into central Paris for a walk near Notre-Dame and straight back is enough to say you've seen something of the city without cutting things fine.
Practical notes
- A Navigo Easy card or a paper carnet of tickets both work for the RER and metro — see our Paris Metro tickets and passes guide for the details.
- Keep valuables close — pickpocketing is a genuine, well-documented issue on the RER B and around major tourist sights, more so than on most of Paris's ordinary metro lines.
- Left-luggage facilities exist at both CDG and Orly if you're not travelling with just hand luggage.

Frequently asked questions
Do I need a visa to leave a Paris airport on a layover?
If you're entering the Schengen area for the first time on this trip, many nationalities get visa-free entry for short stays, which covers most transit visits, but it counts against your 90-day Schengen allowance. Confirm the current rule for your specific passport before you travel.
Which Paris airport is easier for a layover, CDG or Orly?
CDG, thanks to the direct RER B train into central Paris. Orly requires an extra connection, so budget more time if you're routed through there.
How do I get from CDG to central Paris?
The RER B train runs directly from the airport to central Paris in around 35–50 minutes. A taxi is an option too, but is more exposed to traffic delays.
Is Paris worth leaving the airport for on a short layover?
With 7–8 hours or more via CDG, yes — a focused walk along the Seine or towards the Eiffel Tower is genuinely workable. Under about 5 hours, or via Orly, the margin gets tight.
