Getting around Paris: Navigo, zones and the périphérique
Transport · 7 min read · Reviewed
Paris has the densest urban rail network in Europe and a fare system to match. Understanding it properly is worth real money, because the biggest single decision — whether to live inside the boundary or outside it — turns almost entirely on how the network treats the crossing.
Two changes matter more than anything else. In 2015 the Navigo season pass went flat-fare across every zone, which removed the financial penalty for living further out. And the Grand Paris Express and the métro extensions are steadily connecting the inner suburbs to each other rather than only to the centre.
Together they mean the commuter calculation here looks nothing like it did a decade ago, and nothing like a British one.
The network, in four layers
The métro is the dense inner layer: sixteen lines, stops every five hundred metres or so, and inside the boundary you are almost never more than a short walk from one. It is slow over distance and unbeatable over two miles.
The RER is the fast layer — five lines running underneath central Paris and out into the suburbs with far wider stop spacing. An RER trip from the inner suburbs to the centre is often quicker than a métro trip across Paris, which is the fact that makes Vincennes, Boulogne and their equivalents work.
Trams run mostly around the outside, including the T3 orbital along the boundary, and the Transilien network covers the wider Île-de-France. Above all of it sits a bus network that is genuinely useful outside the peaks and genuinely slow inside them.
Navigo is flat-fare, and that redraws the map
A monthly or annual Navigo pass costs the same whether you travel within Paris or from the outer edge of Île-de-France. There is no zonal ladder to climb, so unlike London or the South East, moving further out does not raise your travel cost at all.
The consequence is that outer living is priced in time rather than money, which is a far more forgiving trade for anyone whose journey is genuinely fast. The suburbs sitting on a métro extension are the obvious winners, and Montreuil, Pantin and Saint-Ouen have all repriced accordingly.
Employers are legally required to reimburse at least half the cost of a season ticket used for commuting, which puts the effective price of unlimited regional travel low enough that owning a car in Paris is very hard to justify.
There is no zone premium on a Navigo season ticket. Living twenty kilometres out costs the same in fares as living in the Marais, so the whole trade is journey time — which is why the commute figures on this site matter more here than the map does.
The périphérique is a road, not a wall
Rents inside the boundary and rents immediately outside it differ by considerably more than the transport difference justifies, and the métro crosses the ring in a dozen places. That gap is the most exploitable fact in the Paris market.
Line 11 out to Rosny, line 12 to Aubervilliers, line 14 north to Saint-Denis and south towards Orly, line 4 to Bagneux: each extension has pulled a commune into the effective city. The pattern to look for is a place where a terminus opened recently and rents have not fully caught up.
The counterpart is that the crossing is not uniform. A commune ten minutes' walk from a métro station is a different proposition from one on top of it, and a bus at each end turns a nominally short trip into a long one.
Cycling, and the thing that changed fastest
Paris has built protected cycle lanes at a pace few European cities have matched, and the rue de Rivoli axis and the north-south routes are now genuinely usable. Cycling has gone from a minority activity to a mainstream commute in about six years.
Vélib' is the docked hire scheme, cheap on a subscription and useful precisely because you can ride one way and take the métro back. It is the standard answer to a journey the rail network handles badly.
Car ownership has been made steadily harder on purpose: parking is expensive and scarce, low-emission rules keep tightening, and several central axes are closed to through traffic. If your plan involves a car in Paris, price the parking before you price the flat.
Common questions
Does it cost more to commute from the suburbs in Paris?
Not in fares. The Navigo season pass has been flat-fare across every zone since 2015, so a journey from the outer edge of Île-de-France costs exactly what a journey within Paris costs. The cost of living further out is journey time, and your employer must reimburse at least half the pass either way.
Is it worth living just outside the périphérique?
Very often, yes. Rents drop sharply at the boundary while the métro crosses it in a dozen places, so a commune on a recent line extension can put you fifteen minutes from the centre at a materially lower rent. Check the walk to the station rather than the name of the commune.
Do I need a car in Paris?
No, and the city has spent a decade making sure of it. Parking is scarce and expensive, low-emission rules keep tightening, and the rail network reaches almost everything. A car makes sense only for regular travel outside the region, and even then hiring usually beats owning.
