Getting Around Paris: Metro, RER and Public Transport Explained Step by Step
Getting around Paris by public transport is the most efficient way to see the city, but the system can seem daunting at first glance. A metro network with 16 lines, suburban trains that cut across the city, buses and trams covering what the metro doesn’t reach: everything works as an integrated network, but it has its own rules. This guide explains how each mode of transport works, which travel pass to buy depending on how long you’re staying, and how to get from the main airports into the centre without any complications.
The Paris Metro — The Backbone of Urban Transport
The Paris metro has 16 lines, each identified by number and colour, and covers almost every part of the city within the Peripherique. During peak hours, trains run every 2-5 minutes; in off-peak periods, the gap can stretch to 8-10 minutes. Service closes at around 1:00 am on Monday to Thursday and Sunday nights, and runs until 2:15 am on Fridays and Saturdays.
When reading the map, the most practical approach is to learn the lines by the name of the terminus (the final destination of the train in each direction) rather than the line number. On the platform, signs always show the terminus name and the intermediate stops.
The most useful lines for visitors are Line 1 (east-west axis through the main landmarks: Louvre, Champs-Elysees, La Defense), Line 4 (Gare du Nord, Chatelet, Montparnasse), Line 6 (viaduct views: Eiffel Tower, Trocadero) and Line 14 (fast and fully automated, connecting the centre with Gare de Lyon and Orly airport since 2024).
The RER — When to Use It and When to Avoid It
The RER is a suburban rail network that works differently from the metro: it crosses the city without stopping at every neighbourhood, making it faster for longer journeys but less useful for short trips within the city. There are five lines (A, B, C, D, E) and it shares some stations with the metro, although with separate entrances and separate validation.
The RER fare system is divided into zones: Zone 1 covers central Paris and costs the same as the metro. When travelling outside the city towards the suburbs (Zones 2 to 5), the price increases depending on the destination. This matters: if you use a metro ticket to enter the RER but your destination is outside Zone 1, you need a specific ticket for that journey.
When to use the RER: Charles de Gaulle Airport (RER B), Versailles (RER C), Disneyland Paris (RER A), Gare du Nord and Chatelet for direct connections. When not to use it: for moving around central Paris, the metro is more straightforward and avoids the need to manage fare zones.
Buses and Trams in Paris
Buses have a poor reputation among visitors because they seem slower, but they offer something the metro cannot: you see the city. For tourist routes or areas with limited metro coverage, the bus is a good option. Line 69 in particular, which crosses the historic heart of Paris from the Champ de Mars to Pere Lachaise, is widely considered one of the most scenic routes in the city — a free sightseeing trip in disguise.
The tram mainly operates on the outskirts of the city, following the route of the old Peripherique. It is useful for moving between outer neighbourhoods but offers little practical value for most visitor itineraries. The same travel pass is valid for metro, RER Zone 1, bus and tram.
Travel Passes — Which One to Buy for Your Stay
This is the point that causes the most confusion. From 2024, the old paper magnetic tickets have been progressively replaced by the rechargeable Navigo Easy card or by smartphone NFC payment. The individual t+ ticket is no longer sold on paper; it is loaded digitally. Here is a summary by length of stay:
| Pass | Best for | Approx. price | Coverage |
| Single ticket t+ | 1-2 occasional journeys | ~€2.15/trip | Metro + bus Zone 1 |
| Navigo Easy (10 trips) | Short stays, irregular use | ~€17.35 | Metro + bus Zone 1 |
| Navigo Jour (day pass) | 1 intensive sightseeing day | ~€8.65 | Zones 1-5 unlimited |
| Paris Visite 2 days | Weekend break | ~€19.61 | Zones 1-3 unlimited |
| Paris Visite 5 days | Full week or longer | ~€38.35 | Zones 1-3 unlimited |
| Navigo Semaine (week) | Full Mon-Sun week | ~€30 | Zones 1-5 unlimited |
Note: Prices are approximate. Verify before publishing at ratp.fr or at station ticket machines.
Recommendation by profile: for a 1-2 day stay with lots of journeys, the Navigo Jour or Paris Visite are the most convenient. For a full week, the Navigo Semaine is the most economical option if transport is used every day. For stays with very occasional use, the 10-trip Navigo Easy is sufficient.
How to Get from Paris Airports to the City Centre
Paris has three airports with city connections. Here are the most practical options for each:
Charles de Gaulle (CDG): the most widely used. The fastest and most economical option is the RER B, with trains every 10-15 minutes and a journey of around 35 minutes to the central stations (Chatelet-Les Halles, Saint-Michel, Luxembourg). Price: approx. €11-12. The Roissybus connects CDG with the Opera in around 60 minutes. Taxis have an official fixed fare: €56 to the Right Bank, €65 to the Left Bank.
Orly: Paris’s second airport. The most direct connection is the Orlyval (automated shuttle train) to Antony station, where it connects with the RER B towards the centre. Total journey time: around 35-40 minutes. Price: approx. €12-13. The OrlyBus connects to Denfert-Rochereau station in 30-40 minutes. Since 2024, Metro Line 14 also connects directly to Orly.
Beauvais: used by some low-cost airlines. There is no direct rail connection; a shuttle bus runs to Porte Maillot in Paris, with a journey time of around 85-90 minutes. The service is coordinated with flight arrivals.
Practical Tips for Using Public Transport in Paris
- Always validate your ticket on entry: even if you have boarded the train, validation is mandatory and inspectors carry out random checks with on-the-spot fines.
- Accessibility: the Paris metro has very limited accessibility. Only a few lines (1, 14) have lifts at every station. If you need step-free access, plan your route using the RATP accessibility tool or use the bus network.
- Recommended app: Citymapper is the best app for getting around Paris. It integrates metro, RER, bus, cycling and walking options with live times.
- Peak hours: 8:00-9:30 am and 5:30-7:30 pm. For journeys with luggage or with young children, these windows are best avoided.
- On the bus, validate when boarding: your ticket or Navigo pass must be tapped on the reader next to the driver when you get on, not when you get off.
Frequently Asked Questions About Transport in Paris
What is the best way to get around Paris?
The metro is the most efficient way to get around Paris: it has 16 lines, covers almost the entire city and trains run every 2-5 minutes during peak hours. For longer journeys or getting in from the airport, the RER is the fastest alternative.
Which travel pass should I buy for Paris?
It depends on how long you are staying. For a full week, the Navigo Semaine weekly pass is the most cost-effective option. For short stays of one or two days, the Paris Visite pass offers unlimited travel across all zones. Single tickets only make financial sense for very occasional journeys.
How do I get from Charles de Gaulle airport to central Paris?
The fastest and most affordable option is the RER B, which connects CDG to the city centre in around 35 minutes and costs approximately €11-12. Taxis have an official fixed fare of €56 from CDG to the Right Bank and €65 to the Left Bank.
Do I need to validate my ticket on the Paris metro?
Yes, it is compulsory to validate your ticket or Navigo pass every time you enter the metro or the RER. Failing to validate can result in a fine even if you have a valid pass. On buses, you must also validate when boarding.
Where should I stay in Paris to be well connected by public transport?
The central arrondissements (1st to 11th) offer the best metro coverage. Libere has apartments in Paris that are well positioned for getting around the city by public transport without relying on taxis.
