Paris public transport can seem complex at first, but a few simple basics make the city much easier to navigate. This TLC Paris guide gives an easy overview of the métro, RER and some of the most practical routes before opening a transport app.
PARIS TRANSPORT NOTES
The Paris métro mainly covers central Paris, while RER trains connect longer distances including airports, Disneyland Paris and
Versailles. Métro lines are numbered, and in differrent colours, and identified by their final station.
Paris buses can be simpler than the métro for short distances and sightseeing. Several routes pass major landmarks while allowing you to stay above ground and see the city. For ex. Nr 95/39 takes you easily from
Opera,
Louvre etc through the Left Bank to
Montparnasse.
Most central Paris journeys use standard tickets or Navigo passes. Airport routes and destinations outside central Paris often require separate tickets.
TLC Tip
Keep your ticket or phone pass until the end of the journey. Some stations require scanning again when changing lines or exiting.

Métro vs RER

Line Numbers & Colours
Paris métro lines are numbered and shown in different colours. First check the line number, then check the final station to choose the correct direction.
End Stations
Directions are shown by the final station. If the app says “Line 1 direction La Défense,” follow signs for La Défense even if you leave before the final stop.
Transfers
Changing lines can involve long corridors, stairs and several signs. Leave extra time at large stations such as Châtelet–Les Halles, République, Montparnasse or Gare du Nord.
Ticket Basics
Central Paris journeys and airport journeys can require different tickets. Buy the correct fare before boarding and keep the ticket or phone pass until the end.
Useful Apps
Bonjour RATP, Île-de-France Mobilités and Google Maps can help with live routes. Use apps for exact timing, but understand line numbers and final stations before boarding.
Common Mistakes
Common mistakes include taking the right line in the wrong direction, missing RER branch changes, buying the wrong ticket or leaving the ticket behind before exiting.
Stairs & Luggage
Many Paris métro stations have long stairways and limited elevator access. With heavy luggage, strollers or mobility concerns, taxis or direct transfers can sometimes be easier.
Line maps, routes, colours, schedules, ticket systems & prices may change over time. Always confirm final details before travelling.
