With the Noctilien night buses, you never need to stop moving. This service lets you get around at times when other public transport lines have stopped running. Every night between 12:30 AM and 5:30 AM, travel around Paris and the region using the 47 lines that serve Paris and more than 200 other towns.

Several carriers, one network

Many means of transportation and interconnected lines make the Île-de-France network your key to travel across the entire Paris area.  On a day-to-day basis it is overseen by Île-de-France Mobilités (IDFM), and operated by three carriers: SNCF Transilien, RATP and OPTILE.

Île-de-France Mobilités (IDFM) is the organising authority for public transportation in Paris and the surrounding area. It covers the Île-de-France region, the city of Paris, and 7 other departments in the region, and is in charge of:

  • designing, organising, and financing the entire public transportation network for Île-de-France (trains, RER regional trains, underground, trams, T Zen and buses),
  • bringing every stakeholder together (elected officials, equipment manufacturers, carriers, infrastructure managers, etc.) to improve the services we bring to passengers,
  • commissioning and managing transportation modernisation projects, which are run by SNCF Transilien, RATP and OPTILE.

Transilien and RATP work together to make sure the network in Paris and the region runs smoothly. They are responsible for:

  • on-time operations for the lines they operate,
  • safety of passengers and employees,
  • quality of service for passengers (customer service, information, cleanliness),
  • modernisation and development of the public transport network. The two carriers share management of the various means of transport and network lines, and they jointly operate certain RER lines (A and B) and the Noctilien night bus.

With different fare zones for Paris and the surrounding area, you pay only for the distance you travel. There are 5 zones, and fares for these passes are based on how many zones you would like to travel to:

Finding your way in a station

When you are in a metro or RER station, you can use the signs to find what you are looking for.

To ask an employee a question about an itinerary or about purchasing a ticket, for example, you can go to an information desk. You can find them by following the directions indicated on station signs.

It's easy to find the line you want using numbers and/or colour codes (metro), or letters (RER) and/or endpoints. Once you've identified your line, follow the arrows that show the way. Make sure you're taking the line in the right direction, by checking its endpoint and the station you'll be stopping at.

To leave a station, follow the signs that say "Sortie" ("Exit"). Walk through the exit door, which may open automatically or manually.

Elevators & escalators Station signs will inform you about the stairs, escalators, and elevators you can use to get around.

  • On Saturdays, Sundays, and holidays, all day long,
  • From Monday to Friday before 6:30 AM, from 9:30 AM to 4:30 PM, and after 7:30 PM.
