Your guide to public transport in Paris and the Ile de France region

The concept

In a single app – and in just a few clicks – find all the information you’ll need to get around Paris and the Ile-de-France region:

  • Find the times, in real time, of the next RER, metro, bus, Noctilien night bus, tramway and the airport lines.
  • Use our geolocation feature to display all of the transport facilities available, including Velib and Autolib stations, and the availability of bikes and cars.
  • Find the best itineraries to your destination, directly from our home page.
  • Receive customised alerts in case service is disrupted on one of the lines you use regularly.
  • Display line maps in landscape mode for the RATP RER (A and B), metro, bus, Noctilien night bus, RATP tramway and airport lines (Roissybus, Orlybus and Orlyval).
  • Things to do in the vicinity.
