The Paris metropolitan transit system, also known by its initials RATP (for Régie Autonome des Transports Parisiens) operates the underground trains and nearly 300 stations of the renowned Métro (short for Métropolitain), as well as hundreds of city buses, trams, funiculars, and smaller services.

Bonjour RATP App

RATP offers a highly useful smartphone app, Bonjour RATP, for free, for Apple iOS and Google Android devices. The app can plan your route, tell you where to stand on the platform for optimal transfers between trains, and even which exit to use when leaving your destination station (this is very useful! You'll see!) If there's a delay on your route, it will offer alternatives.

You can buy transit tickets and passes on the app and use your phone as your ticket. We strongly recommend that you download Bonjour RATP before arriving in Paris, set up an account, and be ready to ride when you arrive. More...

You should also consider the RATP city buses, as they can be more convenient than the Métro from some locations and on some routes.

Here's all you need to know about buying and using tickets and transit passes.

RATP services include funiculars, cablecars on rails that ascend and descend steep slopes, such as the Funiculaire du Montmartre which slides up and down the slope of Montmartre from near Pigalle to near the Basilique du Sacré-Coeur and Place du Tertre (map).

Île-de-France Mobilités App

Île-de-France Mobilités is the organization that coordinates all transport in the Paris region: Métro, RER trains, trams, funiculars, etc. If you plan to travel more extenively in the Paris region (Île-de-France), you may want this app as well.
