How to buy a ticket

To purchase tickets, a Navigo pass is required. The Navigo Easy card (the most standard pass) can be purchased for €2 at train stations, or free of charge via the Île-de-France Mobilités app. Please note that major stations and airports can be crowded, which may result in longer waiting times.
