RATP is the public transportation network in Paris and in Île-de-France. The RATP network includes metro, RER, tram and bus lines. Different offers are available, depending on your needs.
Single-trip tickets (“tickets t+”) are the best option for tourists and occasional users. Everyday commuters can buy a subscription (“pass Navigo”). Some categories of people, such as students, seniors and people in precarious situations, can get discounts. For more information, go to RATP’s website.
