The transport network of Paris and its region is renowned for being one of the best in the world. With the metro, the RER, buses and trams, getting around Paris is child's play!
Tickets are sold individually or in a set of 10, and are valid for one journey with transfers, except for buses. There are special offers suited for tourists such as the Paris Visite card, which gives you unlimited travel on the Paris network for up to five consecutive days.
With 15 lines and more than 300 stations, the Parisian metro lets you go all over the city from 5:30 AM (starting out of the first metro) until 1:15 AM from Sunday to Thursday (arrival of the last metro at its destination). On Fridays, Saturdays and the day before holidays, the metro runs until 2:15 AM.
The 5 RER lines allow you to travel through Paris quickly and to venture beyond into the Ile-de-France. Line B serves Paris' two main airports, Roissy-Charles de Gaulle and Orly. Line A goes to the La Défense business district and to Eurodisney. The RER C will take you to the Château de Versailles.
The bus lines, which began in 1906, offer dense coverage of Paris and the suburbs and are an excellent way to discover the city. The Noctilien network runs all night.
The renaissance of the tram system began in the 1990's, first in the suburbs, then in Paris. There are now three tram lines. They are fast, reliable, and above all environmentally friendly. A line is being built and extended around the border of Paris to allow for rapid travel from one Porte to another. The extension of the T3 tram from the Porte d'Ivry to the Porte de la Chapelle, in the eastern part of Paris, should be in service by the end of 2012.
You can buy tickets at metro and RER stations, some bus stations and local stores: bookstores, newsagents, tobacconists, etc
