Tips (You will find maps, time tables, etc., about metro and RER here.
Please do not mistake the RER B station « Orsay-Ville » for the Paris metro station « Musée d’Orsay ». From Paris, you must buy a ticket specifically for « Orsay-Ville ». A Paris metro ticket is not sufficient !.
There is a special ticket called « ParisVisite » .
It comes as a card with a coupon attached and opens the doors to the whole Ile-de-France network : Metro, RER, Buses, Trams, SNCF overland suburban trains. How about a few destinations ? – Disneyland Resort Paris (zone 5), the Château de Versailles (zone 4), Orsay-Ville (zone 5) or the airports at Charles de Gaulle (zone 5) and Orly (zone 4). The pass becomes valid from the first day of use (and not when you buy it). Once you have bought your ParisVisite pass, fill in the card with your name and first name. Take care to write the serial number of the card on the coupon and add your planned start date. The card and coupon must be kept together and produced for inspection when requested. The price for Five days (Zones 1-5) is 70.30 €.
