What is the Mobilis single-day pass?
Let’s say you stay in Paris only for a day, and intend to see the city rather than just go to Le Louvre museum. It’s likely you will walk and take the metro and buses several times. Rather than buying a ticket for every metro ride, buy the Mobilis ticket. You pay once, and you can access the metro and take any bus line as many times as you wish during the day. The ticket lasts the whole day, from the first metro train to the last one. You can also use the single-day pass to take the RER (regional express railway) and even trains at the railway stations, as long as you stay within the number of “zones” of your pass. “Zones” are concentric circles of varying diameters which determine the price of the fare. Paris is “zone 1” for instance. The immediate outskirts are “Zone 2 and 3”. The larger the circle, the farther from Paris you travel, the higher the fare.
