Paris subway tips
A Powerful Network
Parisians are proud of their subway system. With more than a century of history, the system is vast, effective, and well-managed. If you can imagine that 6 million passengers are transported by the subway system every day, you can understand what a powerful network it is. It is said that from any location in downtown Paris there is a subway station not farther than 500 meters from you.
Traveling like Parisian
Using the subway as a means of transit is the Parisian way of life. When discussing a location, Parisians always mention the name of the nearest METRO station. If you are invited by a company to visit their office, you shouldn't be surprised if they do not arrange to pick you up from your hotel, but instead give you directions from the subway. The subway is more convenient, and avoids traffic jams. It is the easiest way around, even if you are new to Paris.
Two Systems
What we have been referring to as the "subway" is, in fact, two systems in one. The Metro (short for Metropolitan) has 14 lines (numbered 1 through 14), and runs in downtown Paris. The RER (Reseaux Express Regionale - read as Regional Express Networks) has 5 lines (lettered A through E), and runs through both downtown and the suburbs.
Tickets
There are several ticketing options available for those using public transit: individual tickets, the "Paris Visite" pass, the "Carte Orange" pass, or the "Mobilis" pass. Each of these is described in some detail below. Of all these kinds of tickets, you will be interested in Carte Orange and Mobilis most likely.
Individual tickets for the downtown area are valid within zones 1 and 2. Each can be used for a single trip on the Metro, RER, bus, or tram. The price is 1.50 euros for one ticket or 11.10 for 10 tickets (called a Carnet). Children from 4 to 11 years old can have half price discount for a Carnet, say 5.50 euros for 10 children tickets.
Individual tickets to Paris suburbs are priced based on the distance traveled. For example, from downtown Paris to the GIS hotel Paris (station NEUILLY PLAISANCE, Zone 3) is 2.8 euros one way, 22.4 euros for 10 tickets; from the GIS hotel Paris to Disneyland Paris is 4 euros one way; from Charles de Gaulle airport to downtown Paris is 10.05 euros one way, to GIS hotel Paris is the same.
The Mobilis is a one-day ticket that allows unlimited travel on the Metro, RER, bus, RATP, ADATRIF, APTR, and SNCF suburban network. It excludes the Orlybus, Orlyval, Roissybus, Roissyrail and Orlyrail. Price is based on area of coverage, for Zone 1 - 3, it is 7.50 euros.
