How to search and find a route in Paris subway

Getting from one point to another in Paris by underground (metro in french !) has never been so easy! This site makes it possible to quickly find the best underground route in Paris and the suburbs of Paris using the RATP or SNCF network (lines 1 to 14 of the metro, line A, B, C and D of the RER). You only need to know your departure station and your destination station, and the application calculates automatically and in a fraction of a second the fastest route by metro or RER, avoiding, if possible, connections and / or walking.

The RATP is a public establishment founded in 1948 and managing a large part of public transport in Paris (including the bus and subway) and its suburbs. The SNCF (National Society of French Railways) was created in 1937 and manages part of passenger transport in Ile-de-France, including some sections of RER.


You can travel from one end to the other of the subway lines 1 to 14 with or without a connection using a single, single-rate Zone 2 ticket. On the other hand, the rate varies with the distance if one takes the lines of RER outside zones 1 and 2.
Examples of tariffs applied by the RATP:With the Airport ticket, the cost of a trip between a RER B station and Charles-de-Gaulle airport is 10.30 euros. Example: Châtelet-les-Halles to CDG Airport 1.

The cost of a Ticket t + RATP sold per book of 10 is 1.69 euros (16.90 euros the book). Purchased individually, the t + ticket costs € 1.90. The t + ticket allows you to travel on all subway lines regardless of the zone, and in the RER in zones 1 and 2.
Examples of trips possible with a simple ticket t + : North train station to Gare de Lyon, Châtelet les Halles to Gare du nord.

With a single ticket t +, you can travel for two hours from the first validation of the ticket, the trip may include one or more metro / metro or metro / RER connections. If your RER trip leaves Paris, you must buy a ticket corresponding to the desired destination, whose price depends on this destination.

The number of passengers using metro lines is 5.3 million per day, or about 1.5 billion passengers a year. Some lines are much more crowded than the others, like the lines 1 (which runs Paris from east to west) and 4 (which travels Paris from north to south). Overall, attendance has been rising for several years.

The ten most popular metro stations are : Gare du Nord, Saint-Lazare, Gare de Lyon, Montparnasse-Bienvenüe, Châtelet - Les Halles, Gare de l'Est, République, Les Halles, Bastille, Châtelet, Hôtel de Ville.

The Paris Metro, operated by the RATP, comprises 16 lines numbered from 1 to 14, including lines 3bis and 7bis, whose total length is approximately 220 km. To this must be added the RER lines A and B, also largely managed by RATP. The other RER lines are managed by SNCF.

The first line of the Paris metro, which connected the Porte de Vincennes to the Porte Maillot, was inaugurated shortly after the opening of the 1900 World's Fairs. The network then densified very quickly until the Second World War. The metropolitan network of Paris has the particularity of being very dense, with a fairly small distance between two successive stations. It is in fact the most dense metro network in the world, each point of Paris intramural being located less than one kilometer from a station. There are in fact about 300 metro stations for a total area of ​​105 square kilometers (intramural city), or almost three stations per square kilometer.

This makes multiple possibilities of journeys, more or less fast or practical. If the subway trains have a maximum of six cars, those of RER can be much longer. Most intramural lines are underground. Only lines 2, 5 and 6 have air sections inside Paris. The longest line is line 8, which runs a little over 23 km between each terminus. The shortest line of the network is line 3bis, which has only four stations for a length of 1.3 kilometers.

Frequency of passage:

At peak times, the frequency between each subway train is approximately two minutes and four minutes during off-peak hours. In the evening, this frequency between two trains can be eight minutes. The frequencies of passage of the RER are lower: of the order of eight minutes in Paris intramural rush hour for the RER A for example.
