The Paris métro carries nearly four million passengers every day, whisking travelers beneath the city through 16 lines and more than 300 stations. For first-time visitors, the system might seem intimidating, but it’s actually one of the most logical and efficient ways to explore Paris. Within a few rides, you’ll wonder why you ever considered taxis.
Here’s how to navigate the métro with confidence, avoid rookie mistakes, and move through Paris like you’ve lived here for years.
Understanding the System
The métro consists of 16 numbered lines, each identified by a color and its terminal stations. Line 1, for example, runs east-west from La Défense to Château de Vincennes, passing through major stops like the Louvre, Concorde, and the Champs-Élysées. Line 4 runs north-south from Porte de Clignancourt through Châtelet, Saint-Michel, and down to Montrouge.
You navigate by direction, not by compass points. Signs inside stations show the line number and the name of the final station in that direction. To reach the Eiffel Tower from Châtelet, you’d take Line 4 direction Mairie de Montrouge, change at Odéon to Line 6 direction Charles de Gaulle–Étoile, and exit at Bir-Hakeim. The system uses the word correspondance for transfers between lines.
Trains run from about 5:30 a.m. until just after 1 a.m. on weeknights, and until around 2 a.m. on Friday and Saturday nights. During peak hours, trains arrive every two to three minutes. Late at night, you might wait eight to ten minutes.
Tickets and Passes: What to Buy
Single tickets, called t+ tickets, cost €2.10 and are valid for one journey including transfers between métro lines or from métro to RER within central Paris. You can’t exit the station and re-enter on the same ticket. Buy them in carnets of ten for a discount, or use contactless payment at newer turnstiles.
If you’re staying several days, the Navigo Découverte pass makes more sense. For a one-time €5 card fee, you can load weekly or monthly passes covering unlimited travel in zones 1-5, which includes the airports. The weekly pass runs Monday to Sunday and costs around €30, paying for itself after about 14 single rides. You’ll need a passport photo, available from photo booths in larger stations.
The Paris Visite pass offers unlimited travel for one to five consecutive days, but it’s generally more expensive than buying individual tickets unless you’re making many trips daily. Day passes called Mobilis also exist but are rarely the best value.
Tourists often ask about the Navigo weekly pass mid-week. If you arrive Wednesday and plan to stay through the following Tuesday, you’ll need to buy single tickets or carnets for the first few days, then load a weekly pass starting the following Monday. Do the math based on your actual travel.
Riding Smart: Insider Tips
Keep your ticket until you exit the station completely—you’ll need it to pass through the exit turnstiles, and inspectors regularly check for valid tickets, imposing immediate fines for those without.
At Châtelet-Les Halles, the métro’s largest interchange, follow the clearly marked correspondance signs. The station sprawls across multiple levels, connecting five métro lines and three RER lines. Give yourself extra time here, especially with luggage.
Board through the center doors of the train when possible—they’re less crowded, and you’ll have an easier time exiting. As the doors close, you’ll hear a distinctive two-tone signal. Don’t try to hold them open; another train will arrive in minutes.
The first car and last car are usually less crowded. If you’re riding late at night alone, stay in cars with other passengers and sit near the conductor’s car, marked with a small window at the front or back.
Pickpockets work crowded lines, especially Line 1, which serves major tourist sites. Keep bags zipped and in front of you. The most common tactic involves a crowded doorway during boarding—someone pushes from behind while an accomplice reaches into open bags or pockets.
Station Secrets and Shortcuts
Some stations offer shortcuts between neighborhoods. At Barbès-Rochechouart, the outdoor stretch of Line 2 between Barbès and La Chapelle gives you a glimpse of the elevated tracks that once characterized much of the system. Line 6, which runs elevated between Passy and Nation, offers spectacular views crossing the Seine near the Eiffel Tower.
Free transfers between métro lines must happen within the station—you can’t exit and re-enter. But you can transfer from métro to bus, or bus to bus, within 90 minutes on a single t+ ticket. This doesn’t work from bus to métro, only in the other direction.
During August and parts of July, some lines reduce frequency as Parisians leave for vacation. Weekends year-round can bring maintenance closures on sections of certain lines, with bus shuttles replacing trains. Check the RATP website or look for posted notices.
Exit signs marked sortie lead to street level. Many stations have multiple exits serving different streets—look for the street names listed under each sortie to save yourself a block of walking in the wrong direction above ground.
Beyond the Métro: RER and Buses
The RER (Réseau Express Régional) runs faster trains connecting central Paris with suburbs and airports. RER B serves Charles de Gaulle Airport, while RER C stops near the Eiffel Tower and continues to Versailles. Within Paris, your métro ticket works on RER lines in zones 1-2. Going farther requires a different ticket.
Paris buses use the same t+ tickets as the métro, and they let you see the city above ground. Line 69 between Bastille and the Eiffel Tower passes through the Marais and along the Left Bank—it’s effectively a scenic tour. Board through the front door, validate your ticket, and press the red button to request your stop.
After the métro closes, Noctilien night buses run on reduced schedules. Most routes pass through Châtelet. They’re slower than the métro but invaluable for late evenings.
The métro will take you almost anywhere you need to go in Paris, usually faster than walking and always faster than sitting in traffic. Download the RATP or Citymapper app for real-time directions, but after a day or two, you’ll barely need them. The system has a logic that reveals itself quickly: follow the numbers, watch for correspondance signs, and you’ll navigate Paris like you’ve been doing it for years.
