Is the Metro safe at night?

Generally, yes. Stay alert in crowded areas to prevent pickpocketing, especially on lines 1, 4, and 9.

Do I need to tap out when I leave?

No. You only tap to enter. You must keep your ticket until you leave the platform, however, in case of an inspection.

Are the doors automatic?

On many older trains, you must push a button or lift a lever to open the doors when the train stops. If you don't do it, the doors won't open.

Navigating the Paris Metro like a local

Use the Citymapper or Île-de-France Mobilités app for real-time routing, and buy a Navigo Easy pass at any station kiosk to load tickets. Always keep your validated ticket until you exit the station, as ticket inspectors frequently check for proof of travel.

Get a Navigo Easy pass. Skip the paper tickets that demagnetize. Go to a yellow vending machine at any station, select 'Buy Navigo Easy' (€2), and load a 'carnet' (pack of 10 rides) for approximately €17.35.
Master the line numbers and directions. Metro lines are numbered 1–14. To find your direction, look for the 'terminus' station—the name of the very last stop at the end of that specific line in the direction you are traveling.
Navigate transfers (Correspondance). Follow the pink signs labeled 'Correspondance' to switch lines. Be prepared to walk; some transfers, like Châtelet or Montparnasse, can involve up to 10 minutes of walking through tunnels.
Know the gate etiquette. Tap your pass on the purple reader. Walk through the gate and keep moving; do not stop immediately, as people behind you will be walking briskly.
