Paris Public Transport Guide: Metro, RER, Buses & Tickets

Paris offers one of the world’s most efficient public transportation networks, making it easy to explore iconic landmarks without a car. With options like the metro, RER trains, buses, trams, bikes, and more, visitors can move quickly and affordably across the city and suburbs.

Overview of Paris’s Transport Network

The integrated system covers central Paris and the Île-de-France region, using simplified 2025 ticketing for seamless travel. Key components include 16 metro lines with over 300 stations, five RER lines for faster regional trips, extensive bus and tram routes, and bike-sharing programs. Public transport operates daily from around 5:30 AM to 1:30 AM, with higher frequency during peak hours.

• Metro: Fast underground service with color-coded lines.
• RER: Express trains linking city center to suburbs and airports.
• Buses and Trams: Surface options for scenic views and outer areas.
• Bikes and Scooters: Eco-friendly rentals for short distances.

Mastering the Metro System

The Paris metro is the backbone of urban travel, featuring 16 lines and more than 300 stations recognizable by yellow ‘M’ signs. Trains run every 2-5 minutes during the day, extending service until 1:45 AM on weekends. Lines are numbered and color-coded, with directions indicated by terminal stations on platforms and maps.

Avoid rush hours (7:30-9:30 AM and 5-7:30 PM) on busy lines like 1, 4, and 13 to dodge crowds. Stations offer maps, ticket machines, and staff at service points for assistance.

RER: Fast Regional Connections

The RER network comprises five lines (A-E), each color-coded, serving Paris and suburbs from 6 AM to 1 AM. These trains travel faster than the metro with fewer stops, ideal for cross-city journeys like Champs-Élysées to Gare de Lyon on RER A. Within Paris, metro tickets suffice; beyond requires zone-specific passes.

Hold tickets until exiting, as gates require validation. Major hubs include Châtelet-Les-Halles, Gare du Nord, and Gare de Lyon.

Buses and Trams for Scenic Rides

Buses provide above-ground views of landmarks, operating from early morning to evening with 10-60 minute intervals. Trams serve peripheral areas outside central metro coverage, using the same tickets as buses for 90-minute transfers. Night buses (Noctilien) run post-metro hours.

• Best Sightseeing Routes: Bus 69 (Marais to Eiffel Tower), Bus 72 (Saint-Germain to Louvre).
• Tram Tips: Useful for La Défense (T2) or Versailles outskirts.

2025 Ticketing Simplified

Recent updates replaced the old t+ multi-zone system with two main tickets (airports excluded): Bus-Tram at €2.05 (90-min transfers) and Metro-Train-RER at €2.55 (2-hour transfers). Passes like Navigo Easy (reloadable card) or Mobilis day passes offer unlimited travel. Buy at machines, apps, or stations; same tickets work across metro, buses, trams, and RER within Paris.

Airport Transfers Made Easy

From Charles de Gaulle (CDG): RER B reaches central Paris (Gare du Nord) in 30 minutes for €10.30; hold ticket to exit. Orly Airport: Line 14 + OrlyVal (30-40 min, €10.50) or OrlyBus to Denfert-Rochereau (20-25 min).

• CDG Tips: RoissyBus direct to Opéra (€16.60, 60 min).
• Orly Options: Tram T7 to Villejuif then metro.

Bike Sharing and Active Travel

Vélib’ Métropole offers thousands of bikes (classic and electric) at 1,400+ stations. Unlock via app for €1.70/30 min (classic) or €3/20 min (electric). Great for short trips along Seine or parks. Electric scooters (Lime, Dott) provide fun alternatives; helmets recommended.

Walking suits central areas: stroll from Notre-Dame to Eiffel Tower (1-2 hours) or use Vélib’ for hybrid journeys.

Taxis, Rideshares, and Driving

Taxis/Uber suit luggage-heavy trips or late nights; fares start €4 + €1.20/km. Official taxis have yellow lights. Driving discouraged due to traffic, parking scarcity, and ZTL zones—use public options instead.

Accessibility and Practical Tips

Many stations feature elevators, though not all; check RATP app for accessible routes. English signage and Google Maps integration aid navigation. Download Citymapper or Bonjour RATP for real-time updates.

• Validate tickets on first use.
• Pickpocketing common—keep bags secure.
• Staff wear blue jackets for help.
