June looks calm on the calendar, but it's actually two things at once: an unusually transport-friendly night on 21 June and the quiet start of French strike season. Knowing the difference means you leave nothing to chance.

Fête de la Musique: what changes on 21 June?
RATP runs a special service on the night of 21 June. Six metro lines — 1, 2, 4, 6, 9, and 14 — operate all night until the first regular morning service. Service is concentrated around major interchange stations: Châtelet, Gare du Nord, Trocadéro, and Gare de Lyon. Smaller stations on these lines may be closed.
The busiest chokepoints are Châtelet-Les Halles (lines 1, 4, 14) and République (lines 3, 5, 8, 9, 11) — both are major concert spillover zones. If you're heading home between midnight and 02:00, board at an outer station rather than fighting the crowd at a central one. Line 14 is fully automated and runs most reliably under load.

Note: Magnetic paper tickets are no longer accepted from June 2026. You need a Navigo Easy card (€2,00 to buy, reloadable, no photo required) or the Bonjour RATP smartphone app. Both the Navigo Easy card and single tickets can be added to Apple Wallet or Google Wallet through the Bonjour RATP app, enabling tap‑and‑go with your phone.
Strike season: how to prepare before July
Four concrete steps before your trip:
- Install the Bonjour RATP app and enable service notifications. French law requires RATP to give 48 hours' notice before any strike. The app is the fastest channel for that warning — earlier than news sites. (iOS / Android)
- Load a buffer of t+ tickets on your Navigo Easy card. If a strike runs for a day, single tickets on a working bus or RER line keep you moving. Buying tickets during a disruption at a crowded station is avoidable stress.
- Know your non-RATP alternatives. Vélib' (bike share) and taxis/VTC operate independently from RATP. Regular Île-de-France Bus lines often run reduced — not zero — service during strikes.
- Check ratp.fr/infos-trafic before you travel. Any active strike notice (préavis de grève) is listed there. Check two days before your journey, not on the morning of.
Getting from CDG Airport in June
Take RER B directly to central Paris. From CDG Terminal 2, the journey to Châtelet-Les Halles takes around 35–40 minutes on a direct service. Trains run every 10–15 minutes during the day.
The correct ticket is the Ticket Paris Région ↔ Aéroports — €14,00 single (child 4–9: €7,00; under 4: free). This replaces the old zone-based CDG ticket as of January 2026. If you already hold a Navigo weekly or monthly pass covering all zones (1–5), it is valid on RER B to CDG with no extra charge.
You can load the airport ticket onto a Navigo Easy card — no separate paper ticket needed. Your standard €2,55 single tickets are not valid for this route.
If RER B is disrupted or you are on a budget, use the bus line 9517 (which replaced the discontinued RoissyBus in early 2026). It runs via Saint-Denis Pleyel to CDG in around 30 minutes for just €2,55 (standard single fare, free with a Navigo pass)—making it the fastest and cheapest road transfer.
Common mistakes
Mistake: Assuming French strikes only happen in winter. Fix: The transport strike season in France runs from June through September, often tied to summer contract negotiations. RATP is legally required to give 48 hours' notice — set your Bonjour RATP app notifications now, not when you're stranded.
Mistake: Planning to take the metro to a busy central station late on 21 June with no backup. Fix: Châtelet, République, and Bastille become the biggest concert spillover points after midnight. Board from a less central station on line 1 or 14, or walk one extra stop and board there instead.
Mistake: Buying RER B tickets one at a time at CDG airport on arrival. Fix: Load the Ticket Paris Région ↔ Aéroports (€14,00) onto a Navigo Easy card before you fly — or at any Paris metro station on a previous day. Machine queues at CDG in June are long.
