Why Take the RER B Train?

The RER B (Réseau Express Régional Line B) is the commuter train that links Charles de Gaulle Airport directly with the heart of Paris. It is commonly regarded as the most convenient and economical option, as:

  • Direct Access: You can reach most central destinations without the need to transfer lines.
  • Fast Travel: Journey time to Gare du Nord, one of Paris’s principal train stations, is roughly 30–40 minutes.
  • Budget-friendly: A one-way fare is roughly €11.45 (2025 prices), far cheaper than a taxi.
  • Regular Service: Trains depart every 10–15 minutes from morning until evening.

Step-by-Step: How to Take the RER B from CDG

While many visitors find airports bewildering, getting to the train is far simpler than it seems. This is the most straightforward way:

  1. Follow Signs for “Paris by Train / RER B”: Once you’ve gathered your bags, watch for the signs that read “Paris par train” or “RER B Paris”. They are generally located close to Exits (Sorties) 11 and 12.
  2. Walk Along the Arrow Signs: Blue and white arrows at the airport clearly lead the way to the train station. Just follow the arrows.
  3. Head Down to the Train Station: Each terminal—Terminal 2 and Terminal 3—offers direct access to the RER B station. If you’re located in Terminal 1, you can take the complimentary CDGVAL shuttle train to Terminal 3, where the RER station is located.
  4. Buy Your Ticket:  You can obtain a ticket from the self-service machines or from the staffed counters inside the station. Hold on to that ticket—you’ll need it to get through the gates in Paris.
  5. Board the Train: After you reach the platform, locate the trains destined for Paris Gare du Nord. Simply board—no reservations necessary.
