RER B Train from Paris to CDG Airport: Times, Tickets & Tips

The RER B train is the fastest and easiest way to get from central Paris to Charles de Gaulle Airport (CDG), with direct trains every 10–15 minutes and a travel time of around 30 minutes.

The suburban train line RER B is usually the best public transportation between downtown Paris and Charles de Gaulle Airport (CDG). Getting to the airport from Paris by RER B train is relatively cheap and fast. In central Paris, RER Ligne B trains stop, amongst others, at Saint-Michel-Notre-Dame, Châtelet-Les Halles, and Gare du Nord en route to Aéroport Charles de Gaulle 2-TGV Station.

For most travelers, the RER B is the best option unless traveling late at night or with heavy luggage, when private transfers are certainly a more pleasant choice. Due to the train airport surcharge, it may even be cheaper for small groups and families.

→ A faster CDG Express train is due to open by mid-2027 to directly connect the airport with Gare de l’Est (and Gare du Nord). RER B might remain a better choice.
