Option 1: RER B + Metro Line 14 Between Charles de Gaulle and Orly Paris Airports
The easiest transfer option between Charles de Gaulle and Orly airports is probably RER B trains (light blue on most maps) and Metro line 14 (purple). All trains departing from the airports stop at the relevant stations.
From Charles de Gaulle (CDG) to Orly (ORY):
- Board any RER B train heading toward Paris and get off at Châtelet–Les Halles.
- Transfer here to Metro Line 14, which now connects directly to Orly Airport.
- Metro station Aéroport d’Orly is inside terminal 3 — it is an easy walk to any of the four Orly terminals.
From Orly (ORY) to Charles de Gaulle (CDG):
- Take Metro Line 14 towards Saint-Denis Pleyel, and transfer to RER B at Châtelet–Les Halles.
- Only board RER B trains with Aéroport Charles de Gaulle as destination.
- Check before travel which Charles de Gaulle Airport station you should use — 1 or 2 TGV. (An error is corrected for free, but it could be very time-consuming — the airport layout is very confusing.)
For some, the walk at Châtelet-Les Halles may be long (almost 500 m / ¼ mile) with luggage. The transfer walk at Antony is very short.
Option 2: RER B + Orlyval Between Charles de Gaulle and Orly Paris Airports
As with Option 1, travel to/from Charles de Gaulle is on RER B trains, but here the transfer is to the Orlyval shuttle service rather than the metro. In contrast to the metro M14 option, not all RER B trains stop at the relevant stations.
From Charles de Gaulle (CDG) to Orly (ORY):
- Take RER B4 trains (final destinations Saint-Rémy-lès-Chevreuse or Massy-Palaiseau) and get off at Antony station.
- At Antony, transfer to the Orlyval light rail for a quick ride to Orly Airport.
- The airport has two Orlyval stations: Terminal 4 and Terminals 1-2-3.
From Orly (ORY) to Charles de Gaulle (CDG):
- Board the Orlyval to Antony.
- At Antony, transfer to RER B3 trains with Aéroport Charles de Gaulle as final destination.
- Check before travel which Charles de Gaulle Airport station you should use — 1 or 2 TGV. (An error is corrected for free but it could be very time-consuming — the airport layout is very confusing.)
The transfer walk at Antony is much shorter than at Châtelet-Les Halles.
Which is the Best Transfer Route Between CDG and ORY?
Both transfer options between Charles de Gaulle and Paris Orly airports take about the same time and cost the same. However:
- If you’re already seated comfortably on a RER B train from CDG, staying on until Antony (for the Orlyval) can be more relaxing than navigating a crowded Metro Line 14 transfer.
- The walk between RER B and Orlyval at Antony is only 50 m, compared to 500 m at Châtelet between RER B and Metro 14. Both transfers are simple, but with luggage, a shorter walk may be easier.
- Metro Line 14 is newer, fully automated, step-free, and fast.
- From Orly Airport, you are likely to have a seat on Metro 14.
Because RER B is heavily used and frequently affected by engineering work, always check routes at RATP or IDF Mobilités before traveling, especially early mornings, late evenings, weekends, and summer periods. Avoid any routing requiring more than a single transfer, except due to maintenance or other line closures.
