There is a lot of information about Paris Charles de Gaulle airport, but much less about Orly Airport. If you are staying in Paris, and flying out of Orly, here is how we got to Orly airport via OrlyBus.
Orly Airport via OrlyBus (Metro)
Take the Metro to the Denfort Rochereau stop.
When you get off the Metro, you simply follow the signs
The simplicity ends there. When you get outside, there are no more signs and it’s just confusing. Look around until you see this view and follow the guy with the backpack.
Once you round the corner, you will see the OrlyBus in the distance.
Keep walking past the buses and you will see the ticket machines.
Pay €8.30 (credit cards accepted). Wait for the bus to pull forward and board.
About 30 minutes later you will arrive at Orly.
Note that you can also take the RER to Denfort Rochereau. In one respect this is slightly easier, because as soon as you exit the station, you see the Orly Bus
An easy, and relatively inexpensive (€8.30), way to get to Paris Orly airport is via OrlyBus.
