Aéroport Charles de Gaulle 1 is one of two railway stations at Charles de Gaulle Airport, the primary airport for the Paris region and the largest in France. The station is served by RER B and CDGVAL.
Despite being named after Terminal 1, the station is actually located relatively far from the terminal, but it can be accessed with a short ride on the CDGVAL. Terminal 3 can also be accessed from this station by a five-minute walk on a 300-metre pathway. The station is located inside Roissypôle, a development that includes office buildings, shopping areas, hotels, and the primary bus station for the airport. Because of its location, the station is named Terminal 3 Roissypôle on maps of the CDGVAL system.
