This summer, my wife and I are renting a car from Orly for a 3-day trip to Normandy. We'll then be returning the car at Orly and are booked on a TGV train to Avignon from Massy station. Does anyone know the options for getting from Orly to Massy? If a taxi isn't too expensive, we'd probably try that. Are there any other good options? Any advice is greatly appreciated.
You can take the Orlyval to Antony from either Orly-Ouest or Orly-Sud.
Take the RER B from Antony to Massy-Palaiseau. It's a very short walk from there to the Massy TGV station. (Saint-Remy-les-Chevreuse is at the end of the line and is ten stops beyond Massy-Palaiseau.)
The fare on the Orlyval is €7.60/person. The fare for the RER B from Antony to Massy-Palaiseau is €1.55.
A cheaper but slower route would be to take the airport shuttle bus to the Pont de Rungis RER C station (€2.50) and the RER C from there to Massy-Palaiseau (€1.55).
According to viamichelin.com, it's about a 15-minute drive from Orly to the Massy TGV station. A taxi shouldn't cost too much for that short trip.
