How do I get fro CDG to Caen by train? How much does it cost? How long does it take? How often do the trains run? I arrive on Sat 23 April at 13:00 and would like to be in Caen by sundown.
Paris to Caen requires a TGV train from Gare Saint Lazare in Paris. Tickets for TGV trains from Paris to Caen. Paris to Caen by TGV takes just over 2 hours and costs about 36€ as of 2016.
Take a RER B train from CDG to Paris Gare du Nord. Transfer at Gare du Nord to RER E direction Haussmann-Saint-Lazare until the terminus (Haussmann-Saint-Lazare). At Gare Saint Lazare you'll need to make you way up to the Grandes Lignes (Main train lines) at ground level and look on the departures board for your TGV train to Caen.
