I need to travel from Charles de Gaulle airport to Montparnasse to catch a TGV (Train à Grande Vitesse or "high-speed train"). What is the best and fastest method to do that? Train?

I only have an hour and 30 minutes between arrival at CDG and the pre-booked TGV departure from Montparnasse (I didn't do the booking myself). I am concerned that may not be enough time.


An hour and a half is not even within the realm of possible. Where is your TGV going? You might want to look into changing the train ticket to a train leaving from CDG. Trains that leave Montparnasse usually have an alternative line from CDG. If you're going towards Tours/Bordeaux or Le Mans/Rennes you should be able to take the train right in CDG.

    Thank you. The train ticket to Nantes was booked by someone else. I'll have to try to get them to change the ticket. Many thanks for your advice. You've confirmed what I feared. Oct 29 '17 at 11:33

    It appears that there are in fact direct trains from CDG to Nantes. Oct 29 '17 at 15:00
