Charles de Galle to Bayeux

To get from CDG to Bayeux, you need to get to the train station in Paris that serves Normandy which is Gare St Lazare. To get to the train station, I suggest taking a taxi. The current fare for up to 4 people is 56€. I buy tickets ahead of time and keep them on my phone because I do not like dealing with getting tickets at the station but others prefer to wait. A pre-bought ticket could be nonrefundable; you will have to look at the ticket terms when you purchase it. You could wait and buy the ticket online while heading to the train station. Tickets bought closer to travel date are generally more expensive. If you buy ahead of time, I suggest allowing four hours between your flight's ETA and the train's scheduled departure time.

Last May we booked our tickets in advance, but made them changeable. It was a savings over buying on the day. We managed to get through immigration quickly and were able to transfer our tickets to an earlier flight. It was super easy to make the change in tickets at the station. There is an option to take the Metro, but it is not direct. We opted to take a taxi to Gare St. Lazare. We were lucky and didn’t run into any traffic and were at the train station in ~35 minutes. However, if there is traffic, it could take up to an hour.
