Charles de Gaulle to Bayeux

If I’m not mistaken, there are no direct trains from CDG to Bayeux. All trains to Bayeux from Paris leave from Gare St. Lazare. After a long flight, I’d suggest taking a cab from the airport directly to the station. Otherwise, it’s taking the RER B from the airport, changing to Metro line E and then hoofing it to Lazare with your luggage.

Philip is right - no direct trains. You can take the RER into town and transfer to the metro for Gare St Lazare, or take a taxi.

Taxis are fixed-rate from the airports into town. From CDG to Gare St Lazare is 53€ for up to four people and your luggage.

Philip and Kim are right. Despite dozens, even hundreds, of threads on this forum the SNCF still hasn't laid the tracks and started train service between CDG and Bayeux. ;-)

Taxi to Gare St-Lazare and train to Bayeux is the simplest way to go. The taxi will cost 50 euros. You could save a little money (assuming there are two or three of you) by taking the RER (commuter rail) to Gare du Nord and then Metro to Gare St-Lazare. But that will probably take longer and certainly be less comfortable, requiring you to haul your bags on and off trains.

Small correction: the taxi will cost 53€. The prices went up.

You can take direct train from CDG to LeMans where you can transfer to train to Caen and Bayeux. No need to go through Paris.

RoissyBus runs a direct shuttle from CdG to Opera, a five-minute walk away from Gare St-Lazare. It will be nearly as quick as a taxi -- traffic congestion treats everyone equally -- and a good deal cheaper. In normal times there are several runs an hour.

The cautious traveller might check directly with the company nearer to departure to see about schedules in these uncertain times.

This is great thanks. We doing this in October and I’m curious if we land at 8am at CDG and take a taxi. How much time do we need to leave ourselves for a train departure? Would an 11am train be cutting it to close? Or should we fly into Orly? We are coming from Naples Italy

We rented a car and drove to Bayeux from Paris. If I were starting from CDG, I would spend the first night near Monet’s home and garden in Giverny and then drive to Bayeux. We stayed at historic Lion d’Or in Bayeux and the hotel arranged a tour of US battlefields. We drove to the Canadian and British beaches on our own. I have heard good reports about Overlord Tours. Don’t miss seeing the Bayeux Tapestry, 11th century.

Hotel recommendation for Bayeux:
Hotel d’Argouges. A RS recommended hotel where we’ve stayed 6+ times. Love it. In the center of town, very quiet, free pkng, family owned, friendly helpful owners and staff, charming, lovely gardens, large rooms and large bathrooms, very clean, comfortable beds, good linens and pillows, a very good, free breakfast included. Highly recommend.

@ edryer4356, you really should have started a new thread with your questions for a couple of reasons. People may miss your question and if they do answer it will throw the original poster's thread off course. I am going to risk that now and go ahead and answer to the best of my knowledge.

"How much time do we need to leave ourselves for a train departure?" 3 to 3.5 hours between scheduled arrival time and departure from Orly and typically 4 hours from CDG.

"Would an 11am train be cutting it to close?" Maybe not because you will not have to go through passport control. I think 3 hours might be enough.

"Or should we fly into Orly?" Taxi from CDG to Gare St-Lazare train station is a fixed rate of 53€. Taxi from Orly is 37€. The rates are fixed and are for four passengers and their luggage. Mass transit is easier from CDG. The taxi ride is just about the same if there is no traffic. Which route is more likely to have traffic on any given day is something that maybe a local person will answer,

Thanks JHK,
Yeah I should post that in another thread didn’t want to high jack the OP. Thanks for answering
