Train from Charles de Gaulle (CDG) airport to Bayeux

There are no direct trains from CDG to Bayeux. Where did you read that? You can go Entirely by long-distance train from CDG to Bayeux but it is a long, circuitous route with at least one change. The faster and better way to make that trip is a taxi or mass transit to Paris, specifically to Gare St Lazare, and take the train from there. You can get ticket pricing and schedules, etc. at https://www.sncf.com/en.

Please post the link to the page on the CDG website where you read that.

While it is possible to take the train from CDG to Bayeux, it will require from 5 to 6 hours and no fewer than 2 connections.

Taking a taxi/RER into Paris and departing from St Lazare is much easier and a lot faster.

The website I was looking at was trainline.com. It may not be the best way but it is one way if you are going to Bayeux. It is not a direct line as I am sure it makes at least some stops along the way. I was just wondering if anyone has ever taken it before to see if it would be worth it.

I just Googled "Trainline CDG to Bayeux" and while, yes, it does say on the results page that there are trains from CDG to Bayeux, with travel times starting at 3h 14 m, if you look closely at the results the suggested trains are just the RER to central Paris, then an onward SNCF train from Gare St-Lazare. In other words, exactly what everyone above is suggesting.

There is no direct train that you are missing from CDG to Bayeux and the other posters here have warned you correctly.

If you don't start from Gare St-Lazare in central Paris -- which is the only logical thing to do if you want to travel from the Paris area to Bayeux by rail -- the only other way from CDG to Bayeux by mainline railway are truly indirect artificially constructed routings that will have you going to places like Lille (225 km north of Paris and not at all on the way to Bayeux) and will add at least 1 to 2 hours longer than if you had just gone to central Paris in the first place.

Thank you for your advice; I am going to take it! Thanks again, Debbie

You are going to take what? The train from CDG to Bayeux or you are going to go into Paris?
Anyway, just to be clear (i) Trainline.com is not CDG's website and (ii) if you take the trains from CDG, you will probably have at least two changes, the trip will take about 5 hours and you will probably spend two or three times as much money as compared to going into Paris to catch the train. If you do take the route from CDG, please report back so we can learn how it went.
