Drive CDG to Normandy or Train it?
 

We fly into CDG early morning and plan to spend a night in Bayeux and then head back to Paris. We were thinking of taking a train from CDG with our luggage but now we are not sure if renting a car would be better. Maybe rent it from CDG and then drive back to CDG to get on a train into Paris. Any thoughts? Thanks!

What is the purpose of your trip to Normandy? If you want to see Bayeux you can use a train. If you want to see the D Day beaches, cemeteries and memorials - you can;t do that via public transit - you will either have to rent a car or take a tour.

And I believe you would arrive there too late for a tour the first day - and if you take a tour the second day you wouldn;t get back to Paris until night (there is a LOT to see).

That said, I don't reco driving a long distance after coming off an overnight flight - most people are just too jet lagged for it to be safe.

Must you do this on your arrival or could you do it at another point in the trip.

You cannot take a train from CDG to Normandy; you must go into Paris to the Gare St.Lazare to get a train to Normandy.

We are flying from Rome into CDG. We want to see all the WWII sites. The cost of renting a car in Caen is about the same as getting it from CDG, so thinking that is best if we decide to drive it. We're thinking that dragging luggage on a train might be too much.

Since you won't have jet lag/travel fatigue, renting at CDG might be easier than taking a train.
Happy traveling!
