Travel from Paris airport to Bayeux

Assuming you are arriving from N America on an overnight flight, embarking on a 180 mile 3+ hour drive is probably not in the category labeled "good idea"

Taking a train and renting a car at Caen or Bayeau would be a much better idea.

Apart from a private helicopter, train is likely the 'fastest and easiest'

I'll agree with Joe. If arriving on a flight from North America, a drive on unfamiliar roads and highways in potentially heavy traffic for part of the way? While jet lagged? 3 1/2 to 4+ hrs worth of really bad idea. Consider instead taking a taxi to Gare St Lazare (flat fee €58 in official taxi) and then the train to Caen (direct train about 2 ish hours). Pick up your rental car there. About 30 minutes drive from Caen to Bayeux.

Fastest and easiest is train from Gare Saint-Lazare train station. If you drive, it is all highway, but the periphery roads around Paris can be bad traffic—particularly anywhere near rush hour. Once you are free and heading North of the city it is usually fine. A lot also depends on from where you pick up your car.

Appreciate your responses. Yes we are coming from N America and were worried about the long drive.

Not hard to take official taxi -lots of scammers at the airport trying to get you to go to an unofficial line- to Paris Gare St Lazare then to Bayeux via train . You can buy the ticket on the app once you're at the station.

Train is super easy to Bayeau and we found taxis right at station in Bayeau that took us to our bed and breakfast. Not sure about car rental in Bayeau as we only walked around city and did a Normandy tour which picked us up and dropped off at our B an B. advice about official taxi stand is spot on, many scammers just be assertive and will have no problems. Advice not to drive there is spot on. My son drove after five days in Paris and Said it was fine driving the roads but never would have done it after a flight. Enjoy your trip.
