What is the best way to get from Paris to Rouen on Sunday May 31
Train is going to be the most economical and easy way to get there.
You will go from Gare Saint-Lazare to Gare de Rouen Rive Droite
I second Alexander’s advise, in case you have no plans visiting something in between the train remains the best way.
It is a straight shot Paris to Rouen by train and the train station in Rouen is an easy stroll from the historic center. We did it as a day trip easily.
Thanks for the advise. Are there any trains on Sunday?
Yes. Go to oui.sncf.com and you can see.
