A quick question: I'd like to go, by train, from Paris to the Van Gogh landmark of Auvers-sur-Oise. Suggestions?
You can go from Gare du Nord

GREAT day trip from Paris. Most routes require a change of trains. We did it on a Saturday in Spring a few years ago when there was a morning direct train and a return train to Paris direct at 6.
