Northern East France - any fun / interesting roads?

[Wollemi]

We are going on a trip to the Champagne region just south of Riems. We are using the Channel tunnel and stopping over near Calais.
So we have all day to get our destination and wondered if there were are roads that were fun to drive, or are they all flat and straight?

if we can't have fun and twisty, what about roads which are more scenic and pretty? Nice villages? Places to visit en-route - other than the old circuit at Gueux which we have already put on the route.

Thoughts and suggestions please?
