 A leisure drive thru this area of Germany is well worth the time.

If you are going to Paris by automobile, you may want to incorporate seeing the Black Forest area on the way.

Speaking about driving to Paris. France has an "autobahn"-highway from the German border into Paris. It is a toll route and is quite expensive. On a schedule? Take this highway, otherwise, do as the French do, ignore this toll road and use "secondary" roads. About the only cars I observed on this highway did not have French plates.
