Really popular tourist destinations are usually well known for good cause, they are well worth seeing. A problem to me is spending too much of my vacation traveling too much to see too few of these "gems". I like to keep my travel time to a minimum and spend more time afoot experiencing an area. I supposed I developed that habit living two army tours in Germany.
I really like the posts by Ms. Jo of Frankfurt as she points out so many possibilities near Frankfurt. I still plan to some day make a small circle of stops around Frankfurt just to get a feel for the area. I have googled and bookmarked many of the possibilities.
Many areas of Germany have a wealth of towns worth visiting. I like Franken with Würzburg, Aschaffenburg, Nürnberg, Bamberg, Rothenburg, Bad Windsheim, etc. Dating back to my army days, I use the "ADAC StraßenAtlas" to find places they think are sehenswert (worth seeing). It is a street atlas but it also has rail routes indicated. I am not a day tripper as I find it better to stay overnight in a place and experience it. I recently added a new destination to my overnight stop list: Kulmbach. It is not a spectacular "tourist destination" but what a nice overnight to see the castle (Renaissance court yard and tin figure museum) and roam its streets with attractive old buildings. I first heard its name as a famous beer brewing center near Nürnberg, when I was stationed there.

Anyone else have overnight recommendations in Franken or an area on which they like to focus?
