This beautifully quaint Black Forest German town is famous for its curative waters. It attracts celebrities, royals, and (in our case) the tourist who just happens to stop by on the way back from Switzerland. A drive through the Black Forest is beautiful. I also understand where some fairy tale inspirations may have originated (spooky at dusk)
Close to the border with France, Baden Baden (meaning "bath") is definitely a must-see if you are in the area.
