Bad Honnef, Germany

With a population of 26,025, Bad Honnef is a spa town in Germany that has become a magnet for the affluent. The mineral springs that put it on the map in the late 19th century have since transformed it into a conference hub and retirement haven, with over a quarter of its residents being pensioners. While the town's proximity to Bonn once made it attractive for politicians, its bureaucracy is now a persistent headache. Overall, Bad Honnef seems tailored for the wealthy and well-connected looking to while away their golden years in a quaint German setting.
