Those who prefer sports without an instructor should prepare for the popular Konstanz Old Town Run: Jogging freaks will run the four kilometres in just 13 minutes. Why not train together and register as a team?
At the “Hörnle” beach you can play beach volleyball, chess, table tennis, badminton and ring tennis. You can practice your putting while playing minigolf nearby too.
On the Bodanrück peninsula (20 minutes by car) you can play real golf – 18 holes, and, of course, only in compliance with the rules of etiquette and the corresponding wherewithal.
