Kaiserslautern’s northern neighbour Otterberg boasts an almost intact old town, something Kaiserslautern does not have after countless invasions. The tourist information gives out English pamphlets describing a nice two-hour walking tour of the city. With 24 sights including an exceptionally lovely 12th century abbey church this is a very good half-day trip. The walking tour passes shops, cafés and a playground. It is 20 minutes by bus from Kaiserslautern to Otterberg’s Kirchplatz.
