I‘ve been living in Kiel for my whole life and always felt really safe. Would recommend crowded areas by nighttime this always helps to feel protected. There are also police officers by the central station so whenever you feel uncomfortable waiting for public transportation you can talk to them.

It really depends on the area you’re in. Areas you shouldn’t travel to alone as a woman especially in the dark are: Mettenhof and Gaarden. Other than that I’d say it’s the same to most German cities.

I would say Kiel is a safe City over all. The police and other people are friendly and happy to help you, from what I experienced! At night I would avoid to hang out near the train station since there are some homeless people and drug addicts living there. The public transport is pretty safe but I would still stay aware of you surroundings.
