I can walk alone in the dark in a dress without getting cat called at least 90% of the time, so I feel quite safe. Most people are young and very nice and help when something is up. So I think you can say it's quite safe to travel alone

You can walk on the streets any time of the day/night. Go on walks, hikes... The city is small but well active thanks to a large student community and a big university campus. The train station is also safe as it resides in the center of the town and police is always there.

Göttingen is a small cute city in the middle of Germany. It's very safe, but the busses in the evening are not driving that often. There is many police in evening in Göttingen, so it's very safe. But you should not ride your bicycle without light or, when you are drunk.

Göttingen is a university city in Germany. There are many young people who speak English and are willing to help. The public transportation is good, although there are often changes because of several roadworks.
