Is Søborg safe for solo female travelers?

Pretty safe. I have not felt unsafe in the 3 years i have lived here. Sometimes there is fireworks at night but it usually is just a single instance and it is not very often. Søborg have at great community with nice shops and interesting events.

Any place, sadly, cannot be totally safe. Soeborg in Denmark, just outside Copenhagen, is very safe. Of course as a woman there is always the fear of anything could happen, but I feel safe walking alone (day or night, after nights of clubbing), the public transport is very safe alone too.
