As a guide, I would like to emphasize that in Hereford, as in any other city, there are areas that are less recommended for safety reasons, especially at night. However, it is important to emphasize that Hereford is generally a safe, friendly and welcoming city known for its historic charm. If you have specific safety concerns, it is always a good idea to do some research and possibly check with local authorities or your accommodation provider to make sure you are staying and traveling in the safer parts of the city.
