Surrey is generally a safe city to visit for solo female travelers. While crime does exist, as in any city, common areas frequented by tourists and most neighborhoods are safe. Daytime and early evening travel is generally very secure, but it's recommended to exercise extra caution at night, just as in any unfamiliar place. Utilizing trusted public transportation is assured, but it's always wise to stay observant and be aware of one's surroundings. The local residents are friendly and helpful, and law enforcement is trustworthy and reputable. Keep in mind to use the usual precautions that one would in any other city.
