Tinos is quite safe for solo female travelers. Locals are generally friendly and willing to help, which can be a great reassurance when exploring alone. Crime rate is low, especially major crimes, and the island exudes a relaxed and protective atmosphere largely due to its unique community that values harmony and safety. Like any other location, it is always important to take general precautions like avoiding dark streets late at night and keeping your personal belongings safe, but generally, Tinos provides a great balance of safe, cultural, and adventurous experience.
