Europe is generally safe for solo female travelers. The levels of safety can vary somewhat between different countries and cities, but overall, most parts of Europe are well policed and the crime rates are relatively low. Public transportation is well-organized and usually secure. However, as with any location, it is important to stay vigilant, particularly in crowded places and at night. Standard safety precautions apply: avoid isolated areas, do not flaunt valuables, be aware of your surrounding, and use common sense.
