Safe and enjoyable solo travel for women is largely about being sensible, especially so if you are visiting an area that is not considered safe to visit. Even if you are single, many experienced women travelers suggest wearing a wedding ring and inventing a fictitious husband to avoid unwanted attention from men. If you do ever feel threatened, yelling or making for the nearest public building or crowded place should work. Women only subway cars are available in many countries, including Japan and India, and women travelers should be sure to work only with a reputable and recommended taxi or tour company. Carrying a tube of mace may be an option, although getting it through airport security can be a problem. But simply being aware of your surroundings, and letting someone know where you are going and when you’ll be back can make sure you stay safe.
