Chartres is generally considered a safe destination for solo female travelers. The city is famous for its Cathedral and it is often filled with tourists, providing a sense of safety. However, like any other tourist spot, it is important to stay vigilant as pickpockets and other petty crimes could occur. It is also recommended to avoid walking alone late at night in less populated areas. As a precaution, always keep an eye on your belongings, follow local advisories, and maintain a low profile to prevent unwanted attention. Overall, the French are very helpful especially if you show effort in speaking their language, even if it's just a few basic phrases. Most residents communicate in English, especially those who work in the hospitality industry. Public transport like buses and trains are safe and reliable, but always check the timetable especially in weekends as frequency might decrease.
