Pennsylvania is generally a safe destination for solo female travelers. Like any travel destination, it requires common sense and vigilance, especially in larger cities like Philadelphia or Pittsburgh where petty crimes can occur. However, many parts of the state are very safe to visit, including small townships and rural areas. The people are generally friendly and helpful. It's always worth noting the necessary safety precautions, such as avoiding deserted areas at night, staying alert in crowded places, and not flashing valuables.
