San Juan Capistrano is generally a safe place to visit as a solo female traveler. It's a small, laid-back city in Orange County, California, known for its historic Californian mission and charm. The area has a reputation for being more well-off and safe compared to other regions. However, it's important to exercise everyday precautions, such as staying alert, particularly at night and sticking to populated areas, just as one would do visiting any other city.
