Ouro Preto generally offers a safe environment for solo female travelers. As a historic and touristic city, it is accustomed to welcoming visitors from all over the world. However, like anywhere, it's important to maintain basic safety precautions. Avoid isolated areas, especially at night, and be aware of your surroundings. Pickpocketing may occur in crowded touristic spots, so always keep your belongings secure. Local people are usually friendly and eager to help. Language may sometimes be a barrier as not everyone speaks English, but understanding basic Portuguese can be really helpful.
