Neiva, like many cities, has parts that are generally safe and parts that can be risky. As with any city you're unfamiliar with, you should stay alert and be vigilant, especially during the night time. Pickpocketing can be a problem in more crowded areas, so be sure to keep a close eye on your belongings at all times. Traveling by authorized taxi companies and avoiding isolated areas can help your stay be more secured. So overall, while there are potential risks, your visit can still be enjoyable if you take standard safety precautions.
