Teresina, Brazil
We have 20 cities on this list and 10 of them are cities in Brazil. And while the country is beautiful, it’s a good idea to only visit places that are considered safe and very public. Venturing out of your safe zone or ‘comfort’ zone in Brazil is a dangerous concept as you might encounter issues such as cities like Teresina, which boast more murders than just about any other city in the world. It’s not exactly an attraction highlight.
