When visiting Rio de Janeiro there are plenty of tourist activities to do throughout the city. One activity that is not listed in the guide books as an option is a tour of a Favela! A favela is Brazil's version of the United States slums. If you have ever seen the movie, "City of Gods," then you know what I am talking about when I mention the word favela. Favelas are built upon the hills of Rio De Janeiro, and are home to some of the poorer people in Brazil. Favelas are notorious for being ran by drug lords, and having huge gang wars break out between rival gangs over territory and drug trade. Most of the time the police have a hard time controlling what goes on inside a favela.
