Igarapé Miri, Brazil

With a population of just 8,120,131, Igarapé Miri is a backwater in the Amazon basin where bureaucracy is a persistent headache and the tropical climate can be oppressive. Despite its location in the northern state of Pará, the city offers little to distinguish it from the countless other remote river towns scattered across the region. The local economy revolves around modest agricultural activities like cassava and açaí production, providing few opportunities for ambitious transplants. Unless you're a hardened Amazonian pioneer seeking a quiet, simple life, Igarapé Miri is best avoided.
