Paranaguá, Brazil

This port city is not for the faint of heart. With a population of just over 107,000, Paranaguá is best known as the gateway to the state of Paraná, exporting over $4.3 billion in goods annually. However, the high humidity and frequent cloud cover can make the subtropical climate feel oppressive, and navigating the area's bureaucratic headaches is a persistent challenge. Those drawn to Paranaguá are likely seeking an authentic Brazilian experience outside the tourist hubs, but the tradeoffs may prove too much for many.
