Salinas, Brazil

This small airport town has a population of just 40,178, and that's about all it has going for it. With no scheduled flights, residents are essentially stranded, relying on the 11 km drive to the city center for any semblance of connectivity. And that's when the bureaucratic headaches don't get in the way. Safety is also a persistent concern, given the airport's history of accidents. Unless you're content with isolation and a heavy administrative burden, Salinas is unlikely to be the Brazilian haven you're seeking.
