Juína, Brazil

With a population of just 36,581, this remote outpost in central Brazil is a far cry from the glitz and glamour of Rio. Juína is a municipality in the state of Mato Grosso, home to the Iquê Ecological Station nature preserve and served by a regional airport. Bureaucracy is a persistent headache, as with much of Brazil, and the isolated location means access to services and amenities is limited. For those seeking an off-the-beaten-path experience in the Brazilian interior, Juína may offer an authentic taste of small-town life, but it's hardly a destination for the faint of heart.
