Porto Nacional, Brazil

This airport town of 1.26 million people offers little in the way of scheduled flights or reliable transportation. The airport is a mere 2 km from the downtown, but it currently has no scheduled service, leaving residents largely isolated. Bureaucracy is a persistent headache, as the airport has no official website or published flight information. For those seeking a remote, off-the-grid experience, Porto Nacional may be a viable option, but it's hardly a destination for the average traveler.
