Tangará da Serra, Brazil

The airport here doesn't even see scheduled flights, so getting in and out of this place is a headache. With a population of just 112,547, Tangará da Serra is a sleepy backwater, located 13 km from the city center. The bureaucratic hassles of living here are a persistent annoyance, as the airport is the only real gateway to the outside world. If you're looking for a quiet, remote life off the beaten path, this might fit the bill. But for most, the isolation and lack of infrastructure make Tangará da Serra a tough sell.
