Ushuaia, Argentina

Capital City

With a population of just 82,615, Ushuaia may be the southernmost city in the world, but it's no tropical paradise. The tax burden is heavy, the bureaucracy a persistent headache, and the climate downright unforgiving - summers are cool and cloudy, while winters bring frequent snow and frost. Yet for adventurous types willing to brave the elements, Ushuaia offers access to stunning Patagonian scenery and a chance to live on the literal edge of the world. This is a city for the hardy, not the faint of heart.
