Situated on the Beagle Strait, Ushuaia is the largest city in Argentine Tierra del Fuego, and arguably the southernmost city in the world. In the past, the town has been a missionary base, penal colony and naval base for the Argentine navy. Ushuaia is now a major tourist town, complete with casinos and nice restaurants, and commonly used as a base for hiking, winter sports and cruises to Antarctica. Climate-wise, Ushuaia is warmer than many assume; although (arguably) the southernmost city in the world, it is no further south than Belfast is north, and temperatures rarely drop below -10°C. However, summers tend not to climb much above 12°C and, as in all of Patagonia, strong winds add a significant wind chill factor. http://wikitravel.org/en/Ushuaia
