Ushuaia has long been described as the southernmost city in the world (others say Punta Arenas is). Ushuaia's name comes from the language of the yámanas or yaghanes indians, its original inhabitants, and means "bay that penetrates westward." Ushuaia is the capital of Provincia de Tierra del Fuego, Antártida e Islas del Atlántico Sur Province, Argentina. A busy port and adventure hub, Ushuaia is a sliver of steep streets and jumbled buildings set between the Beagle Channel and the snowcapped Martial Range. Ushuaia takes full advantage of its end-of-the-world status as an increasing number of Antarctica-bound vessels come in to port.
