Ushuaia is the capital city of Tierra del Fuego Province, Argentina. It is commonly regarded as the southernmost city in the world. Ushuaia is located in a wide bay on the southern coast of Isla Grande de Tierra del Fuego, bounded on the north by the Martial mountain range and on the south by the Beagle Channel. It is the only municipality in the Department of Ushuaia, which has an area of 9,390 km2. Ushuaia has long been described as the southernmost city in the world. While there are settlements farther south, the only one of any notable size is Puerto Williams, a Chilean settlement of some 2000 residents (mostly families of the nearby military bases). Puerto Williams also calls itself the world's southernmost city but this claim is dubious as the Chilean government itself defines a city as an urban entity with more than 5,000 inhabitants.
Tourist attractions include the Tierra del Fuego National Park and Lapataia Bay. The park can be reached by highway, or via the End of the World Train (Tren del Fin del Mundo) from Ushuaia. The city has a museum of Yámana, English, and Argentine settlement, including its years as a prison colony. There are a number of ski areas close to Ushuaia, including Glacier El Martial and Cerro Castor. Opened in 1999, Cerro Castor is the southernmost ski area in the world. On Cerro Castor, it is possible to ski just 200 m (660 ft) above sea level. The summit reaches an elevation of 1057 meters (3468 ft) above sea level, and consistently cool temperatures allow the longest skiing season in South America.
As in most of Argentina, football is a popular sport in Ushuaia, and in 2010 the TV show FIFA Mundial did a story about the sport's development in this locality.
