Ushuaia is the capital of Tierra del Fuego, Antártida e Islas del Atlántico Sur Province, Argentina, and the southernmost city of the country. Ushuaia claims the title of world’s southernmost city. 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 (3,625 sq mi). It was founded on October 12, 1884, by Augusto Lasserre and is located on the shores of the Beagle Channel surrounded by the mountain range of the Martial Glacier, in the Bay of Ushuaia. Besides being an administrative center, it is a light industrial port and tourist hub. Ushuaia is located roughly 1,100 kilometres (680 mi) from the coast of Antarctica.
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. Wildlife attractions include local birds, penguins, seals, and orcas, many of these species colonizing islands in the Beagle Channel. There are daily bus and boat tours to Harberton, the Bridges family compound, Estancia Harberton. Tours also visit the Les Eclaireurs Lighthouse. Les Eclaireurs is sometimes confused with the “Lighthouse at the End of the World” (Faro del fin del mundo) made famous by Jules Verne in the novel of the same name; but the latter lies some 200 mi (320 km) east of Ushuaia on Isla de los Estados (Island of the States).
