Ushuaia is the capital of Tierra del Fuego, Antártida e Islas del Atlántico Sur 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 (3,625 sq mi).
The Selk’nam Indians, also called the Ona, first arrived in Tierra del Fuego about 10,000 years ago. The southern group of the Selk’nam, the Yaghan (also known as Yámana), occupied what is now Ushuaia, living in continual conflict with the northern inhabitants of the island.
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. 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 (Staten Island).
