Situated on the Beagle Strait, Ushuaia is the largest city in ArgentineTierra 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.
In the late 19th century, the land that is now called Ushuaia was inhabited entirely by Yamana Indians and a handful of missionaries. At the time of writing (October 2005), there is allegedly one pure-blooded native-speaking Yamana Indian left. An excellent book on the history of the Yamana and their demise is The Uttermost Part of the Earth by E. Lucas Bridges, the son of one of the early missionaries. His father, Thomas Bridges, documented what he could of the Yamana language and found that it had a far larger vocabulary than the English language. Darwin, who famously sailed through the Beagle Channel, thought that the Yamana, were "the missing link".
Today the town is growing fast as a result of increased tourism since the 2002 economic crash. The government has encouraged this growth by designating Tierra del Fuego a virtually tax-free zone to encourage people to settle (many of the inhabitants of today's Ushuaia come from Chaco, in the north of Argentina). The cost of living however, is relatively high as all goods have to be transported long distances, usually by container ship. Inflation is rampant even in USD terms, expect your guide-book to be well out of date and prices to be double or triple a few years ago.
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.
There are daily flights to Ushuaia – Malvinas Argentinas International Airport (USH) on Aerolineas Argentinas  and LAN flights  from Buenos Aires. LAN Chile, through its LAN Express services, flies daily from Santiago de Chile, stopping over in Puerto Montt and Punta Arenas. Flights can be booked from the Aerolineas Argentinas  office, as well as from some local travel agencies. The local LAN Chile  representative is the Rumbo Sur travel agency. LAN Chile tickets can be purchased online; With Aerolineas Argentinas  you can make a reservation online but the ticket must be purchased in person at an Aerolineas office within 24 hours (Jan 2008).
Buses from/to all destinations (apart from Puerto Natales) all stop at Rio Gallegos. It can be cheaper to just buy a ticket to Rio Gallegos and purchase an onward ticket from there. The ride from Rio Gallegos involves crossing into Chile, a ferry crossing, and back again into Argentina and is advertised as taking around 12 hours (680 pesos as of December 2014; NOTE: change money before getting to Rio Gallegos; offered only 9 pesos per dollar in RG, compared with 11 in El Chalten and 11.5 in Ushuaia *now 13ARS per 1 USD Jan '15 in Ushuaia) However, it is often longer if there are delays at the borders or if the ferry is delayed by inclement weather.
There are city buses within Ushuaia, but they only reach few of the tourist attractions. They are good to get to Playa Larga, for example, or from one part of the center to another, along the east / west axis.
Tours / transport to the main tourist attractions can be booked through the Tourist Office (on San Martin) or through many of the hostels. Regular minibuses leave for the National Park, Glaciar Martial, the trailhead of Laguna Esmeralda, or other places, from a parking lot at the corner of Maipu and Fadul.
Taxis are another option, costing, for example, Ar$50 to get from the city centre to either the airport or Glaciar Martial. There are also several car / bicycle hire companies.
