Ushuaia
Ushuaia (population 87,000; the southernmost city in the world — officially at 54.8° S latitude, though the Chilean settlement of Puerto Williams (population 2,500) at 54.9° S is technically further south; Ushuaia is the capital of the Argentine province of Tierra del Fuego, Antarctica and the South Atlantic Islands) is universally known as "el fin del mundo" (the end of the world) and sits on the Beagle Channel — the famous waterway named after HMS Beagle, the ship on which Charles Darwin sailed through this exact passage in 1832-1833-1834, documenting the flora, fauna and indigenous peoples (the Yámana (Yahgan) people — the southernmost indigenous people on earth, who inhabited the Beagle Channel islands and the Cape Horn archipelago for at least 10,000 years before European contact, living in the near-freezing temperatures year-round wearing little clothing, insulated by a thick layer of body fat and constant application of seal and penguin fat to their skin) that contributed directly to his theory of evolution. The Beagle Channel (the 240-km-long waterway connecting the Atlantic and Pacific Oceans between Tierra del Fuego and the islands to the south, named by Vice-Admiral Robert FitzRoy for HMS Beagle in 1832) separates Argentina (to the north) from the Chilean islands of Navarino and Hoste (to the south). Ushuaia is the primary gateway to Antarctica (the vast majority of tourist Antarctic cruises depart from Ushuaia — approximately 80,000 passengers per year; the 2-day Drake Passage crossing to the Antarctic Peninsula is included in all Ushuaia-Antarctica itineraries). The Tierra del Fuego National Park (Argentina's southernmost national park — the terminus of the Pan-American Highway (the road system that runs 30,000 km from Prudhoe Bay, Alaska to Ushuaia)) and the penguin colonies of the Beagle Channel islands (the Magellanic penguin (Spheniscus magellanicus) and Gentoo penguin (Pygoscelis papua) colonies accessible by boat from Ushuaia harbour) are the primary day-trip attractions.
