Tierra del Fuego, a more or less triangular island separated from the southernmost tip of the South American mainland by the twists and bends of the Estrecho de Magallanes, is indeed a world unto itself. The vast plains on its northern reaches are dotted with trees bent low by the savage winds that frequently lash the coast. The mountains that rise in the south are equally forbidding, traversed by huge glaciers slowly making their way to the sea.
The first European to set foot on this island was Spanish explorer Hernando de Magallanes, who sailed here in 1520. The smoke that he saw coming from the fires lighted by the native peoples prompted him to call it Tierra del Humo (Land of Smoke). King Charles V of Spain, disliking that name, rechristened it Tierra del Fuego, or Land of Fire.
Tierra del Fuego is split in half. The island's northernmost tip, well within Chilean territory, is its closest point to the continent. The only town of any size here is Porvenir. Its southern extremity, part of Argentina, points out into the Atlantic toward the Falkland Islands. Here you'll find Ushuaia, the main destination, on the shores of the Canal Beagle. Farther south is Cape Horn, the southernmost point of land before Antarctica (still a good 500 miles across the brutal Drake Passage).
