Antarctic Peninsula travel guide

The Antarctic Peninsula is the northernmost part of the mainland of Antarctica, and almost the only part of that continent that extends outside the Antarctic Circle. It lies in the Western Hemisphere, facing South America, making it a part of West Antarctica. It extends from a line between Cape Adams (Weddell Sea) and a point on the mainland south of Eklund Islands, to Prime Head (63º13'S).
The first sighting of Antarctic Peninsula is contested but apparently occurred in the 1820s. Agreement on this name by the US-ACAN and UK-APC in 1964 resolved a long-standing difference over the use of the American name "Palmer Peninsula" or the British name "Graham Land" for this feature. (Graham Land is now that part of the Antarctic Peninsula northward of a line between Cape Jeremy and Cape Agassiz, whilst Palmer Land is the part southward of that line. Palmer Land is named for the American seal hunter, Nathaniel Palmer.) In Chile, the peninsula is officially referred as O'Higgins Land, after the Chilean patriot and Antarctic visionary. Other Spanish countries call it "Península Antártica", among them Argentina (while also calling it "Tierra de San Martín"), which has more bases and personnel there than any other nation.
