Antarctica cruises roughly fall into three patterns. The shortest visit the Antarctic Peninsula, and by adding a few days, you can include the Falklands and Port Stanley, the capital, with its British stock living in such a remote place, pastoral settings and possibly an out island for birds and penguins, including the rock hopper. Three weeks is required if adding remote South Georgia for its huge bird population and the Shackelton Expedition history. The White Continent is visually stunning: the land forms, icebergs with their range of colors, and the crystal-clear air. Visit remote research stations and meet various types of penguins, slumbering elephant seals, and sea birds. Temperatures ashore can be quite tolerable if the sun is shining, while the beginning and end of the season can be snowy. Weather permitting, disembark for Cape Horn, where the Atlantic and Pacific oceans meet.
