Typically a trip to Antarctica takes 7 to 12 days, considering the time the cruise ship takes from South America over and a few days along the coast. You also have the option to fly over from South America. Then a cruise takes about 7 days along the coast to different places there. Many cruises also stop at the Falkland Islands and/or at South Georgia Island, these are usually a little longer. Getting to the start and point of the cruises takes a little time and a few extra days need to be factored in along the way.
