A cruise to Antarctica is a bucket-list event, and it's an unforgettable thrill to travel to such a remote location. It also has to be timed right. The Great White Continent is a stunning place to cruise in the Southern Hemisphere’s short summer: December through February. The longest itineraries are two to three weeks aboard expedition ships with ice-strengthened hulls and depart from Ushuaia, Argentina, to visit South Georgia, the Falklands, and the Antarctic Peninsula. Shorter routes may focus only on the Antarctic Peninsula, while larger mainstream ships may include the Falkland Islands on a circumnavigation of South America. The true expedition ships carry Zodiac landing craft and a team of experts who escort passengers to remote islands and scientific research stations for close-up views of penguins, elephant seals, and whales.
