Perched on the ragged southern edge of Argentina, where the snow-capped Andes fall away into the churning sea, Ushuaia has a frontier town feel to it, and serves as the base for expeditions into the icy waters of Antarctica.

Antarctica is the world’s last great wilderness, an alien landscape of snow-covered mountains, jagged icebergs and extraordinary wildlife. Visiting at the beginning of the cruise season in October or November means bigger icebergs and pristine snowy landscapes, along with the chance to see breeding elephant seals. There may still be sea ice around the Antarctic Peninsula, and temperatures are cold.

Remote and virtually uninhabited, the island of South Georgia is a beautiful and fascinating place. The landscape of jagged, snowy peaks and dramatic fjords is home to an abundance of penguins and seals, as well as ghostly abandoned whaling stations and the grave of Sir Ernest Shackleton.

The rugged and windswept Falkland Islands make for a fascinating stop on the way to or from Antarctica. Over 80% of the population lives in the capital, Stanley, though humans are far outnumbered by other creatures, including penguins, sea lions and albatrosses.
