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. March is too late to see penguin chicks, and temperatures are getting colder, but it’s a great time to spot whales, with species including humpback, sperm and orca.

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.

The streets of Buenos Aires are redolent of a grand old European capital, lined with elegant architecture that wouldn’t look out of place in Madrid or Paris. There is also plenty of Latin passion on display: Argentina is the home of tango, that most electrifying of dances, and has played host to countless revolutions over the years.
