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.

Arriving on New Island's sandy beach, you'd be forgiven for thinking you were off the coast of Scotland. Yet a short walk over the crest of a hill reveals a colony of rockhopper penguins and black-browed albatross perched on a cliff. A small hut, originally built by stranded sailors, is now a museum dedicated to the history of the island.

West Point Island is located in the northwest of the Falklands archipelago, and is also known as Albatross Island thanks to the many black-browed albatross that nest on the spectacular cliffs. The island is also a working sheep farm, and is home to a large colony of rockhopper penguins.

Saunders Island is graced with some of the most dramatic scenery in the Falklands, including the sandy isthmus known as The Neck. The island also supports an incredible bird population, with species including black-browed albatross, black-necked swans and four different types of penguin.

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.

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.

Antarctica is the world's last great wilderness, an alien landscape of snow-covered mountains, jagged icebergs and extraordinary wildlife. December is the most popular month to visit, with temperatures at their warmest (by Antarctic standards), long hours of daylight (great for photographers), and wildlife active everywhere. Expedition trips will spend time exploring the Antarctic Peninsula, making several landings at various sites and cruising through scenic channels.
