The northern-most tip of the world's wildest continent is incredibly lush by Antarctic standards, able to support a hugely diverse variety of plants and animals. During the summer, humpback, minke and occasional blue whales come to the bays around the Antarctic Peninsula to gorge on pink krill. Albatross, skuas, gulls and penguins are also seen in huge numbers, feasting on the rich pickings from the sea.
Expedition vessels bound for the Antarctic Peninsula sail out of Ushuaia - southernern most town in the world.
The jury's out as to whether any of us should be visiting this pristine environment. Until scientists make up their minds, you can help by always travelling with members of the International Association of Antarctic Tour Operators who adhere to a strict environmental code and limit passenger numbers.
