The Antarctic Peninsula – the main peninsula closest to South America – has a human history of almost 200 years, with explorers, sealers, whalers, and scientists who have come to work, and eventually intrepid visitors coming to enjoy this pristine and remote wilderness. It is a region of protected bays, unscaled snow-capped mountains, vast glaciers and a few places where whalers or scientists have worked. Just as irresistible are the many Gentoo and Chinstrap Penguin colonies, the seals basking on ice floes, the whales and orcas.
