Quark Expeditions has been the world leader in polar cruises and guided tours for over two decades and successfully operated many first-ever passenger trips to Antarctica, including the Circumnavigation of the Antarctic continent and the first Weddell Sea voyage. Antarctica is the great white continent and one of the last true wilderness areas on earth – largely unchanged since the early explorers. It’s home to the world’s greatest concentration of wildlife, where penguins, seals and whales are the only permanent residents.
