Just the word ‘ Antarctica ’ is enough to set the imagination on fire . It ’ s the outermost edge of human endurance and exploration , and many trips to the world ’ s largest continent start in the Argentinian town of Ushuaia . When it comes to wilderness and adventure , the possibilities are endless , whether it ’ s rounding the legendary Cape Horn or sailing the treacherous Drake Passage . Furthermore , ethereal blue icebergs , pristine glaciers and vast , glistening seascapes make this part of the world one of the most unique . It ’ s a haven for animallovers , too — penguins , seals , whales and a myriad of birdlife all call Antarctica home — and ship captains will sometimes amend the route to maximize wildlife-spotting opportunities . These are just some of the many highlights to expect on Viking ’ s Antarctic Explorer voyage .
