For snowbirds, a trip to the coldest continent on the planet is the ultimate getaway. Many cruise lines invite you to travel the very ends of the earth, where you'll spot penguins, seals, whales, and so much more. The intrepid traveller can even show off their cold-weather chops with a frosty polar bear plunge into the icy seas. Although not technically a country of its own, the continent does offer visitors souvenir stamps in their passports. And yes, it is a picture of a penguin, which pretty much makes it the coolest passport stamp ever.
