Coated in brilliant white ice, magnificent glaciers, and an exhibit of a habitat untouched by human life, Antarctica is a foreign world that holds the possibility for life-changing adventure and education. Although cross-country skiing and sub-zero tent dwelling are certainly within the realm of possibilities, cruises are also an excellent choice for those looking to keep luxury top of mind. Combine the comforts of home with the allure of a small-vessel exploratory expedition to see icebergs up close, native whales breaching the surface, and more.
