Explore the Arctic and the Antarctic. Two very different places and polar opposites – the Arctic to the North and the Antarctic to the South. USA River Cruises offers extraordinary opportunities to discover these last frontiers. Remote and thrilling, these places are home to deep blue pristine waters, towering glaciers, and curious creatures. Your Antarctic cruise ship is the luxurious base camp early explorers could only dream of. Dive in and try a polar plunge for an unforgettable experience, or lock eyes with a curious King penguin on your Antarctic cruise. Paddleboard past a glacier. These sensitive areas are carefully controlled, and we have only partnered with cruise lines that care for the world they travel – leaving only footprints in the snow. These small ship cruises offer an up-close experience that will fill you with awe. Look up and see the stars as the ancients did before the modern world dimmed their view! This is a world of exhilaration so why not take a polar cruise and dive into the adventure!
