6Ushuaia, Argentina

Whether you fly into the world’s southernmost international airport, ride the End of the Worldtrain, or take an epic road trip through Patagonia, reaching Ushuaia is an adventure in itself.
Perched on the southernmost tip of Argentina and hemmed in by the snowy peaks of the Tierra del Fuego National Park, Ushuaia is ground zero for glacier hikes, Beagle Channel excursions to see penguins and seals, and Antarctica cruises.
