Australis: Punta Arenas to Tierra del Fuego

Just the name of the Gauchos, Penguins, and Glaciers cruise, a five- or six-night adventure aboard a cruise ship limited to between 136 and 210 passengers, gives a hint that this expedition to southern Patagonia is far from your usual float. From October to April, sail from Punta Arenas in Chile to Argentina's Ushuaia and back with zodiac ports of call in Tierra del Fuego and Cape Horn, the last territory before Antarctica. Sailors make landfall at the world's largest colony of king penguins and poke about among the looming – and often calving – glaciers off Cape Horn. Along with the standard open bar, a barbecue with gauchos at an estancia (a cattle ranch) is also included in the price.
