21-Day Antarctica, South Georgia & Falkland Islands

Glamorous and gritty, Buenos Aires is two cities in one. What makes Argentina's capital so fascinating is its dual heritage—part European, part Latin American. Plaza de Mayo resembles a grand square in Madrid, and the ornate Teatro Colón would not be out of place in Vienna. But you’ll know you’re in South America by the leather shoes for sale on cobbled streets and impromptu parades of triumphant soccer fans. Limited-production wines, juicy steaks, and ice cream in countless flavors are among the old-world imports the city has perfected.

At 55 degrees latitude south, Ushuaia (pronounced oo-swy-ah) is closer to the South Pole than to Argentina's northern border with Bolivia. It is the capital and tourism base for Tierra del Fuego, the island at the southernmost tip of Argentina.Although its stark physical beauty is striking, Tierra del Fuego's historical allure is based more on its mythical past than on rugged reality. The island was inhabited for 6,000 years by Yámana, Haush, Selk'nam, and Alakaluf Indians. But in 1902 Argentina, eager to populate Patagonia to bolster its territorial claims, moved to initiate an Ushuaian penal colony, establishing the permanent settlement of its most southern territories and, by implication, everything in between.When the prison closed in 1947, Ushuaia had a population of about 3,000, made up mainly of former inmates and prison staff. Today the Indians of Darwin's "missing link" theory are long gone—wiped out by diseases brought by settlers and by indifference to their plight—and the 60,000 residents of Ushuaia are hitching their star to tourism.The city rightly (if perhaps too loudly) promotes itself as the southernmost city in the world (Puerto Williams, a few miles south on the Chilean side of the Beagle Channel, is a small town). You can make your way to the tourism office to get your clichéd, but oh-so-necessary, "Southernmost City in the World" passport stamp. Ushuaia feels like a frontier boomtown, at heart still a rugged, weather-beaten fishing village, but exhibiting the frayed edges of a city that quadrupled in size in the '70s and '80s and just keeps growing. Unpaved portions of Ruta 3, the last stretch of the Pan-American Highway, which connects Alaska to Tierra del Fuego, are finally being paved. The summer months (December through March) draw more than 120,000 visitors, and dozens of cruise ships. The city is trying to extend those visits with events like March's Marathon at the End of the World and by increasing the gamut of winter activities buoyed by the excellent snow conditions.A terrific trail winds through the town up to the Martial Glacier, where a ski lift can help cut down a steep kilometer of your journey. The chaotic and contradictory urban landscape includes a handful of luxury hotels amid the concrete of public housing projects. Scores of "sled houses" (wooden shacks) sit precariously on upright piers, ready for speedy displacement to a different site. But there are also many small, picturesque homes with tiny, carefully tended gardens. Many of the newer homes are built in a Swiss-chalet style, reinforcing the idea that this is a town into which tourism has breathed new life. At the same time, the weather-worn pastel colors that dominate the town's landscape remind you that Ushuaia was once just a tiny fishing village, snuggled at the end of the Earth.As you stand on the banks of the Canal Beagle (Beagle Channel) near Ushuaia, the spirit of the farthest corner of the world takes hold. What stands out is the light: at sundown the landscape is cast in a subdued, sensual tone; everything feels closer, softer, and more human in dimension despite the vastness of the setting. The snowcapped mountains reflect the setting sun back onto a stream rolling into the channel, as nearby peaks echo their image—on a windless day—in the still waters.Above the city rise the last mountains of the Andean Cordillera, and just south and west of Ushuaia they finally vanish into the often-stormy sea. Snow whitens the peaks well into summer. Nature is the principal attraction here, with trekking, fishing, horseback riding, wildlife spotting, and sailing among the most rewarding activities, especially in the Parque Nacional Tierra del Fuego (Tierra del Fuego National Park).

The remarkable beauty of the remote Falkland Islands can best be seen on New Island. The westernmost of the inhabited islands of the archipelago, it is a wildlife and nature reserve, and an environmental conservation group protects its many birds and animals. There are rookeries where Rockhopper Penguins and Blue-eyed Shags share the same nesting area. Black-browed Albatrosses can be seen going about their daily routines and it is easy to spot Upland Geese. More than 40 species of birds breed on the island. Near the landing site is ‘Barnard’s barn’ — a restored stone structure going back to the early 19th century. Lying in the sandy shallows in front of the barn is the wreck of Protector III, an old minesweeper used for seal hunting.

Located slightly northwest of West Falkland, West Point Island is used for sheep farming and nature observations. Peale’s dolphins and the distinctive black and white markings of the Commerson’s dolphin can usually be seen in the waters around West Point Island. Rolling moorland and steep cliffs make for great photographic opportunities, but the main attraction is the Devil’s Nose, a cliffside colony of Black-browed Albatrosses nesting side-by-side with feisty Rockhopper Penguins. Magellanic Penguins and Magellanic Cormorants can also be found on the island.

Saunders Island is the fourth-largest of the Falkland Islands in the western portion of the archipelago. The island’s topography is unusual, being made up of three peninsulas linked by narrow necks, and three big upland areas. Today the island is run as a sheep farm, but has historical importance as the location of the first British settlement in the Falklands. Saunders’ wildlife is also impressively varied. It is possible to see Gentoo and King Penguins in the open dune and sand-flat area, while Rockhopper Penguins (with the odd pair of Macaroni Penguins in between them), Imperial Shags and Black-browed Albatrosses frequent Mount Richards, the highest point on the island at 457 m (1500 feet). Other key bird species are the Black–throated Finch, Ruddy-headed Goose and Falkland Steamer Duck.

Tiny Stanley, capital of the Falklands, seems in many ways like a British village fallen out of the sky. Many homes are painted in bright colours, adding visual appeal to this distant outpost. Not far offshore, the wreck of the Lady Elizabeth, is one of the many vessels remaining as a silent testimonial to the region's frequent harsh weather conditions.The islands, also known by their Spanish name of Islas Malvinas, are home to arguably more tuxedo-clad inhabitants of the penguin variety than human residents. Various species, such as Gentoo, Magellanic and the more elusive King penguins, either live here permanently or use the Falklands as a stopover on their migration route. Darwin found the islands' flora and fauna fascinating - no doubt you will, too.
