Why this route stands out

A closer look at the journey

Buenos Aires

Passionate, and alive with an infectious crackling energy, the Argentine capital is a breathlessly romantic city, which blends old-world colonial architecture with a down-to-earth Latin American clamour. Famed for steamy tango interplays, and expertly seared steak slabs, a visit to Buenos Aires is a fiery fiesta for the senses. Parque Tres de Febrero is a 400-hectare oasis where 18,000 rose bushes bloom, and skyscrapers give way to still lakes and pretty paths of rollerblading locals. Mighty palm trees - that look like exploding fireworks - stand tall in Plaza de Mayo, the heart of this sprawling cosmopolitan capital of 48 barrios. The square has served as the stage for many fundamental events in this country’s history, and the location where the seeds of independence were sewn continues to serve as the city’s gathering point - and is a place for solidarity, rebellion and revolution. The presidential Casa Rosada’s salmon-hued Palatial Palace borders the plaza, while nearby Museum Nacional de Bellas Artes houses the largest collection of public art in Latin America. Teatro Colón, the opulent 1908 opera house, is one of the world’s finest venues - musical performance here take on an ethereal quality, with the exceptional acoustics transferring every quiver of bow, and tremor of vocal cord, to the audience in spine-tingling clarity. The gargantuan, precipitous terraces of Bombonera Stadium form another of Buenos Aires’s incredible venues, and a wall of noise emanates from it when Boca Juniors take to the field. Juicy steak and punchy Malbec flow in the city’s parrillas – steakhouses - while glitzy bars and thumping nightclubs welcome revellers late into the night. It’s not just the meat that sizzles here either - tango dancers fill milongas - dance halls - to strut passionately until the early hours. Sip steaming mate, the country’s national drink, shop in covered markets, and explore Cementerio de la Recoleta - a city of grand graves and intricate memorials honouring presidents, politicians and notable Argentine heroes from history.

Elephant Island

Promising thrilling adventure, legendary tales and immaculate Antarctic beauty, Elephant Island is perhaps Antarctica’s best-known location. The exploits of its early explorers have immortalised this harsh, monochrome island in the tomes of human history. Believed to take its name from the elephant seals that early explorers spotted lolling on its rocks, the volcanic island was not properly explored until 1916 - when Ernest Shackleton and his men were stricken by the weather and sought salvation on its shores. Their story of survival, stranded in this barren land, is one of humanity’s most evocative and inspiring accounts. Elephant Island is written deep into the legend of Antarctic exploration, and you’ll discover Shackleton’s tale for yourself as you arrive in the island’s icy realm. The remarkable, slowly flowing Endurance Glacier - which you’ll see on arrival here - takes its name from their ship, The Endurance. Visit the monument that stands to Shackleton, often surrounded by a migrating crowd of tiny gentoo penguins, at Point Wild - the spot where he and his 28 crew members camped for four and a half months of Antarctic winter. Eventually, Shackleton and a handful of courageous others sailed for South Georgia Island, before returning to secure the rescue of the remaining crew members. Aside from sailing amid breathtaking winter vistas, witnessing incredible fauna and feeling the sheer rush of an adventure to the unknown - one of the true joys of any Antarctic cruise is to follow in the footsteps of the brave explorers who first sought out the alluring nectar of these dangerous, evocative landscapes. If this will be your first-time visiting Antarctica, read our blog explaining how you can prepare for the exploits ahead.

Ushuaia, Argentina

Ushuaia, capital of Tierra del Fuego and the province’s main tourist hub, is located at the southern end of Isla Grande. Boasting a spectacular location, sandwiched between the mountains – including Cerro Martial and Mount Olivia – and the sea, Ushuaia extends down the hill towards the arm of land that surrounds the Bay, where the ship will stop during your MSC WorldCruise. The city is protected from the icy Southwest winds and occasional storms that occur in the Beagle Channel. Interesting excursions include the small islands in the middle of the channel in front of the city, with their colonies of seabirds, and the nearby Parque Nacional Tierra del Fuego. Ushuaia is the most populous and popular city in Tierra del Fuego, and depends largely on the thriving tourism industry, which capitalises on the beauty of the area’s natural landscapes. Overlooking the sea is the Antigua Casa de Gobierno, a late-20th century building that was originally the Governor's mansion before being used by the local government and then as a police station. It has been restored so as to return it to its original use, so you can get an idea of how the rich lived in Ushuaia at the dawn of the city. The Fin del Mundo Museum houses exhibitions that focus on the region’s history and wildlife, as well as the polychrome figurehead of the Duchess of Albany, an English ship wrecked on the eastern end of the island in 1883. The Parque Nacional Tierra del Fuego, 12 km west of Ushuaia, is 630 sq. km of rugged mountains, sinuous lakes, southern beech forests, marshy bogs, sub-Antarctic tundra and lush coasts. It extends along the border with Chile, from the Beagle Channel to Sierra Inju-Goiyin, north of the huge Lake Fagnano, which you can also visit on an MSC Cruise day trip, combined with Lake Escondido. This is just one of the fantastic destinations of our cruise around the world: MSC World Cruise 2020!
