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.

Puerto Madryn

Puerto Madryn, where you will stop on your MSC World Cruise, is on the shores of the beautiful and protected Nuevo Gulf. The city is the gateway to the incredible Ecocentro, east of the city, an ecological treasure of the Valdés Peninsula where you can discover the rich marine life in the area. The Welsh landed here for the first time in 1865, but development was slow until the arrival of the railway two decades later, when Puerto Madryn became the port for the villages in the lower Valley of the Chubut River. The Parque Histórico Punta Cuevas marks the first Welsh settlement in Patagonia with the Monumento al Indio Tehuelche, a statue that celebrates the centenary of the arrival of the Welsh and pays homage to the Tehuelche. From here you can enjoy breathtaking views of the Nuevo Golf at sunset, lit up by the lights of the city. Along the promontory lies Puerto Madryn’s most important attraction, the outstanding Ecocentre. This interactive museum promotes awareness and respect for marine ecosystems. You can take an MSC day trip to go dolphin and sea lion watching out at sea, or to visit the Valdés Peninsula and Punta Tombo. The Valdés Peninsula is one of the most important marine reserves in the world, recognised as a UNESCO World Heritage Site in 1999. Nothing can prepare you for the amazing richness of the marine environment that surrounds it – and in particular the southern right whales which migrate here every year to swim in the waters off the town of Puerto Pirámides – nor for the immense colonies of animals living on the Peninsula’s steep, crumbly cliffs. Punta Tombo is home to the continent's largest colonyof penguins; the noise produced by the black and white Magellanic penguins is deafening, but walking through this avian metropolis, surrounded by the strangest sounds and tottering birds is a unique experience. This is just one of the fantastic destinations of our cruise around the world: MSC World Cruise 2020!

Punta Arenas, Chile

As we head back towards land, a statue of fellow explorer Ferdinand Magellan greets us. Located on the western side of the Strait of Magellan, Punta Arenas is the capital of Chile's Magallanes Region and the bustling centre base for South Atlantic fishing boats and Antarctic research vessels. This busy port town is a melding of cultures from the English sheep ranchers to Portuguese sailors, all of which are a symbol of Chile's rich history. Punta Arenas' city centre features impressive mansions dating from the late 19th and early 20th centuries. In 1982, Isla Magdalena was declared a Chilean Natural Monument. Residing in the Magellan Straits, it serves as a bird sanctuary specifically to the Magellanic penguins, who share their nesting area with cormorants amongst other seabirds and sea lions. We explore the island together with our ship staff, and learn more about these naturally curious and untamed creatures. However, simply watching 150,000 burrowing penguins share chores with their lifelong mates is quite amazing. Each morning and afternoon, the fishing penguins return to shore to switch places with their mate who has been taking care of the young. These same penguins return every year between October and March to lay eggs and raise their young.
