Overview
The Argentine Sea, an arm of the Atlantic Ocean off Argentina's coast, is a vital waterway for cruises exploring the dramatic landscapes of Patagonia and voyages to Antarctica. This dynamic marine region offers a remarkable blend of vast, rugged coastline and unique wildlife.
Voyages here highlight Patagonia's natural wonders, including immense glaciers, national parks, and diverse marine and terrestrial fauna. From waddling penguins to breaching whales, a cruise in the Argentine Sea promises an adventurous journey through one of the planet's most untamed and captivating regions.
Visit Peninsula Valdés, a UNESCO World Heritage site near Puerto Madryn, renowned for its abundant marine wildlife. Depending on the season (especially June-December), observe Southern Right Whales calving and breeding. Year-round, you can see Magellanic penguins, sea lions, and elephant seals.
Tip: This is one of the best places in the world for wildlife viewing. Tours often include visits to the different colonies and whale watching excursions.
Arrive at Ushuaia, the southernmost city in the world and the capital of Tierra del Fuego. Explore this vibrant frontier town set against the backdrop of the Martial Mountains, visit the End of the World Museum, and soak in the unique atmosphere of this remote port, often the gateway to Antarctica.
Tip: Take the scenic End of the World Train into Tierra del Fuego National Park for a memorable experience.
From Ushuaia, venture into Tierra del Fuego National Park, Argentina's only national park with a marine coastline. Enjoy stunning landscapes of forests, lakes, and rugged coastline. Hike well-marked trails, observe native birds, and breathe in the pristine Patagonian air.
Tip: Many cruise excursions offer options for different hiking levels. Wear comfortable walking shoes suitable for varied terrain.
Experience a scenic cruise through the Beagle Channel, a strait in the Tierra del Fuego archipelago. Marvel at the dramatic landscapes, pass by remote islands, and look for marine wildlife such as sea lions, cormorants, and various seabirds, often with views of the famous Les Eclaireurs Lighthouse.
Tip: Boat trips are readily available from Ushuaia and offer fantastic photo opportunities.
Begin or end your cruise in Buenos Aires, Argentina's cosmopolitan capital. Explore its European-influenced architecture, vibrant neighborhoods like La Boca and Palermo, historical sites like Plaza de Mayo, and immerse yourself in the passionate world of Tango.
Tip: Allow extra days pre or post-cruise to truly experience this diverse city. Consider a tango show and dinner.
For many, a highlight is getting up close with penguins. Excursions from Ushuaia may offer boat trips to Martillo Island, home to large colonies of Magellanic and Gentoo penguins, providing incredible opportunities for observation.
Tip: Respect the guidelines for interacting with wildlife to minimize disturbance to the penguins in their natural habitat.
