Embarking into the Unknown: Tierra del Fuego & Agostini National Park with Cruceros Australis

Today we board the M/V Stella Australis. After a welcoming toast and introduction of captain and crew, the ship departs for one of the remotest corners of planet Earth. During the night we cross the Strait of Magellan and enter the labyrinth of channels that define the southern extreme of Patagonia. The twinkling lights of Punta Arenas gradually fade into the distance as we enter the Whiteside Canal between Darwin Island and Isla Grande de Tierra del Fuego!

Boarding the Stella Australis

For the next three days we explore, a little-known protected area in the very south of Chile, the Alberto de Agostini National Park: the third largest in the whole country, covering an area of 5,637-sq. miles (14,600-sq. km). It takes its name from the Italian priest of the Salesians of Don Bosco order, Father Alberto María de Agostini, who drew up maps, took valuable photographs of the Magallanes region and worked alongside the local indigenous people.

Rainbow seen from our cabin our first morning

A region characterized by labyrinthine channels, plunging glaciers and pristine evergreen rainforests, it is only accessible by boat and is considered to be one of the most untouched parts of Patagonia.

Hidden bays await at dawn

The park marks the final point of the Andes Mountains: the longest continental mountain chain in the world. Spanning the entire length of South America, they start in Venezuela in the north and cover 4,300-miles (7,000 km) before they finally plunge into the ocean here in the Alberto de Agostini National Park.

Hiking among glaciers and misty peaks

At this point, they are known as the Cordillera Darwin (or Darwin Mountains) and they are so inaccessible that they were only first fully crossed in 2011 by a French expedition team. Mount Darwin, one of the highest peaks in this mountain range, acquired the name in honor of Naturalist Charles Darwin who was passing through the region as part of his five-year voyage on the HMS Beagle.

Hiking in remote forests

The most famous of the Alberto de Agostini National Park’s glaciers is the tidewater Marinelli Glacier, which spills from the Darwin Mountains and the Darwin Ice Sheet into Ainsworth Bay. Although it is currently retreating, this stunning glacier can be viewed from trails traversing the land around the bay.

Glaciers can be seen at every turn

Glacier Alley, a passage through the Chilean fjords lined by a series of impressive tidewater glaciers, is also located in the park. Named after European countries (including Spain, France, Holland, Germany and Italy), these glaciers flow from the Darwin Mountains into the ocean. The ‘calving’ of ice from their termini – viewed from the safety of a cruise ship – is an unforgettable sight.

In front of the Brooke’s Glacier

The Águila (“Eagle”) Glacier flanks the Agostini Fjord (or Agostini Sound) and the scenery in this part of the national park has been compared with the landscapes of Tierra del Fuego National Park. To arrive at the glacier, a Zodiac boat must be landed on shore; visitors can walk close to the foot of the glacier which hangs above an aquamarine, glacial meltwater lagoon.

In 2005, the Alberto de Agostini National Park was designated a UNESCO Biosphere Reserve thanks to the singular characteristics of its ecosystems. One of the main features of the park which merited its inclusion in the UNESCO list is the subpolar Magellanic forest found here and which began to grow around 10,000 years ago when the glaciers formerly covering the area began their retreat.

Get up close and personal with icebergs

These Magellanic forests share plant families with temperate forest ecoregions in New Zealand and Australia, but the Alberto de Agostini National Park’s colder climate makes it less rich in plant life than the milder Valdivian forests which are found further north in Chile.

The colors are truly impressive

The fauna here is also impressive, with beavers, elephant seal colonies, the southern pudú (the world’s smallest deer) and the endangered southern river otter making up some of the most interesting wildlife species. Andean condors can sometimes be spied circling above land.

The only way to gain access to this fragile environment is via cruise ship. Tours allow close interaction with an incredible national park which marks one of the last uninhabited places remaining on Earth!
