The third-largest park in Chile, Alberto de Agostini is named for the Salesian priest and mountaineer who explored and photographed the area. De Agostini was moved by the majesty of the 22-mile Darwin Range, which reaches into the Pacific, sculpting deep fjords molded by the glaciers of Chile’s third stretch of icefields. Located roughly 800 nautical miles south of Punta Arenas, in Navarino, the park was declared a UNESCO Biosphere Reserve and is considered one of the 24 most pristine ecoregions on the planet. It is home to species including Marine Elephants as well as rich vegetation, spectacular glaciers like the Marinelli, and beautiful formations such as Monte Sarmiento.

“A wonderful view, difficult to describe, given the deep vastness of the horizon and the sublime grandeur of hundreds of peaks. These are the first human sightings of these solitudes of ice...”,

Alberto de Agostini


Virgin Coigüe forests grow on the hillsides, reaching down toward the waters of the fjords. These forests are sculpted by the region’s gale-force winds. Among the trees, you can also find Canelos, Ciprés de las Guaitecas (Pilgerodendron), Lengas, Ñirres, and an undergrowth made up of hundreds of different types of Mushrooms, Moss, and Lichen. Alberto de Agostini is also home to Magellanic Tundra, and Centellas, Orchids, Coicopihues, Chauras, and Anemones light up the parklands with their vivid colors in summer.


There are at least 108 different animal species in the park. The Marinelli Glacier––which, across many years, has molded the fjord that shares its name––is home to a colony of Marine Elephants, a species at risk of extinction. The park is also home to Leopard Seals, South American Fur Seals, Chungungos (Marine Otters), Whales, Dolphins, and 49 different land and marine bird species, including Albatross, Petrels, and Cormorants.


The Yámanas people were the world’s southernmost inhabitants, fishermen and gatherers who sailed the Beagle Channel to the north, the Brecknock Peninsula to the west, and Cape Horn to the south. They rowed in 16-foot-long canoes made from Coigüe bark, with sails made from the skin of sea lions. The watercraft were sturdy enough that they could light fires while aboard. The women dived in the cold waters, hunting for urchins and crabs. The Yámanas people also had a rich language: in 1933, the missionary Thomas Bridges published a Yámana-English dictionary, which contained more than 30,000 words. Orundellico, or Jemmy Button, was a Yáman man who sailed with Fitz Roy and Charles Darwin.
