The magnificent Cerro Castillo peak lies 7,605 feet above Coyhaique and Río Ibáñez, and in the area surrounding it, you’ll find a trekking circuit that has been named one of the most beautiful in all Chile. The Lenga and Ñirre forests are home to Huemules (South Andean Deer) and it’s not uncommon to spot one near the Ibáñez park entrance, just next to the Carretera Austral. The hanging glaciers form lagoons with bright turquoise waters, giving even more color and life to a unique landscape that already captivates visitors from around the world.

Can’t Miss

  • See the impressive Cerro Castillo massif, which can be photographed from one of the lookout points along the Carretera Austral.
  • Do the trekking circuit that starts in Las Horquetas and travels around the massif to Laguna Cerro Castillo, finally ending at the Neozelandés campsite.
  • Visit Laguna Cerro Castillo and take in its intense turquoise color.
  • Look for Huemules (South Andean Deer), which can be spotted from the Carretera Austral.
  • Take photos of Laguna Chiguay in fall, when the Lenga forests surrounding it turn red.

"You shall love beauty, which is the shadow of a deity over the Universe.",

Gabriela Mistral


Deciduous forests make up much of the parkland. Highlights include the Lenga and Ñirre trees, though it’s also possible to find evergreen species like the Magellanic Coigüe. Notro, Calafate (Magellan Barberry), Chilco (Hardy Fuchsia), and Chaura are some of the native bush species, and beginning in November, you can see endemic wild orchids.


It’s common to see Huemules (South Andean Deer) along the route, and the park is also home to species such as the Puma, the Chingue (Molina’s Hog-Nosed Skunk), Foxes, and others. Condors and Black-Chested Buzzard Eagles fly over the peaks of the majestic Cerro Castillo, and the forest is home to birds like the Rayadito (Thorn-Tailed Rayadito), the Carpintero Negro (Magellanic Woodpecker), the Chucao, and the Churrín del Sur (Magellanic Tapaculo).


The Aonikenks, or Tehuelche people, were nomads who traveled the Patagonia by foot. They were expert hunters and used spears and bow and arrow to hunt Guanacos and Rheas. With the introduction of horses to the region during the 18th century, these peoples extended their routes through the southern steppe and made new hunting tools, such as boleadoras, a throwing weapon made of weights attached to cords.
