In the region of Aisén, under endless skies, Cerro Castillo National Park stands as a sanctuary of natural beauty and historical legacy. Its mountains, crowned by the 2,318-meter-high (7,600 ft) Cerro Castillo, are guardians of a landscape shaped by glaciers and winds over millennia. Transformed into a National Park in 2017, after having been a National Reserve since 1970, Cerro Castillo is part of the Route of the Parks of Patagonia. This change reinforces the commitment to the conservation of its biodiversity, including the huemul, a critically endangered deer.

In its landscapes, turquoise lagoons such as Laguna Duff and the subantarctic forests of lenga and ñirre seem to stand still in time. Trails such as the Las Horquetas circuit offer physical challenges and a deep connection with the untamed essence of Patagonia. More than a destination, Cerro Castillo National Park is a living poem, an ode to the majesty of Aisén and a reminder of the importance of preserving this natural treasure. Its richness inspires respect and commitment to future generations.
