Alberto de Agostini National Park is a protected area that was created on January 22, 1965, on land that was formerly part of the "Hollanda" forest reserve and "Hernando de Magallanes National Park". It covers 1460000ha and includes the Cordillera Darwin mountain range, which is the final land-based stretch of the Andes before it becomes a chain of mountains appearing as small islands that sink into the Pacific Ocean and the Beagle Channel. The park, along with Cabo de Hornos National Park, was designated a Biosphere Reserve by UNESCO in 2005. As part of the Magallanes Sub-Polar (or Sub-Antarctic) Evergreen Rainforest, UNESCO highlights the area’s "mosaic of contrasting ecosystems and unique and singular characteristics on a world level." Several tidewater glaciers and steep fjords can be found in the park. It also comprises the Gordon, Cook and Londonderry islands, as well as part of Hoste Island (excluding the Hardy Peninsula and other portions).
