Bernardo O'Higgins National Park protects a remote area of southern Chile. It is currently the country's largest protected area, covering a vast area within the Aysén and Magallanes and Antártica Chilena regions, including part of the Southern Patagonian Ice Field.

The Bosques Templados Lluviosos de Los Andes Australes Biosphere Reserve comprises eight national protected areas in southern Chile. It hosts extraordinary biodiversity and is classified as one of Earth's largest and most ecologically intact forest remnants.

Cabo de Hornos Biosphere Reserve is located in the South American continent's extreme south, in southern Chile. It comprises marine areas, islands, fjords, channels, forests, and moorland. The core areas are Cabo de Hornos National Park and Alberto de Agostini National Park.

Cabo de Hornos National Park is the world's southernmost national park, 12 hours by boat from Puerto Williams in the southern headland of Tierra del Fuego in southern Chile, the only place in the world where the waters of the Pacific and Atlantic Oceans meet.

Cerro Castillo National Park is located in the Aysén Region of southern Chile, along the Carretera Austral. Named after the magnificent Cerro Castillo peak, its unique landscape contains hanging glaciers that form lagoons with bright turquoise waters.

The Chilean Andes and Argentine Andes form most of the border between Chile and Argentina, making up the highest section of the Andes range. The Dry Andes, Wet Andes, Patagonian Andes and Fuegian Andes are climatic and glaciological subdivisions.
