Alerce Andino National Park is located in the Andes, in Los Lagos Region of Chile. This national park covers about 393 km². It is bounded by the Reloncavi Estuary on its east and south sides, and by the Reloncavi Sound to the west (excluding a coastal fringe of a few km). To its north lies Chapo Lake. The park contains about 50 lakes and natural ponds.
The centerpiece of this lush and mountainous protected area are the Fitzroya cupressoides (locally known as Alerce) forests, which consist of pure and mixed stands comprising a total surface of about 200 km². The park provides important habitat for species such as Pudu and Monito del Monte.
