Huerquehue National Park is located in the foothills of the Andes, in the Valdivian temperate rainforest of the La Araucanía region in southern Chile. It lies 145 km southeast of Temuco and 33 km east of Pucón, between the Villarrica National Reserve to the west and the Hualalafquén National Reserve to the east.
The park encompasses 125 square kilometres of mountainous terrain east of Caburgua Lake, and has an elevation range of 720 to 2,000 m asl.The national park was created on June 9, 1967 in order to protect the area. However, its origins date back to 1912 and the creation of "Benjamín Vicuña Mackenna Park", also known as "Colico", which encompassed 265,000 Ha. Today, that land is divided into various different parks and reserves.
