Parque Nacional Alerce Andino sits in the Los Lagos Region of Chile, roughly 46 km from Puerto Montt, and serves as the northern gateway to the Ruta de los Parques de la Patagonia.

Established in 1982, the park spans more than 39,000 hectares of temperate rainforest and shelters around 50 lakes and lagoons ringed by granite walls.

Its defining feature is the ancient alerce (Fitzroya cupressoides) tree, with specimens exceeding 3,000 years old covering more than half the park's surface. The park is accessed via two main sectors.

The Lenca sector entrance lies just off Route 7, about a kilometer past the Río Lenca bridge, then 7 km along a gravel road. Near the Río Lenca, a mirador overlooks the river and connects to a boardwalk with picnic tables.

The Chaicas sector, reached from the south, offers the hiker-only Camping Los Chucaos, located roughly 2. 5 km from the entrance.

Wildlife includes pudú and the endemic monito del monte, and the park is classified as part of the Temperate Rainforest Biosphere Reserve of the Southern Andes.
