The park contains 482 km2 (186 sq mi) of rugged mountains and unspoiled Valdivian temperate rain forests.

The aforesaid lakes are characterized by distinctive blue and green hues, due to rock flour suspended in their waters and give to the river its milky appearance.

Among them are the cougar, kodkod, lesser grison, chilla fox, American mink, coypu, pudú and Chilean huemul.

[4] The park is administered by CONAF in the city of Hornopirén at the central square and all trips to the forest begin here.

Then there is another 7 km on a bumpy gravel road through private land in order to reach the park entrance.

There are two bus companies that run between Puerto Montt and Hornopirén National Park.

It is on the southwest side of Pinto Concha lake and provides information to tourists in the summer months.

The park is closed to the public between July and November because snow and ice over a meter thick accumulates in the recreation area.
