[3] Puyehue National Park forms part of the Reserve of Temperate Rainy Forest Biospheres of the Southern Andes.

Anticura area features the Puyehue volcano, the El Puma lookout point, the Cordón Caulle and hot springs, a volcanic area, and a strawberry field, called the Pampa de Frutilla, the Salto de la Princesa, a waterfall of an inlet of the Golgol river, and an 800-year-old forest of coigüe trees, as well as recreational trails.

And finally, the Antillanca area of Puyehue National Park has a ski center and a good hotel open all year round.

Hiking, trekking, fishing, fauna and flora observation, swimming (heated pool), photography, climbing, excursions, horseback riding, snowboarding, mountain bike riding, downhill skiing, cross country skiing and bird watching are the activities that can be practised in the park.

[8] Its flora in the lower parts is that one of Valdivian temperate rain forest and is similar to that of its southern neighbor, the Vicente Pérez Rosales National Park.

Species of trees include coigüe (Nothofagus dombeyi) and the common ulmo (Eucryphia cordifolia), olivillo (Aextoxicon punctatum) and tineo (Weinmannia trichosperma).

At higher altitude there are coigüe woods with tepa (Laureliopsis philippiana) and mañío (Saxegothaea conspicua), which later became the dominant species.

Mammals in the Puyehue National Park are the puma, gray fox (pseudalopex griseus), the quique (galictis cuja) or ferret, the coypu (Myocastor coypus), the güiña (Felis guigna) or wild cat and the chingue (Conepatus chinga), skunks and vizcachas.

[7] The park is also a birdwatching destination with sightings of the torrent duck (pato correntino), the Magellanic woodpecker (carpintero negro), the Chilean pigeon (torcaza), the hued-hued (huet-huet), the Andean condor, the great grebe (huala), the Southern house wren (chercán) and the buff-necked ibis (bandurria).
