It is characterized by great diversity of species and the notorious endemism of their wildlife, as the Toad's bar. One of its most important attractions is the Cordillera de Nahuelbuta, which gives the place a unique landscape.
Created in 1939, this park is situated in the pre-Andean plain of Nahuelbuta, west of Angol, in the Región de la Araucanía.
The mountains create the ideal conditions for the araucaria to grow. This tree, which is tipically found in the pre-Andean and Andean mountain chain, can also be found here, near the coast, with some specimens being around 2 thousand years old.
In the park, which name means "big tiger" in Mapudungun, there are coigües, robles, lengas and insectivore plant. Foxes, black woodpeckers, chucaos, and churrines are only some of the species you might find here. The hills here do not exceed the 1,600 mts (5,248 ft), the highest being Piedra El Águila, from which you can see the sea, the central valley, and the Andean volcanoes.
The park has camping and picnic areas as well as marked trails for exploration.
