Between Angol and the Pacific, the coast range rises to 1550m within the 68-sq-km Parque Nacional Nahuelbuta. This is one of the last non-Andean refuges of araucarias (monkey-puzzle trees), the arboreal equivalent of fireworks. In summer other interesting plant life includes 16 orchid varieties and two carnivorous plant species. Various species of Nothofagus (southern beech) are common here, and the Magellanic woodpeckers that typically inhabit them make for great bird-watching. Rare mammals such as pumas, Darwin's fox and the miniature Chilean deer known as the pudú also live in the park. According to some, it's a prime location for UFO-spotting too.
The dirt road between Angol and Cañete runs through the park. Conaf maintains the park headquarters and information center at Pehuenco, roughly halfway between the two park entrances, which are sometimes staffed by rangers. The area enjoys warm, dry summers, but is usually snow-covered during winter.
