Hiidenportti National Park

Hiidenportti National Park is a national park in Sotkamo in the Kainuu region of Finland. Hiidenportti National Park was established in 1982 to preserve the region's wilderness. A mosaic mix of mires and dry forests is typical landscape in this national park. The park covers 45 square kilometres.

Two thirds of the area is coniferous forest. The near-natural state forests are 100–150 years old on average. The last loggings were made in the beginning of the 20th century.

The most well-known attraction of the park is the Hiidenportti gulley with vertical cliffs.
