Koli National Park

Koli National Park is a national park in the municipalities of Joensuu, Lieksa and Kontiolahti in the North Karelia region of Finland. It covers 30 square kilometres of forested hills on the western shore of Lake Pielinen. The park was established in 1991 and is currently governed by the Metsähallitus. It was originally governed by the Finnish Forest Research Institute, which is also called the Metla.

Koli National Park preserves the traditional agricultural heritage of the area. The park was once a pagan sacrificial site, and was later used for slash-and-burn agriculture. While fields in the park are no longer slashed and burned, hay is cut yearly and traditional Finnish breeds of cow and sheep graze in the meadows of Koli.
