Koli National Park (Kolin kansallispuisto) is a national park in the municipalities of Eno, Lieksa and Kontiolahti, Eastern Finland. It is located in the forested hills on the eastern shore of lake Pielinen, and was established in 1991. Contrary to the other national parks in Finland, Koli National Park is governed by Finnish Forest Research Institute Metla. Koli has lots to offer cultural heritage-wise. Former it was a sacrificial site. Later it was used for slash-and-burn agriculture. The aim of Koli National Park isn't to reserve wild nature but traditional agricultural heritage is cherished in Koli. Some fields are slashed, burnt and re-cultivated and hay is cut yearly. Traditional Finnish breeds of cows and sheep are grazing in the meadows of Koli.
The most well-known vantage point in the park is Ukko-Koli, with a grand view to the East, over the lake Pielinen. Near the top there's the Heritage Center Ukko and Hotel Koli. In the summer, two long scenery lifts are working in Koli. Nowadays there are two ski resorts in Koli area: Loma-Koli for families and Ukko-Koli for more advanced downhill skiing. There are three ski lifts and six ski slopes in Ukko-Koli. The highest vertical drop is 230 meters and ski slopes are 800–1,500 meters long.
