Seitseminen National Park is located on a watershed of western Finland in the central boreal forest zone. Some of the state-owned forests in Seitseminen have been under protection since the beginning of this century. The rural area surrounding the park is sparsely populated. Tampere, the nearest town, lies 80 km to the south of the park. Seitseminen National Park covers an area of 4550 ha. The forests cover 51%, the peatlands 45% and the cultural heritage landscapes 0,1% of the park. There are about thirty small lakes and pools in the park. Eskers, oriented north to south, are the geologically significant landforms.

The nature is barren and the number of species is limited. Both flora and fauna show characteristics typical to northern nature. Many regionally or nationally threatened species breed in the natural peatlands and the old forests of the park.
