Watch birds on Keskimmäinen
Keskimmäinen is a lush lake surrounded by fairly large areas of fields. It is an important bird habitat and a nesting site for rare and near-threatened birds in North Savo. The greatest variety of birds on the lake is to be found in the migratory season, when many species rest and feed there. The lake has an approximately 60-hectare nature reserve, which is also part of the EU Natura network. On the northern shore of the lake, there is a bird watching tower, which is reached from the road Joensuuntie by duckboards. Cars can be left in the lay-by on the northern side of the road.
