Kuljunkari Island lies in the Bothnian Bay in northern Finland. If an island is defined as an area of land more than 20 square metres (220 sq ft) that is surrounded by water, the Bay of Bothnia has 4,001 islands. Many of the islands are uninhabited and in a natural state. In the winter the larger islands may be accessed via ice roads. Some of them are inhabited or have seasonal fishing villages used by people from the mainland
