Comprising the largest bog of northwestern Europe, the park consists of two areas, De Weerribben and De Wieden, and has an area of roughly 100 square kilometres . The park was founded in 1982, but De Wieden was added only in 2009.
Large parts of the area were used for peat production till the Second World War. Since then a part of the area has been used for cane production.
