Lake Päijänne is the second largest lake in Finland, and in the middle of its open waters you can find a treasure; Päijänne National Park, which consists of small islets and bigger islands with steep rocks or sandy eskers. It is situated in the southern part of the lake, where about fifty uninhabited islands and islets, and some inhabited ones belong to the National Park.
The park is most suitable for canoeing and boating, and almost all the areas of the park are only accessible by water.
