Salpausselkä UNESCO Global Geopark tells the story of the best-known geological entity of Finland. It is situated in the Lahti region in southern Finland and it consists of the area of six municipalities in Päijät-Häme: Lahti, Hollola, Heinola, Asikkala, Sysmä and Padasjoki.
The First and Second Salpausselkä are unique ice-marginal formations laid down by ancient meltwater streams at the end of the Ice Age. They reach across the entirety of southern Finland and are at their most spectacular in the area of Salpausselkä Geopark. Here they are joined to eskers of international value, such as the picturesque Kelvenne Island and Pulkkilanharju Esker in Päijänne National Park.
