The cliffs, c. 6 km long and up to 128 metres tall, are Denmark's highest, and support a unique set of natural habitats. Access to the narrow beach is via a flight of 500 steps from the parking area set within the beech forest behind the cliffs. The GeoCenter Møns Klint, a geological museum tracing the origins of Denmark and the formation of the cliffs opened there in May 2007. The combination of chalk in the subsoil with a dry local climate, and its agricultural use consisting primarily of cattle grazing, has created some of Denmark's richest meadowlands. The chalk was transported to Møn during the fourth, and most recent, major ice age.
