The Jasmund National Park is a nature reserve on the Jasmund peninsula, in the northeast of Rügen island in Mecklenburg-Vorpommern, Germany. It is famous for containing the largest chalk cliffs in Germany, the Königsstuhl (German = "king's chair"). These cliffs are up to 161 m (528 ft) above the Baltic Sea. The beech forests behind the cliffs are also part of the national park.

Because of the special geological characteristics of the Jasmund National Park, it is home to many rare plants and animals. In the woods of the Stubnitz, behind the cliffs, there are numerous water-filled dells and hollows, most of which came into existence as ice-age dead-ice holes.[citation needed] A wide range of plants are found in this area, for example, black alder, European crab apple, wild service tree, yew and orchids (like the Cypripedium calceolus).
