The Jasmund National Park (German: Nationalpark Jasmund) is a nature reserve in the Jasmund peninsula, in the northeast of Rügen island in Mecklenburg-Vorpommern, Germany. It is famous for containing the largest chalkcliffs in Germany, the so-called Königsstuhl (German = "king's chair"). These cliffs are up to 161 m high above the Baltic Sea. The beech forests behind the cliffs are also part of the national park.
The most majestic part of the cliffs is the 118-meter-high Königsstuhl (English: king's chair). One of the most scenic and best known of the chalk outcrops, the Wissower Klinken, collapsed into the Baltic Sea on February 24, 2005 in a landslide caused by spring-thaw weather conditions.
Since its creation in 1934, the Jasmund National Park has attracted hundreds of thousands of visitors annually. One of the main tasks of the National Park Authority is, therefore, to manage this flow of visitors in such a way as to ensure that the diverse habitats of the park remain largely undisturbed, whilst still allowing visitors an insight into the nature of the region. In March 2004, its visitor centre, the Königsstuhl National Park Centre, was opened.
