The park features one of Europe's largest continuous gypsum karst areas.
It is home to the Heimkehle, one of the largest gypsum karst caves in Germany, featuring an underground lake.
The landscape contains over 100 known sinkholes, known locally as Erdfälle, caused by the dissolution of subterranean gypsum.
The park serves as a critical habitat for the endangered European wildcat.
It features the 'Karstwanderweg', a 200-kilometer long-distance trail spanning three federal states.
The park contains the ruins of the medieval Hohnstein Castle perched on a gypsum cliff.
The region includes rare calcareous grasslands that host specialized plant species not found in the surrounding forested Harz mountains.
The South Harz Nature Park is a 78,000-hectare protected landscape characterized by its unique gypsum karst geology and extensive cave systems. It serves as a transition zone between the Harz Mountains and the Thuringian Basin. The area is defined by massive anhydrite and gypsum deposits that create distinct sinkholes and steep cliffs. Visitors access a vast network of marked hiking trails, including sections of the Karstwanderweg (Karst Trail). The region is known for its diverse flora and fauna, including rare orchids and populations of wildcats. Educational programs and guided nature tours are managed from the administration office in Kyffhäuserland. It functions as both a recreational space and a center for geoconservation.

Carry a topographic map or GPS device, as mobile service can be inconsistent in deep sinkhole valleys.
Wear sturdy, waterproof hiking boots to handle uneven, rocky terrain and potentially muddy paths.
Check local weather forecasts specifically for the Harz foothills, as microclimates can cause rapid temperature drops.
Venturing into unmapped cave systems or off-trail areas, which poses significant risk of ground subsidence.
Stay on marked trails to protect fragile karst soil and plant life; dogs must be kept on a leash.
