Located about 10 km east of Niš, Jelašnica Gorge is a protected natural area shaped by the erosive power of the Jelašnica River. This 1.5 km-long limestone gorge is characterized by cliffs, rugged rock formations, and striking karst features, including natural windows, overhangs, and cavities. Among the most remarkable formations are the Kulina and St. Ilija rock windows, which contribute to the gorge’s dramatic landscape.

Recognized for its rich biodiversity, Jelašnica Gorge is home to numerous endemic and relict plant species. Notably, it is one of the few locations in the Balkans where the Tertiary relicts Ramonda serbica and Ramonda nathaliae occur in sympatry, forming the Ramondetum nathaliae-serbicae plant community. In addition, the area is home to Parietaria serbica, as well as a variety of regional endemics, including 39 Moesian, 20 Balkan, and 6 Illyrian endemic and subendemic species.

Due to its extraordinary geological and ecological significance, Jelašnica Gorge is designated as a Category I protected area and is subject to second-degree protection. Covering an area of 115.73 ha, it has been under formal protection since 1995, with "Srbijašume" Public Enterprise serving as its managing authority.
