The Jelašnička Gorge is part of the river valley of the Jelašnička River, created by the intense vertical cutting of its water flow into the limestone rock mass, the western branches of Suva Planina. It is located in the city municipality of Niška Banja, between the settlements of Jelašnica and Čuklenik. It is located 14 km east of Niš and 3 km from Niška Banja. It is about 2 km long and only 30 meters wide. It connects the Niska basin with the settlements and the tourist destination of Bojanine Voda on the northwestern slopes of Suva Mountain. Since 1995, the Jelasnica gorge has had the status of a nature park of the first category of protection, as a natural asset of the Republic of Serbia of exceptional importance.
