Suva Planina  is a mountain in southeastern Serbia. It lies between towns of Niška Banja on the northwest and Babušnica on the southeast, with a ridge branching towards Bela Palanka on north. Its earlier name was Kunovica. The highest peak is Trem  at 1,810 m, the second highest is Golemo Stražište at 1,714m, and there is also "Litica" at 1,683m  southeast side of the mountain. The name stems from the fact that there are only few springs in the whole mountain. Two biggest are Bojanine vode  and Rakoš česma . Traces of the Roman military road Via Militaris, connecting Singidunum  and Constantinople  are still visible across the mountain. As of 2010, Suva planina is undergoing a process of declaration of a special nature preserve. In last weekend in February there is a mountaineering event called "Zimski uspon na Trem" , that gathers over 600 mountaineers from all parts of the Balkans. It is also the biggest Balkan's mountain winter event. It started in 1997 and it is under the organization of Mountaineering club "Železničar" from Niš. The Divna Gorica range is known for the feral horses. They also roam to the other, higher parts of the mountain, above the altitude of 1,600 m . The slopes of this mountain are popular with skiing..
