It spreads on the surface between the two rivers, Juzna Morava and its influent, Nisava. The rivers run through wide and fertile plains and impervious gorges, which gives a  specific natural feature to this region.  Through this part of Serbia , go the most important roads of the Balkans that lead towards the East and the South, towards Bulgaria and Greece. The cities of this region, although lying in the valleys, have their own mountains, among which the most impressive is Suva planina above Nis. Besides Nis, which is the center of this region, the other important city is Pirot, on the road from Constantinople to Belgrade, which existed even in the Roman times. It is famous for the unique examples of Pirot’s carpets, and Poganovo and Sukovo monasteries.

On the Veternica river, not far from its confluence into Juzna Morava, there is situated Leskovac, a town protected by Radan, Pasjaca and Kukavica mountains. Near Leskovac, at the exit of the town Lebane, there are located the remains of the Late Antique city Justiniana Prima/ Empress’ city, which inevitably must be visited, as well as the canyon of the Vucjanka river at the foot of Kukavica mountain. In the vicinity of Leskovac, in the south-east corner of Serbia, there is located Vlasina lake, with its floating isles, the main features of this lake. It is surrounded by the mountain tops, ravines and water springs, rivulettes  with their cascades, specific flora and fauna, old churches and monasteries, and remote villages. The most southern town in Serbia is Vranje which preserved many monuments from the Ottoman epoch and the spirit of the past. Along the very border with Macedonia, in the valley of the Pcinja river, there is situated Prohor Pcinjski monastery, consecrated to the South Slav saint, Prohor. In the proximity of the monastery, on the very border with Macedonia, there spreads Dukat mountain, completely forgotten, pristine part of Serbia. From Nis to Kosovo, lies Toplica region with the towns of Prokuplje and Kursumilja in its heart. Prokuplje developed at the place of antique Hameum, and it was named after St. Procopius’ temple from X century  located in the downtown which treasures the relics of this saint, as well as the hand of St. George. When you head from Prokuplje to Kursumlija, you cannot miss Plocnik- the archaeological site of Vinca culture, representing a complex of settlements from the early Stone Age. It was the oldest metallurgy center  of the time, and recently there has started the reconstruction of the neolithic village, and one of the ideas is to connect the site with the tourist train with Prokuplje, Kursumilja and Devil’s Town. The road moves on to Kursumlija, a medieval capital of Stefan Nemanja who built his first churches here: St. Nicholas  monastery and the Holy Virgin church. In the surroundings, there are located beautiful spas-Lukovska and Prolom, as well as the impressive Devil’s Town.  This is a rare natural phenomenon comprised of 22 stone figures, created by patient and long-term operation of nature. There exist similar phenomena in the world, but in Devil’s Town the figures are larger and more stable; and therefore, it’s the most famous natural monument attractive and interesting to many visitors from around the globe. They are located on Radan mountain, and they can be reached over Kursumlija and Bojnik, but the easiest and the most inspiring way is by hiking from Lebane.
