Sićevo Gorge

 ravine, canyon / gorge, nature conservation park / area, invisible

In its Serbian part, the Nišava carved a composite valley with several depressions (Dimitrovgrad, Pirot (or Basara; Cyrillic: Басара), Bela Palanka and Niš). However, the most prominent geological feature the river formed is the Sićevo gorge (Sićevačka klisura; Cyrillic: Сићевачка клисура) between Bela Palanka and Niška Banja. The river is quite powerful in the gorge, which is used for two power stations ('Sićevo' and 'Ostrovica') used for electricity production, irrigation and fishery. The gorge is 17 km long, 350-400 m deep, in some parts developing canyon like-structures (like inverse valley slopes at Gradiški kanjon; Cyrillic: Градишки кањон). The gorge itself carved through the Kunovica plateau between the southern slopes of the Mountains of Svrljig and the mountain of Suva Planina, and the surrounding areas are known for their high-quality vineyards. There is also a huge quarry in the gorge ('Ostrovica'), where six villages are located, the largest one being Sićevo that gives the name to the whole gorge.
