The Nera River springs from the western part of Southern Carpathians, actually from the Semenic Mountains. At the point where River Nera River enters Anina Mountains, the water flow has carved out a breathtaking landscape, whose most attractive point is the Nera Gorges; the straits here are extremely spectacular, wild and rather hard to reach. The keys’ surrounding regions make a national park that was founded in 2004 and stretches along an area of about 37,000 hectares.
