Cherni vrah

Cherni Vrah is the summit of Vitosha Mountain in Bulgaria. Rising to 2290 m, the peak is the fourth highest mountain summit in the country after Musala, Vihren, and Botev Vrah.

Cherni Vrah is bounded to the northwest by Torfeno Branishte which — like the extensive adjacent territory to the south — is a no-go drinking water catchment area. Several major stone rivers are situated in the peak's vicinity, occupying the upper courses of Vladayska and Boyanska Rivers to the north, and Struma River to the south.

The peak is part of the water divide between Black Sea and Mediterranean Sea, its northern slopes draining into Iskar River, and eventually into Danube River and Black Sea, and the southern slopes draining into Matnitsa River, flowing in turn into Struma River and Aegean Sea.
