Cherni Vrah (Bulgarian: Черни връх, "Black Peak") 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 (2925 m, Rila Mountain), Vihren (2914 m, Pirin Mountain), and Botev Vrah (2376 m, Balkan Range).Cherni Vrah is bounded to the northwest by Torfeno Branishte (Turf Nature Reserve) which — like the extensive adjacent territory to the south — is a no-go drinking water catchment area.

Malak Rezen (Bulgarian: Малък Резен / ‘Little Slice’) is a peak rising to 2,191 m in northeastern Vitosha Mountain in Bulgaria. The peak is situated 1.5 km northeast of the summit Cherni Vrah, and 1.3 km north by east of Golyam Rezen Peak, surmounting Stenata ski run and Aleko site to the north.Malak Rezen is accessible by the Romanski chair lift, and serves in turn as a convenient starting point for the three highest peaks of Vitosha Mountain — Cherni Vrah (2,290 m), Golyam Rezen (2,277 m), and Skoparnik (2,226 m).
