Chorna (river) in the context of "Battle of the Chernaya"

Sevastopol Bay (Ukrainian: Севастопольська бухта, romanized: Sevastopolska bukhta; Russian: Севастопольская бухта, romanized: Sevastopol'skaya bukhta) is a city harbor that includes a series of smaller bays carved out along its shores. The bay of Sevastopol splits the city of Sevastopol into the Southern side and the Northern side. It serves as an extension of the Chorna River and stretches for 7.5 km (4.7 mi) which is the longest of them all.

The bay of Sevastopol stretches from the open sea eastward to the Inkerman Cave Monastery at the end, narrowing down and finishing at the mouth of the Chorna River. The bay forms the seaward approach to the city. Covering a large expanse of water, the harbor serves as a comfortable anchorage for a fleet. From the beginning of the 20th century it housed cruisers and ironclads.

The Baydar or Baydari valley sprawls for 16 km north-east in the Balaklava Raion of Sevastopol, Crimea. It is the source of the Chorna river and the location of the Chorna River Reservoir, Sevastopol's largest body of fresh water. Prehistoric menhir-statues still dot the landscape. A highway from Yalta to Sevastopol traverses the dale. The Baydar Pass connects the valley to the Black Sea coast. Most of the valley is protected as a national zakaznik, called the Baydar Nature Reserve.
