The Baydar or Baydari valley sprawls for 16 km north-east in the Balaklava Raion of Sevastopol, Crimea. It is the source of the Chernaya River and the location of the Chernaya 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.
