Gulf of Saros or Saros Bay (Turkish: Saros Körfezi) is a gulf north of the Dardanelles, Turkey. Ancient Greeks called it the Gulf of Melas (Ancient Greek: Μέλανας κόλπος, romanized: Mélanas kólpos).
The bay is 75 km (47 mi) long and 35 km (22 mi) wide. Far from industrialized areas and thanks to underwater currents, it is a popular summer recreation resort with sandy strands and crystal-clear sea. Scuba diving, windsurfing and fishing are the most practiced water sports here.
