Mount Ida is a lightly populated upland massif of about 700 km² located to the north of Edremit. A number of small villages in the region are connected by paths. Drainage is mainly to the south, into the Gulf of Edremit, also known as Edremit Bay, where the coast is rugged and is known as the Olive Riviera.. However, the Karamenderes River (the ancient Scamander) flows from the other side of Mount Ida to the west. Its valley under Kaz Dağları has been called the Vale of Troy by English speakers.
