Where Is Adalar Denizi (Aegean Sea)?
Adalar Denizi (“Sea of Islands”) — known today mostly as the Aegean Sea — is the arm of the Mediterranean that lies between Turkey and Greece. It stretches from the Dardanelles and the coasts of Thrace in the north to Crete in the south; its entire eastern shore belongs to Turkey (Çanakkale, Balıkesir, İzmir, Aydın, Muğla) and its western shore to Greece. It holds close to 3,000 islands and islets of all sizes — which is exactly where its historical Turkish name comes from.
What Is Adalar Denizi (Aegean Sea) Like?
In Ottoman geography and on the maps of the early Republic, this sea was called “Adalar Denizi” (in Ottoman Turkish Cezayir-i Bahr-i Sefid, “the islands of the Mediterranean”) — a descriptive name reflecting the density of its islands. The name “Aegean” comes from King Aegeus of Greek mythology (the king who threw himself into the sea believing his son Theseus was dead) and, with international usage from the mid-20th century onwards, also became common in Turkish. Although “Ege Denizi” (Aegean Sea) dominates in official and everyday language today, “Adalar Denizi” lives on in Turkish maritime tradition and in some institutional texts. Both names describe the same sea; one carries mythology, the other geography.

What Kind of Sea Is Adalar Denizi (Aegean Sea)?
Adalar Denizi is known for its deep blue colour, its clarity and the poyraz that blows steadily in summer (the etesian/meltem winds). Its northern part — including Edremit Bay — is a few degrees cooler and less salty than the south, giving it a refreshing character in the summer heat. The coves on the Turkish coast (the bay, between the Ayvalık islands) are sheltered from the wind and well suited to family boating.
Frequently Asked Questions
Are Adalar Denizi and the Aegean Sea the same sea?
Yes. “Adalar Denizi” is the historical Turkish name and “Ege Denizi” (Aegean Sea) the name of mythological origin that is common today; both refer to the same sea between Turkey and Greece.
Which Greek island is closest to Turkey?
Samos, about 1.7 km from the Dilek Peninsula, is the closest; Kastellorizo (Meis) is also only ~2 km from Kaş.
How do you get from Edremit Bay to the Greek islands?
The most practical route is via Ayvalık Port: regular ferries to Lesbos take about 1.5 hours. Sailings become more frequent in the summer season; a passport (and, depending on nationality, a visa or visa-on-arrival) is required.
Why is the Aegean so clear?
The deep basins of the Sea of Islands, its strong currents and short rivers carrying little sediment keep the water clear; the northerly poyraz wind also constantly renews the surface water.
