Overview
Most İstanbullus refer to the Princes' Islands as 'The Islands' (Adalar). Lying 20km southeast of the city in the Sea of Marmara, the islands are a popular destination for a day escape from the city but are oppressively crowded between May and October, when visitors can number up to 50,000 per day on weekends. Five of the nine islands in the group are populated; most visitors head to the two largest, Büyükada and Heybeliada.
