The Prince Islands (Turkish: Prens Adaları "Prince Islands," or locally more commonly called Princess Islands" Turkish: Prenses Adaları, also known as "Kızıl Adalar "Red Islands" or just Adalar as they are officially named; classical Greek: Πριγκήπων νήσοι Prinkēpōn nēsoi), are an archipelago off the coast of Istanbul, Turkey, in the Sea of Marmara. The islands also constitute the Adalar (literally Islands) district of Istanbul Province. The mayor of the Adalar (Islands) district is Atilla Aytaç (CHP).

Tourism and Transport:
During the summer months the Princes’ Islands are popular destinations for day trips from Istanbul. As there is no traffic on the Islands, the only transport being horse and cart, they are incredibly peaceful compared with the city of Istanbul. They are just a short ferry ride from Istanbul, with ferries departing from Bostancı, Kartal and Maltepe on the Asian side, and from Kabataş on the European side. Most ferries call in turn at the four largest of the nine islands: Kınalıada, Burgazada, Heybeliada and finally Büyükada.
Ferry and ship services are provided by 6 different companies. In spring and autumn the islands are quieter and more pleasant, although the sea can be rough in spring, autumn and winter, and the islands are sometimes cut off from the outside world when the ferry services are cancelled due to storms and high waves. During winter, with the addition of the biting cold and the strong winds and the resulting ferry cancellations, the islands become almost deserted. As for cultural tourism, Büyükada happens to have the first and only city museum in İstanbul, the Museum of the Princes' Islands in Aya Nikola Bay.
