The Princes' Islands are located in the Sea of Marmara southeast of central Istanbul and form an archipelago that has long been a popular destination for day trips. During the Byzantine period, the islands were used as places of exile and seclusion, and later became a summer and residential area with notable historical heritage. Today, people come here for a calmer atmosphere, walks by the sea, and old island architecture.

The archipelago consists of nine islands, of which Buyukada, Heybeliada, Burgazada, and Kinaliada are the most frequently visited. They preserve wooden mansions, villas from the late 19th and early 20th centuries, religious buildings, and neighborhoods with low-rise houses. An important feature of the islands is limited car traffic, so people usually get around on foot, by bicycle, and by small electric vehicles.

For tourists, the Princes' Islands are appealing for their combination of sea views, a historic setting, and a more relaxed pace compared with the central districts of Istanbul. Visitors come here to walk along the waterfronts and inner streets, climb to viewpoints, explore old houses, and spend several hours away from the city's bustle. In the warm season, some islands have beach areas and swimming spots, and the main connection with the city is by ferry.
