Istanbul Islands: A Guide to the Princes' Islands

Escaping the City to the Sea of Marmara

Just off Istanbul's Asian shore, the Princes' Islands — known locally as the Adalar — offer one of the easiest escapes from the city's pace. The archipelago counts nine islands in all, but most day-trippers focus on four: Buyukada, Heybeliada, Burgazada and Kinaliada, with smaller spots like Sedef and Tavsan rewarding the more adventurous. Once a place of imperial exile, the islands today are a leafy retreat dotted with wooden mansions, monasteries and seaside cafes that span the Byzantine and Ottoman eras.

Getting there is half the pleasure. Ferries depart throughout the day from Kabatas, Eminonu and Bostanci, and the crossing serves up sweeping views of the Sea of Marmara and the receding city skyline. A full-day ferry ticket gives you the flexibility to hop between islands at your own rhythm.

What to See on Each Island

The defining feature of the islands is what they lack: cars. With private motor vehicles banned, you explore by bicycle, electric cart or simply on foot, and bike rentals are easy to find near the piers. Each island has its own character. Buyukada, the largest and busiest, is famous for its Ottoman-era mansions, pine forests and walking trails, crowned by the Aya Yorgi church and monastery on its highest point.

Heybeliada draws visitors with the historic Halki Seminary and the Naval Cadet School, plus shaded trails and quiet picnic spots. Burgazada is the artists' island, home to the hilltop Christos Monastery and a lively community of galleries and cultural events. Kinaliada, with its distinctive reddish soil and rustic Armenian and Greek heritage, is the closest to the mainland and a favorite for a quick swim.

Planning Your Visit

Spring and summer are the prime seasons, bringing the most pleasant weather, the widest ferry schedules and a calendar of music festivals and art exhibitions. Because the islands are popular with locals too, it pays to arrive at the terminals early, especially on weekends when crowds peak.

A few practical notes make the day smoother. Carry cash, since card facilities can be limited away from the main streets. Pack sunscreen, a hat and comfortable shoes for the hills and cobbled lanes. There are no entrance fees to the islands themselves — you only pay for the ferry — and if you plan to stay overnight during high season, book your accommodation well ahead. Above all, check the return ferry times before you settle in for that last seaside meal.
