Princes’ Islands in Istanbul

The Princes’ Islands in Istanbul are a small archipelago in the Sea of Marmara, made up of nine islands. During the Byzantine period, they were used as a place of exile for princes and emperors. Later, during the Ottoman era, they became a summer retreat.

Today, the Princes’ Islands are among the most famous day-trip destinations from Istanbul.

What Are the Princes’ Islands in Istanbul?

The Princes’ Islands in Istanbul are a group of small islands located in the Sea of Marmara. Administratively, they belong to Adalar Municipality within Istanbul Province.

Historically, the Byzantines used the islands as a place of exile for members of the ruling family and political opponents, especially princes and princesses who were seen as threats to the throne. This is where the name “Princes’ Islands” comes from.

After the Ottoman conquest of Istanbul in 1453, the islands continued to be used at times as a place of exile. However, they gradually became a summer resort, which gave them a distinctive architectural character.

Today, the Princes’ Islands are a peaceful tourist destination that combines history, old wooden houses, sea views, and a calm atmosphere. They are among the most requested trips in Istanbul travel programs.

Names of the Princes’ Islands in Istanbul

The Princes’ Islands archipelago consists of nine islands. Four of them are main and relatively large islands that receive most tourist activity, while the other five are smaller and mostly uninhabited or sparsely populated.

The main Princes’ Islands in Istanbul are:

Büyükada

Büyükada, meaning “Big Island,” is the largest, most famous, and most visited of the Princes’ Islands.

It includes the main harbor, pedestrian streets, historical wooden houses, mosques, churches, and monasteries. One of its most famous landmarks is the Aya Yorgi Monastery on the hilltop.

Heybeliada

Heybeliada is the second-largest island.

It is known for its relatively calm atmosphere, naval academy, beautiful summer houses, and streets suitable for walking and cycling.

Burgazada

Burgazada is a smaller and quieter island.

It is famous for the house of the Turkish writer Sait Faik, which is now a museum, as well as walking paths overlooking the sea and forests in a semi-rural atmosphere.

Kınalıada

Kınalıada is the smallest of the four main islands.

It is relatively close to the mainland and is known for its reddish soil and hills that offer beautiful views of the Sea of Marmara and the sunset.

In addition to these four islands, there are smaller islands such as Sedef Adası, Yassıada, Kaşık Adası, and others. However, they are less popular for tourism and are usually not included in traditional day-trip programs.

Where Are the Princes’ Islands Located in Istanbul?

The Princes’ Islands are located in the Sea of Marmara, southeast of Istanbul’s city center, mainly off the Asian-side coast near Kadıköy, Bostancı, Maltepe, and Kartal.

On clear days, the islands can be seen from several points along the coast.

The islands form one administrative district called Adalar. Their total area is estimated at around 11 to 16 square kilometers, making them one of the smallest districts of Istanbul in size, yet one of the most famous for tourism.

How to Get to the Princes’ Islands

The Princes’ Islands can be reached by ferry from several ports in Istanbul.

From the European side, ferries may depart from:

Kabataş
Eminönü
Beşiktaş

This depends on ferry companies and the season.

From the Asian side, ferries may depart from:

Kadıköy
Bostancı
Kartal

The regular ferry trip to Büyükada usually takes around 60 to 90 minutes, depending on the departure port and the number of stops at other islands.

Fast ferries can take less time.

A full-day trip often includes transportation from the hotel to the port, ferry tickets, a tour on the island, and return in the evening.

Things to Do on the Princes’ Islands in Istanbul

The Princes’ Islands are ideal for a one-day trip that combines the sea, nature, old architecture, and waterfront cafés.

Most travel programs focus on Büyükada, and sometimes include a short stop on another island.

Walk Through the Island Streets

Walking between wooden houses, small gardens, and quiet streets allows visitors to enjoy the mixed Ottoman and European architectural character of the islands.

Rent Bicycles or Electric Vehicles

After the traditional horse-drawn carriages were banned, bicycles and electric vehicles became popular ways to explore the farther parts of the islands.

It is always recommended to choose safe routes and follow local instructions.

Sit in Waterfront Cafés and Restaurants

Visitors can enjoy a fish meal or a light snack in restaurants overlooking the sea, with direct views of boats, the harbor, and the Marmara coast.

Swim in Summer

Some islands, especially Büyükada and Heybeliada, have private beaches or seaside clubs where visitors can swim during the summer season.

Visit Religious and Historical Landmarks

The islands include several religious and historical landmarks, such as Hamidiye Mosque in Büyükada, old churches, and Byzantine monasteries spread across the islands.

These sites add a cultural and historical dimension to the visit.

A good travel program can include free time on the island, with a clear return time to the ferry to keep the trip smooth and stress-free.

Important Tips for Visiting the Princes’ Islands

Try to leave Istanbul early to enjoy a longer day on the island and avoid port crowds around midday, especially in summer and on weekends.

Wear comfortable shoes, as most of the day will involve walking or cycling, and the island streets include both uphill and downhill paths.

Bring a light jacket, as the sea breeze can feel cooler than central Istanbul, especially early in the morning or in the evening.

Check ferry departure and return times carefully, or follow a clear tour schedule with set meeting and return times.

Do not throw waste on the beach or streets.

Respect local residents and the environment, as the islands depend heavily on responsible tourism to preserve their beauty.

Conclusion

The Princes’ Islands in Istanbul are not just one island, as some visitors may think. They are a complete archipelago of nine small islands that evolved from a place of exile for princes during the Byzantine era into one of the most beautiful leisure destinations for Istanbul residents and visitors today.

If you want to add a calm romantic or family-friendly experience to your Istanbul itinerary, make the Princes’ Islands a special day in your schedule.

A well-organized trip from the hotel to the ferry, then to the island and back, offers a comfortable and memorable sea experience in one of the most beautiful areas of the Sea of Marmara.
