Princes' Islands day trip guide from Istanbul

Why the Princes’ Islands are Istanbul’s best day trip

Nine islands sit in the Sea of Marmara about 20 km southeast of Istanbul. Four are inhabited; all are car-free by city ordinance. The result is a pace of life that feels genuinely different from the mainland — horse-drawn carriages, bicycles, pine forests, wooden Victorian mansions (called yalı), and fish restaurants where you eat watching Bosphorus ferries pass in the distance.

The Princes’ Islands (Prens Adaları in Turkish) were historically a place of exile — Byzantine princes, Ottoman dignitaries, Russian revolutionary Leon Trotsky (who lived on Büyükada 1929-1933). In the 19th century, wealthy Istanbul residents built summer retreats here, and many of those ornate wooden mansions survive. The largest island, Büyükada, is one of Turkey’s most distinctive places.

This is the one day trip from Istanbul that requires no flights, no early starts at 5 am, and no risk of feeling like you rushed through something important. It is also the most family-friendly excursion from the city.

Getting to the Princes’ Islands

Public ferry (IDO) — the standard route

The easiest option is the IDO (Istanbul Sea Buses) regular ferry service from Eminönü, on the European side near the Spice Bazaar. Ferries also depart from Kabataş (tram T1 terminus, near Dolmabahçe Palace).

• Eminönü to Büyükada: approximately 1 hour 45 minutes. Stops at Heybeliada and Burgaz Ada on the way.
• Kabataş to Büyükada: fast ferry takes about 45-60 minutes.
• Cost: Istanbulkart fare around 60-80 TRY each way (roughly 2 USD in 2026). Confirm current prices at ticket machines at the pier.

Ferries run from early morning (first departures around 7 am) to late evening. In summer, services are more frequent and boats more crowded — aim for the 8 am or 9 am departure to avoid weekend crowds.

Check the IDO website or app for real-time timetables before you go. In winter and shoulder season, services are reduced.

Guided tour with ferry included

Full-day Princes Islands tour with lunch from Istanbul includes the return ferry ticket, a guide, and lunch at a seafront restaurant on Büyükada. This makes sense if you prefer not to navigate the ferry timetables yourself or want historical context.

Getting around on the islands

On Büyükada:

• Bicycle hire: widespread near the ferry pier, around 200-300 TRY per day (6-8 USD). The island’s main circuit is about 8-9 km and manageable in 2-3 hours.
• Horse-drawn carriage (fayton): two routes cover the main viewpoints. Prices are posted at the carriage stands — expect around 400-700 TRY per carriage (12-20 USD) for the longer circuit. Agree the price before getting in.
• Walking: the ferry pier area and the main shopping street (İskele Meydanı) are easily walkable. The hilltop monasteries require about 30-40 minutes uphill on foot.
• Electric tuk-tuks: a newer addition to the island. Cheaper than fayton, less atmospheric.

What to do on Büyükada

The seafront and market area

The pier at Büyükada opens onto a lively waterfront with fish restaurants, tea houses, and souvenir stalls. The main street behind the pier is lined with bakeries, lokanta (local restaurants), and shops selling Turkish ceramics and jewellery. This area is most crowded between 11 am and 2 pm when day-trippers arrive.

Bike circuit of the island

The best way to experience Büyükada is on bicycle. The outer circuit passes pine forests, Ottoman-era military buildings (now private residences), old Greek Orthodox churches, and clifftop viewpoints over the Marmara. The east coast is quieter than the west. Allow 2-3 hours at a leisurely pace with stops.

Aya Yorgi Monastery

At the island’s highest point (Hill of Christ, Yüce Tepe), the Aya Yorgi (Saint George) Monastery dates to Byzantine times and remains active. The climb takes about 30-40 minutes on foot from the town, or a horse-drawn carriage can take you most of the way. The views from the hilltop across the Marmara to Istanbul and, on clear days, the Asian shore are exceptional. There is a small café up here.

A local tradition involves climbing the hill while unwinding a ball of wool, making a wish. You will see strings tied to trees on the path.

Splendid Palace Hotel terrace

The Splendid Palace Hotel (Splendid Otel in Turkish) is one of Büyükada’s most photographed buildings — an Edwardian pile with distinctive red domes, built in 1908. Non-guests can have tea on the terrace for a reasonable fee. The interior has been restored and the view from the front terrace is one of the best on the island.

Prinkipo Greek Orthodox Orphanage

The Great Orphanage (Büyük Prinkipo Yetimhanesi) is the largest wooden building in Europe, perched on a hill above the island’s second bay. It has been closed and derelict for decades — ownership disputes between the Turkish government and the Greek Orthodox Patriarchate have stalled restoration. You cannot enter, but the building viewed from below is extraordinary — seven storeys of decaying grandeur surrounded by pine trees. The situation may have changed by publication date; check current access status locally.

Visiting Heybeliada

Heybeliada (Halki in Greek) is the second-largest island, about 8 km northwest of Büyükada. The ferry from Istanbul stops here before continuing to Büyükada. If you want a quieter day away from the Büyükada crowds, Heybeliada is the better choice.

The island has fewer restaurants and facilities but more walking paths and a more local feel. The Halki Seminary (Heybeliada Ruhban Okulu) — once the main training school for Greek Orthodox clergy — was closed by the Turkish government in 1971 and remains closed, though its reopening has been periodically discussed. The building is visible from the ferry and from the island’s hilltops.

Cycling and walking options on Heybeliada are similar to Büyükada but with fewer tourists competing for space.

Practical information

What to bring

• Istanbulkart (topped up) or enough cash for ferry tickets
• Comfortable walking shoes or trainers for cycling
• Sun protection and water in summer
• A light layer even in summer — sea breezes can be cool on the ferry deck
• Cash for bike hire, fayton, and restaurants (cards are accepted at larger establishments but not all)

Costs summary (2026 estimates)

• Return ferry: 120-160 TRY (roughly 3-4 USD) on Istanbulkart
• Bike hire: 200-300 TRY per day (6-8 USD)
• Fayton (long circuit): 400-700 TRY per carriage (12-20 USD)
• Lunch (main course at a mid-range restaurant): 300-500 TRY (8-14 USD)
• Aya Yorgi Monastery: free entry

All prices are indicative for 2026 and subject to change given Turkey’s inflation environment.

When to go

• April-October: peak season. Ferries run frequently and all facilities are open. Summer (July-August) is hot and the main ferry can be very crowded on weekends.
• Shoulder season (April-May, September-October): best weather for cycling, fewer crowds.
• Winter (November-March): beautiful and quiet. Many restaurants close. Ferries still run but less frequently.

Avoiding the weekend rush

Istanbulites use the islands heavily on summer weekends. If your visit falls on a Saturday or Sunday in July or August, take an early ferry (7 or 8 am from Eminönü) and return before 3 pm, or after 6 pm. Midweek visits are significantly more relaxed.

Photographing the islands

Büyükada rewards patient photographers more than most Istanbul sights, mostly because the light changes character throughout the day and the car-free streets make composition easier than almost anywhere else in the city.

Morning (before 10am): The ferry pier and market street are at their emptiest and best for architectural shots of the wooden mansions without crowds in frame. Soft, even light works well for the pastel-painted yalı houses along the seafront road.

Midday: Harsh overhead light is the weakest window for photography, but it’s the best time for the bike circuit — the pine forest sections provide dappled shade and the clifftop viewpoints toward the Marmara are clear on cloudless days.

Late afternoon to sunset: The Aya Yorgi hilltop and the Splendid Palace terrace both face west-southwest, giving good light for the last two hours before sunset over the Marmara. This is also when the ferry back to Istanbul offers a classic shot of the island receding with the Istanbul skyline appearing on the horizon.

A few specific compositions worth planning for: the Splendid Palace’s red domes against a blue sky (best from the small park opposite, mid-morning); the horse-drawn faytons on the seafront road (best from a slightly elevated angle near the pier); and the abandoned Prinkipo Orphanage viewed from the path below, which photographs best in overcast conditions that soften the contrast between the decaying structure and the surrounding pines.

A brief guide to island etiquette

The Princes’ Islands operate by slightly different rules than central Istanbul, and knowing them in advance smooths the visit:

• Respect the no-cars rule fully — even electric maintenance vehicles move slowly and give right of way to cyclists and pedestrians; do not expect or ask for exceptions.
• Fayton drivers set fixed routes and prices — negotiate before boarding, not during or after the ride, and expect the price to be per carriage, not per person.
• Monastery and church etiquette — Aya Yorgi and the island’s other religious sites are active places of worship; modest dress (covered shoulders) is appreciated, particularly around the name-day pilgrimage in late April when the hill gets busy with worshippers as well as tourists.
• Beach and swimming spots are informal — Büyükada has small rocky coves rather than managed beaches; there are no lifeguards at most spots, so exercise the same caution you would at any unsupervised swimming location.
• Weekend etiquette: on summer weekends the islands genuinely belong to Istanbul residents on their day off. Visitors who time their trip for a weekday get a noticeably calmer, friendlier version of the same experience.

Combining with other day trips

The Princes’ Islands work well as a half-day if you have already explored Istanbul’s main sights. You can combine with a morning visit to the Spice Bazaar and lunch at the Eminönü pier before catching the afternoon ferry. Return in time for dinner in Karaköy or Kadıköy.

The history of Princes’ Islands

The nine islands have had various names and uses over the centuries. The Byzantine name was Prinkipo (“prince’s island”), referring to Büyükada, where exiled members of the imperial family were sent — safely away from Constantinople but close enough to be watched. The first Ecumenical Patriarch exiled here was Michael I Keroularios in 1058. This tradition of noble exile gave the archipelago its current collective name.

During the Ottoman period, the islands were largely neglected until the 19th century, when the introduction of steam ferries from Constantinople made them accessible as summer retreats. Greek and Jewish merchant families from Istanbul built the ornate wooden summer mansions (yalı) that still define the island’s architectural character. Many of these mansions — some in magnificent condition, others decaying — date from the 1870s to 1920s.

Leon Trotsky lived on Büyükada from 1929 to 1933, exiled from the Soviet Union. He completed the first three volumes of his History of the Russian Revolution here. The mansion where he lived, Yanaros Köşkü, is in the northeastern part of the island; it has changed hands many times and at various points has been proposed for conversion to a museum.

The islands’ Greek Orthodox community — once dominant — largely left following the Istanbul pogrom of September 1955 and subsequent restrictions on the non-Muslim community. The Ecumenical Patriarchate’s halki Seminary on Heybeliada, closed in 1971, remains a point of contention between the Turkish government and the Greek Orthodox community.

Island food guide

The Princes’ Islands have a distinctive food culture shaped by their Ottoman-Greek-Jewish heritage and their position in the Sea of Marmara.

Midye dolma (stuffed mussels): Mussels are stuffed with spiced rice (with currants, pine nuts, and cinnamon in the traditional style), closed, and sold from street vendors near ferry terminals. Approximately 10-15 TRY per piece (under 1 USD). Vendors add a squeeze of lemon. A Büyükada speciality.

Grilled fish (levrek, çipura, palamut): The Marmara seafood is excellent. Spring and autumn bring the best seasonal fish. Waterfront restaurants on Büyükada charge a premium for the view — walk 5 minutes from the ferry pier for slightly better prices.

Adalar lokum (island Turkish delight): Several shops on Büyükada sell locally made Turkish delight in varieties less commonly found on the mainland — rose, mastic (from Chios resin), and bergamot are among the island-specific flavours.

Meze plates: A shared meze spread at a Büyükada meyhane (tavern) — smoked aubergine, white bean salad, stuffed vine leaves, haydari (yogurt with herbs), and a cold fried calamari — with local rakı is one of Istanbul’s most pleasurable evening meals on a day-trip itinerary.

Practical tips for the ferry journey

The ferry itself is part of the Princes’ Islands experience. A few logistics worth knowing:

• Upper deck: On sunny days, the upper deck gives the best views of the Istanbul skyline receding as you sail, and the Marmara horizons ahead. In summer, this section fills fast — board early.
• Çay and simit: Vendors walk the ferry selling tea (çay, approximately 10-15 TRY / under 1 USD) and simit (sesame bread ring, approximately 15-20 TRY / under 1 USD). Both are ferry traditions.
• Ferry company app: The IDO app shows real-time ferry positions, which helps plan connections. Useful if the outbound timing is tight.
• Return ferry timing: On summer weekends, the last afternoon ferries back to Istanbul can be crowded. Aim for the 4-5 pm ferry or the 7-8 pm ferry to avoid the worst of the weekend return crowd.

What the Princes’ Islands are not

A few expectations worth calibrating:

• Not a swimming destination: Büyükada has some small rocky swimming spots, but the island is not primarily a beach destination. The closest good beach options from Istanbul are the Black Sea coast (see Şile and Ağva day trip from Istanbul guide) or the resorts south of the Marmara.
• Not a restaurant destination: The waterfront restaurants are fine but not exceptional. The experience here is more about the island atmosphere, the cycling, and the Victorian architecture than the food specifically.
• Not quiet in summer: Büyükada in July-August is a popular Istanbulite weekend destination. Midweek is significantly quieter than weekends.
