Princes Islands Day Trip from Istanbul: Ferry, Büyükada Plan and Guided Tour

A Princes Islands day trip from Istanbul needs a full day, not an afternoon: the public ferry takes about 75 to 90 minutes from the European side to Büyükada, the largest island, and most visitors want four or five hours on land before the late-afternoon boat back. You can do it alone with an Istanbulkart for very little money, or book a guided day. Our Princes' Islands full-day tour runs about 8 hours, includes hotel pickup, round-trip ferry tickets and lunch, and costs from $90 per person. It sits with our other day tours from Istanbul if you are comparing options for tomorrow.

This page is for two kinds of reader: people already in the city who want a sea day away from the Old City crowds, and people planning a week in Istanbul who wonder whether the islands deserve one of their days. The short answer is yes, on a dry day between April and October, and less obviously in winter.

Which Princes Island should you visit on a day trip?

There are nine islands in the group, and four of them take regular passenger ferries: Kınalıada, Burgazada, Heybeliada and Büyükada, in that order as you sail out. For a first visit, Büyükada is the sensible choice. It has the most to see, the widest choice of places to eat, the hill monastery of Aya Yorgi, and streets of wooden summer mansions built by Greek, Armenian, Jewish and Ottoman families in the nineteenth and early twentieth centuries.

Heybeliada is quieter and greener, with the old naval school by the pier and the hilltop Halki Seminary, the Greek Orthodox theological school that has been closed since 1971. Burgazada is small and residential; Kınalıada, the closest, is the barest and the least visited by foreigners.

A common mistake is to try to "do" three islands in one day. The ferry timetable does not really allow it without rushing. Pick Büyükada, add Heybeliada only if you start on the first boats, and keep the smaller two for a repeat visit.

How do you get to the Princes Islands by ferry?

Most visitors take the municipal Şehir Hatları ferry from Kabataş, the tram terminus below Dolmabahçe Palace. The crossing to Büyükada takes about 75 to 90 minutes depending on the boat and the number of stops. From the Asian side, ferries leave from Kadıköy, and the shortest crossing is from Bostancı, at around 50 minutes. You pay with an Istanbulkart; contactless bank cards are not accepted at most island ferry gates.

Fares on the island line are higher than on the cross-Bosphorus ferries because visitors pay the full rate without the residents' Adakart. On the 2026 tariff that was roughly 140 TL each way from the European side and around 85 TL from Kadıköy or Bostancı, according to timetable sites that list the municipal fares. Check the Şehir Hatları app before you go, because Istanbul's transport fares rise more than once a year.

The ferries are crowded on summer weekends, especially Saturday mornings from Kabataş, and the return boats around 18:00 can be standing-room only. On the way out, sit on the right-hand side for the view back to the Old City skyline and the Asian shore. Our step-by-step guide to the Princes Islands ferry from Kabataş has the stops and times in more detail.

A simple Büyükada plan for one day

This is the order our guides use when they take a group to Büyükada, and it works just as well for people going alone:

• 09:00–10:30 – ferry from Kabataş; coffee on the upper deck.
• 10:30 – land at Büyükada pier, walk past the clock tower square and up Çankaya Street, where the largest wooden mansions stand.
• 11:15 – electric shuttle or bicycle to Luna Park square, the base of the hill, then the walk up to Aya Yorgi.
• 13:00 – lunch, either at the restaurant at the top of the hill or back near the pier.
• 14:30 – the Greek Orphanage viewpoint, then free time by the sea.
• 16:30–17:00 – ferry back, arriving at Kabataş around 18:00 to 18:30.

The plan has slack in it on purpose. The shuttle queue at the pier can take 30 minutes on a busy day, and nobody enjoys running for the last good ferry. If you would rather not organise any of it, our Istanbul tours page lists the guided island day next to the city tours, so you can compare prices on one screen.

What to see on Büyükada: Aya Yorgi, the orphanage and the mansions

Aya Yorgi, the Monastery of St George, sits on Yücetepe, the higher of the island's two hills, at a little over 200 metres. The last stretch of the climb is a steep cobbled path with little shade; allow 30 to 45 minutes from the bottom and take water. The church itself is small. Most people go up for the view over the Sea of Marmara and the other islands, and for the custom of tying a thread on the way up and making a wish. Around 23 April, St George's feast, the hill is packed with pilgrims of several faiths, and queues for the shuttles stretch along the street.

The Prinkipo Greek Orphanage on the other hill is one of the largest wooden buildings in Europe. It was built as a hotel at the end of the nineteenth century, later housed orphans, and has stood empty for decades; you see it from outside, behind a fence. Below it, the lanes of Nizam and Maden hold the best mansions, many with gardens full of bougainvillea in summer. Leon Trotsky lived on the island in exile from 1929 to 1933, and his house, now a ruin, is a short walk from the pier.

There is also the small Adalar Museum, which tells the islands' social history and is worth half an hour if it is raining.

Getting around the island without cars

Private cars are banned on the islands. The horse-drawn phaetons that appear in older photos and guidebooks were withdrawn in 2020, and the municipality replaced them with small electric shuttles that run set routes from the pier square. They are cheap and useful for the climb to Luna Park, but they fill quickly on weekends.

The other options are walking and cycling. Bicycle hire shops line the streets behind the pier; a full loop of Büyükada is roughly 12 kilometres, with two long climbs, so an e-bike is worth the extra money if you are not a regular cyclist. Walking is pleasant in spring and autumn and hard work in July and August, when the afternoon heat on the hill roads is real.

Our group day includes the ferry, the assistant and lunch, but not bicycle hire or the electric shuttle, which you pay on the spot. That is stated on the tour page, and it is the same on most competitors' island tours.

Swimming, beaches and when the islands are at their best

The islands are a summer place for Istanbul families, and the water is clean enough that people swim from June to September. Büyükada has managed beach clubs with sunbeds, reached by shuttle or a long walk to the south side; Heybeliada has smaller coves. The Marmara is cold until June, and the beach clubs close by early October.

The best months for a day trip are May, June, September and early October: warm enough to sit outside, cool enough to walk the hill, and quieter than the school holidays. July and August are hot and crowded on weekends. In winter the ferries still run and the islands are almost empty, which some people love; many restaurants close, the hill path can be muddy, and a grey day on the water is not what most visitors picture.

If you are in Istanbul between November and March, a Bosphorus cruise or a city day may be the better use of your time, and the islands can wait for a sunny week.

Going alone or booking a guided island tour

Doing the islands independently is easy and cheap if you are comfortable with the Istanbulkart, the ferry piers and finding lunch on your own. A guided day makes sense when you have little time, are travelling with older parents or children, or simply do not want to deal with the Kabataş crowds. Here is how the two compare:

Prices vary by season and group size, so ask us for the current price for your date. Pickup times start from 08:00, with 09:00 the usual choice, and you can book now and pay later on the tour page. If you would rather have a car waiting at your hotel, read how our Istanbul tours with hotel pickup work.

Combining the islands with the rest of your Istanbul days

On a four- or five-day visit, the islands fit best on day three or four, after you have seen Hagia Sophia, Topkapı and the Grand Bazaar. Avoid Sunday if you can: weekend crowds on the ferries are heavier, and Monday and Tuesday are often calmer. A good pairing is an island day followed by an evening Bosphorus dinner cruise, since you are already in sea mode and back in the city by 18:30.

If the weather turns, swap the islands for one of our private Istanbul tours in the city and keep the ferry for another day. For longer stays, our list of Istanbul day trips compares the islands with Bursa, Şile, Sapanca and Gallipoli by travel time and who each trip suits. And if you want a fixed price for the whole stay, the Istanbul tour packages can include an island day with hotel and transfers. To check today's availability, message us on WhatsApp from any of our day tours pages and we will confirm pickup for tomorrow if seats are left.
