The Princes’ Islands from Istanbul: The Slow Ferry, Car-Free Lanes, and the Sunday Crush

Nine islands in the Marmara where Istanbul goes to exhale: no cars, pine hills, and a ferry ride that is half the point.

The short version

• Şehir Hatları ferries run from Kabataş, Eminönü, and Kadıköy, calling at the four main islands — about 90 minutes to Büyükada, paid with an Istanbulkart tap; times at sehirhatlari.istanbul.
• The islands are car-free. Electric minibuses and bicycles replaced the horse carriages; walking covers Büyükada’s center on its own.
• Büyükada is the headline island: Ottoman-era wooden mansions under pine, a clocktower square, and rental bikes for the shore loop.
• The climb to Aya Yorgi — the Greek monastery of St. George on the island’s highest hill — takes a steep 30 minutes and pays out the whole Marmara.
• Heybeliada, one stop earlier, is the quieter version: same pines and mansions, half the day-trippers.
• Swim clubs and platforms open around the shores in summer; a fish lunch by the Büyükada pier is the standard halftime.

Serious Day Tour Man saysOn summer Sundays half of Istanbul rides out with you and the evening ferries home are the crush. Go midweek if you can; if you cannot, take the first boat out, an early boat back, and check the last sailing at sehirhatlari.istanbul the moment you land.About Serious Day Tour Man

Getting there

Ferries thread out of the city and into the Marmara, dropping the skyline behind — take the right side outbound for the best of it and a seat on deck in any weather that allows one. Boats call at Kınalıada, Burgazada, Heybeliada, and Büyükada in sequence; the fast private seabuses shave time and charm off the same route. The Istanbulkart covers everything, and the timetable board at the island pier is your first photograph.

The day

Off the boat at Büyükada, coffee on the clocktower square, then choose transport: a bicycle for the coastal loop, the electric minibus toward the hill, or your own feet. The Aya Yorgi climb from Luna Park meydanı is the island’s set piece — steep, shaded in stretches, and finished with a terrace view over the whole archipelago. Descend to a long fish lunch, swim in season, and walk mansion lanes until boat time. The disciplined leave on the pre-crush ferry; the rest learn the alarm’s lesson standing up.

When to go

May, June, September, and October are the island months: warm enough for the terraces, short of the July-August density. Summer midweek works with the early-boat plan. Winter ferries still run to quiet, shuttered islands — a moody half day for the ride and the pines, most things closed, and the fish restaurants that stay open glad to see you.

Frequently Asked Questions

Which island should I choose?
Büyükada for the full version — mansions, the monastery climb, the loop. Heybeliada for the same atmosphere at lower volume. First-timers with one day: Büyükada.

How do I get around without cars?
Walk, rent a bicycle, or ride the electric minibuses that replaced the phaetons. The island center needs nothing but shoes.

Is the Aya Yorgi climb worth it?
Yes — the best view in the islands and the reason to come in shoes that climb. Thirty steep minutes; the terrace at the top serves drinks.

Can I swim?
In season, from clubs and platforms around the shore — most charge day rates for loungers and ladders. The water is the Marmara: swimmable, not Aegean.

Ferry or sea bus?
The slow Şehir Hatları ferry is the experience; the fast boats are for schedules. Take the slow one at least outbound.
