Darıca - Büyükada Ferry Services 2026
The Darıca - Büyükada ferry line is part of Kocaeli Metropolitan Municipality's special Princes' Islands service organized during the summer months. A single ferry picks up passengers sequentially from İzmit 08:30 → Değirmendere 09:15 → Karamürsel 10:00 → Darıca 11:15 and reaches Büyükada; this allows passengers boarding from different districts of Kocaeli to be transported directly to Büyükada without transfers. Departure from Darıca pier is at 11:15, with arrival at Büyükada around 12:15.
Service Days and Season
Services operate as round-trips every Sunday between June 22 - September 21, 2026. Since the line operates only during the summer season and once a week (Sunday), it is planned for those who wish to enjoy a day trip to the island. The ferry remains in Büyükada all day and begins its return journey at 17:30.
Departure Time from Darıca
- Outbound (Sunday): Darıca 11:15 departure → Büyükada ~12:15 arrival
- Return (Sunday): Büyükada 17:30 departure → Darıca ~18:30 arrival
Since the ferry also calls at other piers along the İzmit Gulf coast before departure, timings are set according to the single ferry's intra-gulf route. Return services from Büyükada to Darıca are listed on a separate page.
Ticket Prices (2026)
Round-trip tour ticket departing from Darıca: 260 TL for adults, 200 TL for students. The price includes both outbound and return journeys; it is structured as a single round-trip tour. Ticket fares vary by departure pier — the Darıca departure, being closest to the island, has the most favorable fare.
Reservation Mandatory
As space is limited on these services, advance reservation is mandatory. Reservations can be made via Kocaeli Metropolitan Municipality's website at kdu.kocaeli.bel.tr or www.kocaeli.bel.tr. It is recommended to book your spot in advance rather than arriving at the pier without a reservation on Sunday morning.
Why the Büyükada Ferry from Kocaeli?
During summer, ferries to the Princes' Islands from within Istanbul become extremely crowded, especially on weekends, with long queues forming at Bostancı and Kabataş piers. This direct service from Kocaeli allows you to reach Büyükada with a pleasant sea journey, completely bypassing Istanbul traffic and crowded transfer piers. The views of both sides of the İzmit Gulf and the Marmara Sea transform the journey itself into a scenic tour.
A Day on Büyükada
Since the ferry arrives at Büyükada before noon, approximately five hours remain for exploring the island. Electric vehicles, which have replaced horse-drawn carriages, bicycle tours, a climb to Aya Yorgi Church, historic mansions, and seaside fish restaurants provide ample time for a day trip. It is recommended to plan your time on the island to be ready at the pier for the 17:30 return journey.
