İDO runs its Greek-island crossings as a summer service: in 2026 Dikili–Lesvos started on 22 April and most lines were planned until the end of September, with some October dates on sale. Its boats take foot passengers and bicycles only. Book at egeadalari.ido.com.tr or through the call centre 444 44 36; for winter crossings the year-round operators are Ertürk Lines, Turyol and Jalem Tur.
İDO (İstanbul Deniz Otobüsleri) sells its Aegean island crossings on a separate site, egeadalari.ido.com.tr. In March 2026 it announced a season of ten routes to six Greek islands – Chios, Lesvos, Samos, Patmos, Leros and Rhodes – from ports including Dikili, Seferihisar, Kuşadası, Turgutreis and Fethiye (the announcement itself names nine routes). Its Aegean travel rules cover foot passengers and bicycles only; we found no vehicle carriage.

How to book
Book online at egeadalari.ido.com.tr or through İDO’s call centre (444 44 36). Check-in at İDO’s port sales office closes 1.5 hours before departure (Sığacık Teos Marina for Seferihisar, Ege Port for Kuşadası). Tickets must be in the name shown in your passport and cannot be transferred; you can change a ticket once (new date or open ticket) if you tell the sales office at least 24 hours before departure, and open tickets expire at the end of the season. The timetable menu on İDO’s site also lists Bodrum–Kos and Kaş–Meis, but we saw no sailings for them.
Vehicles
No vehicles as far as we could verify. İDO’s Aegean travel rules mention only bicycles – each ship takes up to 10 on the Samos and Dikili–Lesvos lines, and you must declare a bike when booking. If you want to take a car, see taking a car to the Greek islands.
Luggage and pets
Each passenger may bring one suitcase or one piece of hand luggage; İDO may charge for or refuse extra baggage. Wheelchairs travel free on top of the allowance. Pets are not accepted on the Aegean island sailings; guide dogs of visually impaired passengers are the exception (harness and muzzle required).

FAQ
Can I take my car on an İDO ferry to the Greek islands?
No vehicle carriage is mentioned in İDO’s Aegean rules; only bicycles (up to 10 per ship on some lines). For a car, look at Ayvalık–Lesvos or Çeşme–Chios, where car ferries run.
Can I bring my dog?
No. İDO does not accept pets on its Aegean island sailings. Only guide dogs of visually impaired passengers are allowed.
Which İDO routes are confirmed for 2026?
Dates are published for Dikili–Lesvos (from 22 April), Seferihisar–Samos (from 1 May), Kuşadası–Samos (from 22 April), Kuşadası–Patmos (from 26 May) and Turgutreis–Leros (mid-May to end of September). Fethiye–Rhodes was planned too. For Ayvalık, Akçay and Çeşme we could not confirm that İDO sailings ran.
How early do I need to be at the port?
İDO asks you to check in at its port sales office at least 1.5 hours before departure. Tickets are checked at the ship’s door after passport control.
Does İDO sail to the Greek islands in winter?
We found no İDO winter timetable. Its 2026 Aegean lines were announced as a summer service (Dikili–Lesvos from 22 April, most lines planned until the end of September, some October dates on sale), and the timetable menu on its site showed no Bodrum–Kos or Kaş–Kastellorizo sailings. In winter use Ertürk Lines or Turyol to Chios and Lesvos, or Jalem Tur to Lesvos.
