HI All
We are looking at visiting Greek Islands around late March/early April 2026. Can anyone please tell me when the ferry timetables come out or how I can get an idea of what they may be. In the early stages of planning yet but are looking at doing Greek Islands and Turkey (2 weeks in each). Would like to visit Rhodes or Crete along with Mykonos and Paros maybe. Any ideas or suggestions of what best to do in these areas would be very much appreciated.

I trust someone else will chime in with the ferry info, but FWIW, 2 weeks is VERY little for Turkey and also VERY little for the Greek islands, Crete easily merits a week or two, etc. I'd encourage you to do a LOT more research before committing to this plan. Do you already have good guidebooks? I''d recommend the Moon Guide for Turkey and the Rough Guide for Greece.

You might find some useful information in my trip reports.

Enjoy your planning!

The openseas.gr website allows you to see ferry services in the past as an indicator of future services.

I agree that 4 weeks to accomplish your plan sounds ambitious. You might want to be more selective so you’re not rushing around.

Thank you for your suggestions. Will certainly read up on them.

Ferry schedules for the Greek islands usually start coming out in late winter or early spring, so you’ll likely see more details early next year for your 2026 trip.

Also, you can currently catch ferries from both Rhodes and Mykonos over to the Turkish coast, which is great if you want to split time between Greece and Turkey.

If you’re still figuring out which islands might suit you best, there’s this fun little quiz that matches your travel style to the perfect island—could be a cool way to get some ideas!

Dreamon is right: have a look at openseas.gr.
Timetasbles on the main lines like
Piraeus (port of Athens) - Herakliion
Piraeus (port of Athens) - Chania
Piraeus (port of Athens) - Paros
Piraeus (port of Athens) -Mykonos
Piraeus (port of Athens) - Kos - Rhodos
don't change much from year to year.

I don't think that the Mykonos - Turkey ferry will run in March/April already.
You may check Kos - Bodrum, Rhodos - Marmaris or Rhodos - Fethiye.
You may also combine Mykonos with Samos Island and Kusadasi/Ephesos (Turkey).

The timetable of the Crete - Rhodos ferry is usually published very late and chanages from year to year.
You may also check if there are direct flights between Heraklion and Rhodos on your dates.
