i will stay in polichrono or hanioti 3-4 days and then ai want to go in mykonos 2-3 days....can anyone help me with some advice, how to get in mykonos from halkidiki?

From Nea Moudania (at the beginning of the peninsula of Kassandra) there are ferries to Skiathos and Skopelos. These are the nearest islands.
But Mykonos is a looooooooong way... Perhaps you first have to go to Piraeus, the harbor of Athens. From that harbour there are ferries every day.

You can get the ferry to Mykonos from Thessaloniki, look on greekferries.com

Hi, I have the same problem, "j" ... greekferries.com is not working anymore unfortunately...do you have any ideea how I can get a price quote or a ferry timetable from halkidiki to mykonos...I will be grateful, thanks
