Travel by Ferry
There is a quite regular ferry connection between Sikinos and Piraeus port, as ferry routes are carried out approximately 3 times per week. However, the duration of the trip is about 9 hours.
You can also reach Sikinos from other islands of the Cyclades complex, like Santorini, Folegandros, and Ios. The trip from Santorini to Sikinos lasts 2-3 hours.
