Travel by Ferry
There are ferry routes from the port of Piraeus, in Athens to Kimolos, so you can reach this lovely island from Athens! However, the trip lasts 7-8 hours and there are only few routes.
There is a small local ferry that connects Milos to Kimolos. A popular way to reach the island is to first go to Milos as there are more available routes and then take the small local ferry to Kimolos.
Kimolos is also connected with some other islands of the Cyclades, like Milos, Kythnos, Serifos, Sifnos and many more.
