Kythnos island is one of the easiest to reach from Athens, by taking a ferry from either Piraeus or Lavrio ports, with services running daily.
The trip from Piraeus, covering about 52 nautical miles, takes around three hours on modern vessels. If you're departing from Lavrio port, it's a shorter trip of roughly 25 nautical miles, taking less than two hours.
There are connections available from Kythnos to most of the other islands in the Cyclades throughout the year. Kythnos lacks an airport, with the only option for air travel being helicopter. The island's heliport is conveniently located near the town center and is mainly used by private helicopter charter services transporting wealthy visitors or for emergency medical airlifts to the Syros hospital or to facilities in Athens. For those who prefer to use their own boats, the island offers numerous anchorage points and two marinas.
How to access Piraeus Port
There are three choices for transportation from Athens Airport to the Piraeus port: the public bus, the metro, or traditional taxis.

A more budget-friendly alternative is the bus, which costs just 6€, though it may take over an hour to make the journey (line X96). Another option is the metro, which charges 10€ for a single trip and typically takes around 85 minutes to arrive at the Piraeus port.
