Folegandros has no airport, and its harbour at Karavostasi is built for ferries rather than cruise ships. Those two facts explain both how you get there and why the island stays as quiet as it does.

Two ways, and most people take the second
Direct from Piraeus. It runs, and it is a long southern crossing. Conventional and faster services both appear on the route in season.
Via Santorini. The nearest airport is on Santorini, and the hop across is short. That is how most visitors actually arrive, and it is why the two islands are so often paired.
We print no durations or fares. They are set per season by each operator and they change; the route does not. Confirm the day’s sailings before you rely on a connection.
The practical consequence: if you are flying into Greece and Folegandros is the target, look at flights to Santorini rather than at the Piraeus timetable. Santorini to Folegandros covers that leg.
Where it lands
At Karavostasi, a small village on the south-east coast where every boat lands. The Chora, which is the reason to come, sits up on the cliff above it.
A bus meets the boats and takes you up. Stay in the Chora rather than at the port: the town standing on the lip of a high sea cliff is the entire proposition, and Karavostasi is a harbour.
Why no cruise ships call
Worth stating because it is the mechanism behind the island’s character. The big liners that unload thousands onto Santorini’s caldera each morning do not call at Folegandros, because Karavostasi is a ferry harbour rather than a cruise port.
So the island never fills the way its famous neighbours do, even in August. Rooms in the Chora are limited for the same reason, which is the one thing to book early.
Booking, and the wind
This is an exposed southern corner of the Cyclades and sailings are weather-dependent. A cancelled boat here is a genuine possibility rather than a remote one, and when a ferry is cancelled sets out what happens.
The planning rule that follows: leave a day’s slack between your last island and your flight home. That is worth more than any timetable.
Where this leaves you
No airport, one small harbour, and two ways in: the long run from Piraeus or the short hop from Santorini, which is what most people use. The boat lands at Karavostasi and the Chora is above it, which is where you should stay. Cruise ships cannot call, which is why the island is what it is, and rooms are limited for the same reason. Book them, and leave slack at the end of the trip.
Quick answers
Is there an airport on Folegandros?
No. The nearest is on Santorini, and the hop across from there is short, which is how most visitors arrive. The direct ferry from Piraeus is a long southern crossing.
How do you get from Athens to Folegandros?
Either directly by ferry from Piraeus, which is long, or by flying to Santorini and taking the short crossing from there. The second is what most people do, and it is usually faster overall.
Where does the ferry land on Folegandros?
At Karavostasi, a small village on the south-east coast. The Chora, which is the reason to come, sits above it on the cliff, and a bus meets the boats to take you up.
Why is Folegandros quieter than Santorini?
Because of what it never built. There is no airport, there is one small ferry harbour, and the cruise liners that call at Santorini cannot use Karavostasi. The island simply never fills the same way.
