Sifnos has no airport, so you arrive by sea, or by helicopter if the budget allows. Most visitors fly into Athens, board a ferry at the port of Piraeus, ideally a high-speed one, and step off at Kamares on the island's west coast. It is an easy trip once you know where the boats leave from, how long they take and how far ahead to book.
How do you get to Sifnos from Athens?
Most ferries to Sifnos leave from Piraeus, Athens' big, busy ferry terminal. Three companies serve the route: SeaJets, Fast Ferries and Aegean Sea Lines, with a mix of conventional ferries and high-speed catamarans. Boats normally depart from gates E6, E7, E9 and E10, and digital boards in the terminal usually show which gate yours uses, so confirm it on the day. The port is well connected and clearly signposted.
Many boats call at other islands on the way, typically Kythnos and then Serifos before Sifnos. On a direct boat, a sign at the back of the ferry lists the islands and the order in which it will stop at them. When you hear Sifnos, get off quickly, because the stop can be short.
Sailings follow the season. Boats run far more often in summer than in the quieter months, and weekends tend to have more departures than weekdays. Schedules change from time to time, so check the current one before you commit to anything.
There's also a second, quieter departure point: Lavrion, about 40 minutes southeast of central Athens, with a crossing of about 3 hours. It makes sense if you're staying on the southern side of the city and want to avoid the Piraeus crowds. Fewer visitors use it, and fewer boats leave from it, so check its schedule carefully.
How do you get to Piraeus?
From central Athens, the metro is the simplest route. It runs straight to Piraeus, the last stop on the line, and the station sits right next to the port, about 25 minutes from Syntagma or Monastiraki. From the airport, the X96 bus is the budget choice and runs day and night.
A taxi is faster from either place but costs more. Count on roughly 20 to 30 minutes from the city center and 45 to 60 minutes from the airport, longer in heavy traffic. With heavy luggage or an early boat, a taxi or a pre-arranged private transfer is the calmer choice, since app rides can cancel at the last minute.
Leave earlier than you think you need to, and be at the boarding gate at least an hour before departure. For an early-morning sailing, a hotel near the port the night before takes the pressure off.
Is it better to take the ferry or fly to Sifnos?
Take the ferry. No commercial flight lands on Sifnos, and the ferry is the standard way in, with more sailings in summer and none of the airport queues or baggage waits.
The nearest airport is on the small island of Milos, which mostly handles domestic flights from Athens, followed by a short ferry to Sifnos. That combination can cut a leg out of an island-hopping trip, for example flying home to Athens from Milos at the end. For a straight Athens to Sifnos run, though, it usually only adds steps.
The helicopter is the premium option. One company offers transfers from Athens year-round, with about 40 to 50 minutes in the air and views over the Cyclades. It suits weddings, honeymoons or a group splitting the cost. Book well ahead, especially for July and August.
Who should pick what?
- First trip: high-speed ferry from Piraeus.
- Family with luggage: high-speed ferry, with a taxi arranged at each end. Luggage generally travels with you for free, and the quicker crossing is kinder to small travelers.
- Tight budget: conventional ferry, which usually costs less than the fast boats but takes longer.
- Special occasion: helicopter.
- Arriving from Mykonos or Santorini: skip Athens and go island to island.
How long is the ferry to Sifnos?
The quickest boat, run by SeaJets, makes the Piraeus to Sifnos crossing in about two and a half hours. Conventional ferries and boats with extra stops take longer, up to about 5 hours and 40 minutes. That rules out a day trip: there's no return ferry the same day, so plan at least two days on the island.
Aegean winds can slow things down, and Greek ferries are known for running late, so build in slack before any flight home. If you get seasick, the high-speed boat is worth the extra money, since the seas can turn rough when it's windy. Pack motion-sickness tablets either way.
Whatever the boat, bring sunscreen, a hat and a light jacket. Decks are sunny and windy, and indoor lounges can be chilly.
High-speed ferry
Fast catamarans cost more than conventional boats, but they cut the travel time sharply. They're comfortable too, with air conditioning, cushioned seats, TVs and snack bars, a bit like a plane that happens to float.
Conventional ferry
Conventional boats are slower and cheaper. The food onboard is basic, so pack your own picnic of water, bread, cheese and olives, and eat on the deck as the sun drops. Vegans in particular should bring their own, since much of the onboard food contains dairy.
How do you get to Sifnos from other islands?
Sifnos works well as one stop in a Cyclades trip. Ferries link it with Serifos, Milos, Kimolos, Paros, Santorini, Syros and Folegandros. Typical crossing times:
- Serifos: 20 to 40 minutes
- Kimolos: 1 hour
- Santorini: 2.5 to 3 hours
- Syros: about 5 hours and 10 minutes
Times vary with the boat and the number of stops, so treat them as a rough guide. Some island connections may run only once or twice a week, and many connections can change from year to year, so confirm yours before you build a trip around it.
Mykonos and Santorini both have international airports, so you can fly in from Europe and skip Athens altogether. The sea route from Mykonos may include a short stop at Paros.
How do you book ferries to Sifnos?
Book ahead. Fares tend to rise as the date approaches, and boats fill up fast in July and August, on weekends and around holidays. Booking early also tends to bring more flexible changes.
Online booking sites let you compare operators, schedules and prices in one place, and the exact departure times appear when you book. Double-check them, since they differ by day and by boat. If you plan to bring a car, reserve early, because space is limited to certain vessels.
Bicycles are typically accepted and often travel free, with any cost shown at checkout. Pets are allowed on many ferries, though the rules differ by company, so check with yours. Some discounts exist, for instance for certain Greek students and large families, but they're state-regulated benefits that need verification and won't apply to most visitors.
For the return, don't wait. Sunday evening boats back to Athens fill early with people heading back to work, so buy that ticket as soon as you know your plans.
How do you get from the port to your hotel?
Ferries from Athens and the other islands all dock at Kamares, a small village with cafes, tavernas, shops and car rental agencies. The arrival is a bit chaotic, with cars, trucks and people spilling off the boat, but it settles within minutes.
The capital, Apollonia, is about 3.5 miles (5.7 km) away, roughly a 10-minute drive. Artemonas is about 4.9 miles (7.9 km) and Platis Gialos about 8.8 miles (14.1 km). Remote spots like Heronissos, at the northern tip, are 30 to 35 minutes by road.
Your options:
- Hotel transfer: many hotels run a minibus or shuttle to the port. Contact yours before you travel to arrange it.
- Bus: the stop is on the coastal road, a few hundred yards from the port, with service to Apollonia and Artemonas. Buses on the main routes, such as Kamares, Apollonia and Platis Gialos, don't run often, so check the current timetable before you count on one.
- Taxi: there are around 10 on the whole island, so in summer a pre-booked taxi or private transfer is the safer bet. WhatsApp is the easiest way to reach a driver.
- Rental car or ATV: the best way to see the island, with agencies at the port and in Apollonia. Roads are mostly good, with some narrow, winding stretches. Book ahead in high season.
If you plan to drive, bring the right paperwork. Greek law requires U.S. visitors to carry a valid U.S. driver's license, and insurance companies may require an international driver’s permit.
What should Americans know before they go?
U.S. citizens can enter Greece without a visa for up to 90 days of tourism, and the passport should have at least three months of validity beyond your planned departure date. Be ready to show proof of sufficient funds and a return ticket or other evidence of departure if asked.
The U.S. State Department rates Greece as a generally safe destination, though petty crime is common in tourist areas and on public transportation, especially the metro, so keep an eye on your bag on the way to Piraeus. Transportation strikes can interrupt buses, taxis, seaports and airports, and demonstrations may happen with little notice. On the day before your crossing, check your departure time and any strike or weather news, and leave extra slack around any ferry you can't afford to miss.
