The ferry from Santorini to Sikinos is a small but very useful connection within the Cyclades, linking the busy island of Santorini with the quiet, traditional island of Sikinos in around 2 hours on average. Departures are from the main Athinios Port in Santorini and arrive at the small port of Alopronia in Sikinos, with several sailings per week depending on the month and ferry company. Services are usually operated all year, but with more frequent crossings from June to September and fewer sailings during the winter months. The route is mostly served by conventional ferries, which can carry both foot passengers and vehicles, and ticket prices for adults typically start from about €6 for a simple economy seat, making it one of the most affordable inter island hops in the region. In the high season you can often find 4 to 6 crossings per week, while in the low season there may be only 1 or 2, so it is important to check the latest timetable when planning your trip. Although the crossing is relatively short, sea conditions in the Cyclades can be windy, especially when the meltemi blows in summer, so you should allow some flexibility in your schedule for occasional delays or changes. Overall, this route is ideal for travellers who want to escape the crowds of Santorini and experience a more authentic Cycladic island without spending too much time or money on travel.
Key Information
Ferry duration
The typical ferry duration from Santorini (Athinios Port) to Sikinos (Alopronia Port) is around 2 hours, with most direct sailings falling between 1 hour 50 minutes and 2 hours. Some services that stop at another island on the way, such as Ios, can take a little longer, but for most travellers you can expect to be on the boat for about 2 hours of actual sailing time.
Ferry companies
Several companies are involved in the Santorini to Sikinos connection, including Fast Ferries, Maistros Santorini (Boatmen Union of Santorini) and other operators that serve Sikinos as part of their Cyclades network. Many schedule and booking sites list Cyclades Fast Ferries as the main operator on this specific route, with roughly 3 weekly sailings in the core season.
Fast vs slow ferry
On this route there is not a huge difference between so called fast and slow ferries, because even the conventional vessels complete the journey in about 2 hours. However, some modern ferries may offer slightly quicker crossings, more comfortable seating and better stabilisation, while the slower traditional ferries feel more relaxed and allow you to enjoy the sea views from the open deck.
Best time to travel
The most reliable and convenient time to travel this route is between June and September when there are more weekly departures and the weather is usually settled. Outside the high season, especially in early spring and late autumn, the number of sailings can drop to around 1 per week, so if you are travelling then you should plan your dates around the ferry timetable rather than leaving it to the last minute.
Sea conditions/wind
The Cyclades are known for the strong summer meltemi winds, which can create choppy seas and occasional disruption even on short routes like Santorini to Sikinos. On windy days you may feel more movement on the boat, so if you are prone to seasickness consider sitting on an outside deck, keeping your eyes on the horizon and having medication or ginger sweets ready just in case.
Port guide
In Santorini the ferry leaves from Athinios Port, the main ferry harbour located below the cliffs and connected to the rest of the island by a winding road used by buses, taxis and transfer minibuses. In Sikinos the ferry arrives at Alopronia Port, a small, calm harbour that also functions as the island’s main village by the sea, with a few rooms to let, tavernas, a mini market and bus and taxi connections up to the hilltop Chora.
Car rental advice
You can take a car on the Santorini to Sikinos ferry on certain departures, with average vehicle prices shown around €20 to €32 each way depending on season and availability. Many travellers, however, choose to drop a hire car in Santorini and explore Sikinos on foot or by local bus and taxi, because the island is quite small and has limited road networks compared to Santorini.
Foot passenger tips
Foot passengers should arrive at Athinios Port at least 1 hour before departure in high season, because traffic, bus arrivals and check in queues can all cause delays. On arrival in Sikinos, it is sensible to pre book accommodation transfers or check the local bus timetable in advance, as services are limited and taxis can be few when several passengers disembark at once.
“Is this route worth it?”
This ferry route is very much worth it if you want to balance a stay in iconic Santorini with time on a quiet and authentic island like Sikinos without spending long hours on a boat. Many experienced travellers in Greek island forums say that Sikinos offers a peaceful contrast to Santorini’s crowds and that the short 2 hour crossing is a small effort for a big change of atmosphere.
Alternative route if canceled
If your direct Santorini to Sikinos ferry is cancelled, the most realistic alternative is usually to travel from Santorini to Ios and then from Ios to Sikinos on a separate ferry, since Ios has frequent connections with both islands. In a more serious disruption you might need to route through another hub island such as Naxos or Folegandros, so it is wise to keep your schedule flexible and check with ferry companies or local agents for same day options.
Reverse route internal links
If you are planning your trip in the opposite direction, you can take the Sikinos to Santorini ferry, which offers similar journey times ranging from about 1 hour 25 minutes to 2 hours and uses the same ferry companies. Ticket prices for Sikinos to Santorini are usually the same as the outbound route, so you can plan a simple return journey between the two islands with a mix of dates and operators to suit your itinerary.
FAQs about the Santorini to Sikinos ferry route
Can I do a day trip from Santorini to Sikinos by ferry?
In practice it is very difficult to do a true day trip from Santorini to Sikinos by ferry, because most Santorini to Sikinos departures are later in the day and the return Sikinos to Santorini sailings do not line up for an evening ride back. Travellers in Greek island travel groups often note that schedules make a same day visit almost impossible, so it is better to plan at least 1 or 2 nights on Sikinos if you take this ferry route.
How often does the Santorini to Sikinos ferry run in summer?
In the main summer months there are usually around 4 to 6 Santorini to Sikinos crossings per week, depending on the combination of Fast Ferries, Maistros Santorini and other operators serving the line. Schedules can change from year to year and even within the season, so travellers frequently mention on forums that they wait until spring for confirmed timetables before finalising island hopping plans on this route.
Is the Santorini to Sikinos ferry ever cancelled due to weather?
Yes, the Santorini to Sikinos ferry can be cancelled when strong meltemi winds or rough seas affect the Cyclades, especially in July and August. People sharing experiences online say that short routes like Santorini to Sikinos are often among the first to be reinstated once conditions improve, but you should avoid tight connections on the same day as your flight or another important booking.
Do I need to book the Santorini to Sikinos ferry far in advance?
For high summer dates, many regular visitors recommend booking the Santorini to Sikinos ferry a few weeks in advance, particularly if you are travelling with a car or need specific dates. Outside peak periods there is usually more availability, but travellers on forums still advise buying tickets at least several days before departure because services on this route are limited and can sell out on busy days.
Is the Santorini to Sikinos ferry comfortable for someone who gets seasick?
The Santorini to Sikinos ferry is a relatively short crossing of around 2 hours and many boats on this route are conventional vessels with indoor lounges and open decks, which helps passengers find a comfortable spot. However, because the sea between Santorini and Sikinos can be choppy when the wind is strong, travellers who get seasick often suggest booking a morning sailing when conditions are usually calmer, sitting near the centre of the boat and bringing travel sickness medication just in case.
