The ferry from Santorini to Koufonissi is a fast and popular way to reach the Small Cyclades, giving you a direct connection from busy Santorini to the relaxed island of Koufonissi in under 2 hours. Ferries usually depart from Athinios Port in Santorini and arrive at Koufonissi Port, with around 1 sailing per day and about 7 crossings per week in the main season. The route is mainly operated by Seajets, using modern high speed vessels that are designed for island hopping and are comfortable for foot passengers, with some departures also allowing cars. The average journey time is about 1 hour 50 minutes, and most schedules place the ferry around midday or early afternoon, so you can travel between the islands without rushing in the early morning or arriving too late at night. Ticket prices for foot passengers are on the higher side for a short crossing, with many travellers paying from about €90 up to over €150 in peak periods, but you gain a quick and direct link into one of the most beautiful island groups in Greece. In summer there are usually more weekly sailings than in winter, but this is still a route that sells out, so it is wise to plan and book your tickets in advance, especially for July and August.
Key Information
Ferry duration
The typical ferry duration from Santorini (Athinios Port) to Koufonissi is about 1 hour 50 minutes, with most schedules listing journey times between 1 hour 45 minutes and 1 hour 55 minutes. Because this route is almost always handled by high speed ferries, there is little variation in actual sailing time, so you can safely plan for around 2 hours at sea.
Ferry companies
The Santorini to Koufonissi ferry route is mainly operated by Seajets, which runs high speed catamarans between the two islands. Some booking platforms also list Blue Star Ferries as an option on certain dates or seasons, but the regular daily summer connection is usually a Seajets service.
Fast vs slow ferry
On this particular route there is effectively only a fast ferry option, as the crossing is operated by high speed vessels with journey times around 1 hour 50 minutes. Unlike other Cycladic routes, there is not a clear slow conventional ferry alternative on most days, so travellers who want this direct Santorini to Koufonissi route generally choose between different Seajets departures and fare categories rather than between fast and slow boats.
Best time to travel
The best time to travel from Santorini to Koufonissi is from June to September, when there are regular daily sailings and the sea and weather conditions are usually at their most settled. Outside the peak months, especially from October to May, there are fewer weekly crossings and some travellers instead route via Naxos, so if you plan to travel in shoulder season it is important to check timetables early.
Sea conditions/wind
The sea between Santorini and Koufonissi can be affected by the strong summer meltemi winds, which sometimes make the high speed ride feel bumpy even though the journey is short. People sharing experiences online often mention that Seajets crossings are safe but can be a bit rough on windy days, so if you are sensitive to motion sickness it is a good idea to choose a seat near the middle of the vessel, look at the horizon and keep any necessary medication with you.
Port guide
In Santorini, ferries to Koufonissi depart from Athinios Port, the main ferry harbour at the bottom of the caldera cliffs, which can become very busy when several ferries arrive or leave around the same time. In Koufonissi, the ferry arrives at the small main port in front of the village, where you will find accommodation pick up vans, a limited number of taxis, a few cafes and tavernas and easy walking access to the village and nearby beaches.
Car rental advice
Seajets ferries on the Santorini to Koufonissi route can carry cars on some sailings, and prices for vehicles are significantly higher than foot passenger fares, with ranges shown between about €55 and €150 depending on season and car size. Because Koufonissi is a very small island where many visitors walk or cycle, many travellers recommend returning your hire car in Santorini and then exploring Koufonissi without a vehicle, or hiring a bike on arrival instead of transporting a car on this ferry.
Foot passenger tips
As a foot passenger, you should aim to be at Athinios Port at least 1 hour before your Santorini to Koufonissi ferry departure, especially in July and August when traffic and queues can cause delays. On arrival in Koufonissi, the port area is compact and many hotels meet guests directly at the boat, but if you have not arranged a transfer it is still easy to walk from the ferry to most accommodation in the main village.
“Is this route worth it?”
The Santorini to Koufonissi ferry route is very much worth it if you want to escape the crowds of Santorini and experience the relaxed beaches and turquoise waters of the Small Cyclades without complicated changes. Regular visitors say that although the ticket price can be high, the combination of a direct connection and a short 1 hour 50 minute journey makes this route one of the most efficient ways to include Koufonissi in a Cyclades island hopping itinerary.
Alternative route if canceled
If your direct Santorini to Koufonissi ferry is cancelled, the most common alternative is to travel from Santorini to Naxos and then from Naxos to Koufonissi on a separate ferry, as Naxos is a major hub with very frequent connections to the Small Cyclades. In some cases you might also find options via other islands such as Ios or Paros, so it is sensible to check with Seajets, Ferryhopper or a local travel agency for same day alternatives if the direct route is disrupted.
Reverse route internal links
The reverse ferry route from Koufonissi to Santorini operates with similar journey times of about 1 hour 50 minutes and is also mainly run by Seajets. There are usually around 7 weekly sailings in summer, so it is easy to plan a circular itinerary that starts in Santorini, visits other islands and then returns via Koufonissi or uses Koufonissi to connect back to Santorini for your flight home.
FAQs about the Santorini to Koufonissi ferry route
Can I do a day trip from Santorini to Koufonissi by ferry?
A same day return trip from Santorini to Koufonissi by ferry is not realistic, because there is usually only 1 direct sailing per day in each direction and there is no return ferry that would bring you back to Santorini in the evening. For this reason, travellers and booking sites clearly say that the Santorini to Koufonissi ferry route is best used as part of a multi day stay on Koufonissi rather than for a simple day excursion.
How often does the Santorini to Koufonissi ferry run in summer?
In the main summer months, the Santorini to Koufonissi ferry usually runs once per day, with an average of around 7 weekly sailings. Some seasons see a few extra crossings or small timetable changes, but most travellers planning July and August trips can expect a single daily Seajets departure around midday or early afternoon.
Why is the Santorini to Koufonissi ferry so expensive compared to other routes?
Many travellers notice that Santorini to Koufonissi ferry tickets are expensive for a journey of under 2 hours, and this is largely because the route is served by a high speed operator with limited daily capacity and strong demand in peak season. Prices for foot passengers often range from about €90 to more than €150 in summer, especially when booking close to the travel date or choosing flexible or premium fare categories.
Is the Santorini to Koufonissi ferry suitable for someone who gets seasick?
The Santorini to Koufonissi ferry is relatively short at around 1 hour 50 minutes, but because it is a high speed vessel in open Aegean waters, it can feel lively on windy days. People who get seasick often say that sitting near the middle of the boat, avoiding heavy food and alcohol before departure and using seasickness tablets or wristbands makes the crossing more comfortable.
How far in advance should I book the Santorini to Koufonissi ferry?
For travel in July and August, many experienced island hoppers recommend booking the Santorini to Koufonissi ferry at least 3 to 4 weeks in advance, especially if your dates are fixed. Outside peak summer you may be able to wait a little longer, but because there is usually only 1 sailing per day on this route, it is still wise to secure your ticket several days before departure.
