Ferry from Santorini to Kea

At the moment there is no regular, direct ferry operating from Santorini (Thira) to Kea (Tzia), even though some older timetables and generic tools mention the route in theory. Current schedule providers state clearly that there are no direct Santorini–Kea sailings now, and journey planners instead suggest travelling via another island such as Syros, Kythnos or via the Athens port of Lavrio, which has frequent ferries to Kea all year. In practice this means you can still combine Santorini and Kea in one trip, but you need to plan at least one connection, for example Santorini–Syros–Kea or Santorini–Lavrio–Kea, and allow a full day of travel. Because any direct Santorini–Kea sailings are not shown in the main 2026 timetables, it is safest to treat this as a multi‑leg itinerary rather than relying on a single ferry.

Key Information

Ferry duration

Older and marketing‑style pages sometimes quote a single direct Santorini–Kea sailing time of about 7 hours to 7 hours 5 minutes when Seajets has operated this as part of a longer Cyclades route. With no current direct ferry listed, the realistic duration is for an indirect journey, for example around 6 hours 40 minutes by ferry via Syros (about 3 hours 5 minutes Santorini–Syros plus about 2 hours 35 minutes Syros–Kea, plus transfer time).

Ferry companies

Kea is served by several companies overall, including Blue Star Ferries, Goutos Lines, Karystia Lines, Magic Sea Ferries and Triton Ferries, mainly on routes from Lavrio and some nearby islands. Seajets is mentioned as an operator that has at times connected Santorini with Kea on extended Cyclades lines, but current 2026 route and operator pages say there are no direct Santorini–Kea sailings now.

Fast vs slow ferry

When Seajets has run a Santorini–Kea connection in the past, it used high‑speed vessels, with the full journey quoted at around 7 hours, and it did not carry vehicles. For a modern itinerary via another island or via Lavrio, you will usually mix different ferry types, such as a faster high‑speed ferry from Santorini to Syros and then a slower conventional ferry from Syros or Lavrio to Kea, so overall speed depends on the specific legs you choose.

Best time to travel

The easiest time to travel between Santorini and Kea via other islands is from May to October, when there are frequent ferries across the Cyclades and daily or near‑daily sailings between Lavrio and Kea. In winter the Kea–Lavrio line still runs multiple times per week, but some of the Cyclades island‑to‑island routes from Santorini operate less often, so you may have to plan an overnight stop in an intermediate island or in Athens.

Sea conditions/wind

The sea areas between Santorini, the central Cyclades and Kea are exposed to the meltemi wind in summer, which can produce choppy conditions and occasional delays. Larger conventional ferries on the Lavrio–Kea or Syros–Kea legs are usually more stable than small high‑speed catamarans, so travellers who get seasick often choose those ships when possible, sit centrally and carry motion sickness remedies.

Port guide

In Santorini, any ferry you use for the first leg of this trip will depart from Athinios Port, the main harbour below the cliffs, served by buses, taxis and hotel transfers from Fira, Oia and other villages. In Kea, ferries arrive at the port of Korissia (Kea’s main harbour), which has tavernas, basic services and bus and taxi links to Ioulida (Chora) and other parts of the island, and is the starting point for routes back to Lavrio and other Cycladic islands.

Car rental advice

Because there is no straightforward direct Santorini–Kea ferry and some historic routes mention “foot passengers only”, taking a car all the way from Santorini to Kea can be complex and expensive. A more practical approach is usually to return a hire car in Santorini, travel as a foot passenger via a hub such as Syros or Lavrio, and then rent a car again on Kea, where local agencies serve the island’s small road network.

Foot passenger tips

As a foot passenger, it helps to treat this as an island‑hopping route: for example, book a ferry from Santorini to Syros or another central Cyclades hub, stay flexible, and then continue by ferry to Kea on the next available day. If you choose the Lavrio option, you can sail from Santorini to Piraeus or Rafina, then travel overland to Lavrio and catch one of the many short ferries (around 1 hour) from Lavrio to Kea.

“Is this route worth it?”

Even though there is no simple direct ferry, combining Santorini and Kea can be worthwhile if you like the idea of pairing a very famous island with a quieter weekend‑style escape close to Athens. Many route guides highlight Kea’s hiking paths, coves and small villages, so if you are happy to spend a travel day via Syros or Lavrio, you can experience two very different sides of the Cyclades in one trip.

Alternative route if canceled

Because there is no scheduled direct Santorini–Kea ferry running now, your “alternative” from the beginning is to travel via another island or via Athens. The most practical indirect options are Santorini–> Syros–> Kea, or Santorini–Piraeus/Rafina then overland to Lavrio and Lavrio–Kea, with the choice depending on your wider itinerary and how much time you want to spend in Athens versus other islands.

Reverse route internal links

In the reverse direction, some route planners describe a Kea–Kythnos–Santorini combination, with 3 weekly ferries between Kea and Kythnos that connect into lines towards Santorini. However, current 2026 tools still show no direct Kea–Santorini sailings, so both directions should be treated as multi‑leg journeys using the same via‑island or via‑Lavrio approach.
