Piraeus to Santorini takes roughly 5 hours on the fastest catamaran and around 7 to 9.5 hours on a conventional ferry, depending on the ship and the number of island stops. Blue Star Ferries, Seajets and Fast Ferries all sell the route; foot passengers board at Piraeus gates E6 and E7 and should check in 60 minutes before departure. Fast catamarans run mainly from April to October, in winter the timetable is much thinner.
There are two ways to make this crossing, and they are different products. A conventional Blue Star ship is a floating ferry with a car deck, open decks, a café and a crossing time measured in most of a day. A Seajets catamaran is a fast, sealed cabin that gets you there in about five hours when the Aegean is calm; it is also the first to be cancelled when the meltemi blows.
The fare difference is smaller than the experience difference. What you are really choosing is whether to treat the crossing as a day at sea or as transport, and how much buffer you want before a same-day flight or hotel check-in.
- Piraeus gates are far apart. Santorini departures can leave from E6 or E7, or E1 for Blue Star Chios, and the walk between them is long. Follow the gate on the display, not the company logo.
- Seajets does not publish a Piraeus gate, so plan to arrive with time to find the berth.
- The €41 fare is the slow 9–11 hour ship. The 4h 55m catamaran can cost more than double, so compare the actual sailing.
- Athinios has no town at the quay. You need the bus or a taxi to Fira, 18 km away, and the last bus follows the ferry arrivals rather than your plans.
- Fast ferries run mainly April to October. In winter the timetable falls back to a few conventional Blue Star sailings a week.
Step by step: the day of the crossing
The port is the hard part: Piraeus has twelve gates along a long quay, and your gate depends on the vessel, not the company. This is the sequence for a foot passenger.
- T-24 hRe-check your sailing on the operator's site or app and confirm the gate shown on the ticket; Piraeus gate assignments change with the vessel.
- T-90 minArrive at Piraeus on metro M1 or M3, walk or take the free port shuttle to the gate area (E6/E7 for Blue Star Naxos/Delos, E1 for Blue Star Chios).
- T-60 minBe at the gate with your ticket/QR code and ID; large bags go with you, not into a hold.
- T-20 minBoard, drop bags at your seat or cabin and stay on deck for the Caldera approach into Athinios.
- On arrivalWalk off at Athinios and take the KTEL bus or a taxi up to Fira (18 km, €2.70 ordinary fare), then a second bus to Oia if needed.
Seajets does not publish a Piraeus gate for this route, and gates can change at short notice. Check the departure board at the port and confirm the gate on your ticket. The walk from E1 to E7 is more than a kilometre.
Which operator should you choose?
Three companies sell this route, with different ships and very different crossing times. The fastest is not automatically the best choice: it is also the most weather-sensitive.
| Operator | Crossing | Sailings | Foot passengers | Vehicles |
|---|---|---|---|---|
| Blue Star Ferries Conventional ships with car decks. The reliable option in wind. |
7h 41m | daily, year-round | Yes | Yes |
| Seajets Fast catamarans, the first to be cancelled when the meltemi blows. |
4h 55m | several a day in summer | Yes | Yes |
| Fast Ferries Slower conventional and fast ships. |
about 11h | seasonal | Yes | Yes |
If your priority is arriving at a fixed time, book the conventional Blue Star ship. If your priority is a short crossing, book the catamaran and keep the rest of the day flexible.
What the crossing costs
Foot-passenger fares on this route range widely because the fast and conventional products are priced differently. These are realistic starting points, not teaser prices.
| Ticket | Typical price | Basis |
|---|---|---|
| Foot passenger, one way | from €41 | Lowest standard adult fare, November 2026 |
Check what the fare includes: catamaran tickets often have a smaller luggage allowance and a stricter change policy than conventional ferry tickets, and a return bought as two one-ways can cost more than an open return.
The ports: where you actually board
Two very different ports at either end: a working ferry terminal in Athens and a caldera quay below Fira on Santorini.
Port of Piraeus, Blue Star gates E6/E7, or Gate E1 for Blue Star Chios
Blue Star's own Piraeus gate map lists the Santorini-bound Blue Star Naxos and Blue Star Delos at Gate E6 (passengers only) and Gate E7 (passengers and vehicles). The same map puts Blue Star Chios, which also calls at Santorini on its Anafi–Heraklion–Sitia–Rhodes run, at Gate E1. Gates E1 to E9 are separate quays spread around the main port, so the gate matters more than the company name.
Getting there: Metro lines M1 (green) and M3 (blue) both terminate at Piraeus station beside the port: about 20 minutes from Syntagma and about 60 minutes direct from Athens Airport on M3. The port is worked from gates E1–E12 and the quays are long, allow 15–20 minutes to walk to your gate or use the free port shuttle bus.
Athinios (Thira) port
Athinios is listed by the Municipal Port Fund of Thira as one of the island's port zones and is the main passenger and commercial harbour, on the caldera coast below Fira. It is a working quay rather than a town: you disembark onto the port apron and leave by bus, taxi or pre-booked transfer.
Getting there: KTEL Santorini's official fare table (updated 19/05/2026) prices Fira–Athinios port at €2.70 for the 18 km run. Port buses are timed around ferry arrivals, but the published KTEL timetable lists departures from Fira, so confirm the return/connection for your actual sailing. Fira–Oia is €2.20 and the operator's own timetable shows roughly 30 minutes on that leg, so allow the same order of time for the climb up from Athinios plus the onward leg.
Athinios is not Fira. The port is 18 km below the town, reached by a winding road, and the bus connection is timed around ferry arrivals. After dark, or in winter, confirm the last bus before you rely on it.
Cars, pets and luggage
By car: At least 60 minutes before departure; the Piraeus Port Authority requires vehicle owners to be in the waiting area 1 hour before sailing
Pets: Blue Star issues a free pet ticket when you book, it cannot be bought on board. Bring the health book or passport and the microchip number.
Luggage: Catamarans have a smaller allowance than conventional ferries, and large cases are usually handed over at the gangway.
Season and timetable: Conventional ferries sail all year. Fast catamarans run mainly from April to October, and the winter timetable is slower and much thinner.
Alternatives worth comparing
If your date is full or the fast ferry is cancelled, these are the realistic ways to still make the crossing.
Rafina → Mykonos (Golden Star Ferries, 4h 30m) then Mykonos → Santorini
Rafina is much closer to Athens Airport than Piraeus; Golden Star's Andros Queen does Rafina–Mykonos in 4h 30m, and the Mykonos–Santorini leg is about 2h 41m with Seajets. Two tickets, but useful when Piraeus sailings are full.
Piraeus → Santorini on a conventional Blue Star ship only
About 7h 41m but cheaper than the catamaran and far less likely to be cancelled by the meltemi; the right choice if you are travelling with a car.
Piraeus → Naxos or Paros, then Naxos/Paros → Santorini
Breaks the run with a night on an island; the Naxos–Santorini leg is about 1h 15m and both islands are served by the same Blue Star and Seajets ships.

Frequently asked questions
How long does the ferry from Piraeus to Santorini take?
About 5 hours on the fastest catamaran and 7 to 9.5 hours on a conventional ferry, depending on the ship and the number of island stops.
Which gate do I leave from at Piraeus?
Blue Star puts its Santorini ships at gates E6 for foot passengers and E7 for passengers with vehicles, but assignments vary by vessel. Seajets does not publish a gate, so check the port displays.
Can I take a car to Santorini?
Yes, on conventional Blue Star ships and on some catamarans, but not on every sailing. Vehicles must be in the waiting area an hour before departure.
Do the ferries run in winter?
Yes, but on a thinner, slower timetable. Fast catamarans run mainly from April to October, and winter sailings are mostly conventional ships taking 7 to 11 hours.
