For a family visiting Santorini, the KTEL public bus network is the cheapest way to move around the island—by a wide margin. A single adult fare runs €2.20 to €2.80, children pay half or ride free, and there are no parking fees, fuel costs, or rental-car deposits. The catch is that the system radiates from one hub in Fira, so most trips between villages require a change there, and the timetable follows its own rhythm. If you understand how it works, you can keep your transport budget to a few euros per day and redirect that money toward accommodation, meals, or experiences.
Every KTEL bus on Santorini starts and ends at the central station in Fira. The network reaches Oia, Kamari, Perissa, Akrotiri, the airport, and the Athinios ferry port, but there are almost no direct routes between two places that aren’t Fira. Getting from Oia to Perissa, for example, means riding the Oia–Fira bus, then the Fira–Perissa bus, with a separate ticket for each leg. The same applies to Kamari to Akrotiri, or Perivolos to Oia. The Fira station itself is a yard with numbered bays, a timetable board, and limited shade—bring a hat and water if you’re waiting in summer.
This matters for families because a day that involves several destinations can require four to six separate tickets per person. The research notes that a round trip from Oia to Akrotiri needs four rides: Oia→Fira, Fira→Akrotiri, Akrotiri→Fira, Fira→Oia. At roughly €2.20 each, that’s €8.80 per adult for that one outing. Still, that’s less than a single taxi ride between the same points, which the sources list at €30–55 depending on the specific route.
As of the latest 2026 fare update, most common routes cost €2.20 per adult. The full price list from KTEL shows Fira–Oia at €2.20, Fira–Kamari at €2.20, Fira–Airport at €2.20, and Fira–Perissa at €2.70. Longer routes like Fira–Vlychada run €2.80. Children receive a 50% discount on many routes (€1.10 for the shorter journeys), and students get about 25% off. Small children often ride free, though the sources don’t state a specific age cut-off. There are no day passes, weekly tickets, or multi-ride cards—every ride is a single one-way fare.
Cash only. The conductor collects the fare after you board. Small coins and €5 notes are best; a €50 note will not be welcome. Some newer buses are trialling tap-to-pay in 2026, but treat cash as your primary option and always carry enough for the return trip too.
Tickets are sold on the bus by the conductor, not at a machine. At the Fira station you may find a kiosk that mostly provides information rather than tickets. For the airport and port routes, payment is usually collected before boarding; on all other routes you board first and the conductor comes to you. The system makes fare evasion nearly impossible, but it also means you need to have the right change ready, especially when the bus is crowded and the conductor is moving quickly.
The network operates on two seasonal schedules. The full summer timetable runs roughly from late April through October, with extra buses added June through September. During these months, the Fira–Oia route runs roughly every 30 minutes from early morning until late evening, and the beach routes to Kamari and Perissa run at similar frequency. The Fira–Akrotiri service runs several times a day rather than every half hour. The airport and port buses are timed around flight and ferry arrivals, so their schedule shifts daily.
Winter—November to March—is a different story. Only a handful of buses run, some routes stop entirely, and evening services are largely absent. The research states that buses on some routes run only until noon, and the return trip may require waiting until the next morning. A family visiting in winter cannot rely on the bus network for anything beyond the most basic connections between Fira and the airport or Oia, and even those run on a much reduced timetable. The safest approach for winter travel is to call the KTEL office at +30 22860 25404 or check the printed board at the Fira station on arrival.
The biggest saving comes from choosing accommodation in or within walking distance of Fira. If you stay in Fira, Firostefani (a ten-minute walk from the station), or Karterados or Messaria (five to ten minutes by bus from Fira), you need only one bus to reach any other point on the island. Staying in Oia or an inland village like Pyrgos means every trip starts with a bus to Fira, adding time and a second fare to any outing.
A typical beach day from Fira costs €4.40 round-trip per adult (€2.20 each way to Kamari or Perissa). A family of four with two adults and two children paying the reduced fare would spend roughly €13.20 for the day. Compare that to a taxi, which the sources list at €18–25 for Fira–Kamari one way, or a rental car that starts at €40–130 per day before fuel and parking. Over a week, the bus saves several hundred euros.
For the airport or port arrival with luggage, the research strongly recommends a pre-booked private transfer (€40–60 for a sedan) rather than the bus. The airport bus costs €2.20 per adult and runs about every hour, but when several flights land together the bus fills immediately. With children, strollers, and suitcases, the stress of queueing for a packed bus with no guarantee of a seat is not worth the €20 saved. Use the bus for daytime sightseeing and book a transfer for the first and last day.
For the sunset trip to Oia, the bus is the cheapest option—€4.40 round-trip per adult—but the return after sunset is the most crowded bus on the island. The research notes that queues of 30 to 40 minutes are normal in summer, and several buses may pass before you board. One workable strategy is to take an early bus to Oia (around 16:30 or 17:00), walk part of the caldera path on the way back to catch a bus at a less crowded stop, or stay for dinner and wait for the crowd to thin before the last bus around 21:40. Alternatively, pre-book a private transfer for the return, which costs €40–55 but guarantees a seat and a timely departure.
The bus network does not serve several key places. The wineries are mostly on roads with no service at all, and the Akrotiri lighthouse is a 20-minute walk past the village bus stop. Ancient Thira has no bus—you walk up from Kamari on a steep path in full sun. The Red Beach is reachable on foot from the Akrotiri stop, but the access is periodically closed by rockfall. None of these are day trips you can do by bus alone.
The coaches are not wheelchair accessible. They have steps and no lift, and most stops lack dropped kerbs. For a family member with mobility difficulties, a private vehicle is the only realistic option. Similarly, if you are travelling with a pushchair and a toddler, the combination of crowded buses, standing room only on popular routes, and the walking required between the bus stop and your accommodation can make the bus more hassle than it saves.
Strikes by Greek public transport unions occasionally affect services. They are rare and usually announced in advance, but during a strike buses may not run at all, or drivers may keep only key routes at their discretion. There is no backup system, so families should have a contingency plan—a pre-booked transfer or a hotel that can arrange a car—if they are visiting during a period of known strike activity.
Photograph the timetable board at the Fira station before you set off each day. The board is the single most reliable source on the island, and timetables change without notice. Always check the last return time for wherever you are going—the research identifies this as the most common mistake families make.
Carry small coins and €5 notes. The conductor moves fast, and large notes slow down the queue. On the Fira–Oia run in the late afternoon, board early if you want a seat for the children. Sit on the right side leaving Fira for the caldera view. Ask the conductor to tell you when your stop is approaching—they speak English and are used to the question.
Allow at least an hour for any journey that involves a change in Fira. If you are going from Kamari to Perissa, for example, the bus to Fira takes about 20 minutes, you wait for the connection, and then the bus to Perissa takes another 25 minutes. A 15-minute drive becomes an hour. Plan your day around that rhythm and you will avoid the frustration of missed connections.
For families who want to visit the wineries, Ancient Thira, or the Akrotiri lighthouse, the research suggests booking a private driver for one or two days. A half-day driver for up to four people costs roughly €120–180, which split across a family is cheaper than a week of car hire and parking, and it reaches everything the bus cannot. The bus handles the beaches, Oia, and the airport; the driver handles the sightseeing that requires a vehicle. That combination keeps your total transport spend well under what most families pay for a rental car.

Reader questions about Santorini buses
Can I use a credit card to pay for the bus?
No. Buses accept cash only. Some newer vehicles are testing tap-to-pay in 2026, but you should always carry euro coins and small notes.
Is there a direct bus from the airport to Oia?
No. You take the airport bus to Fira (€2.20, about 10 minutes) and then change to the Fira–Oia bus (€2.20, about 25 minutes). With luggage, a pre-booked transfer is a better choice for most families.
How much does a taxi cost from Fira to Oia?
The research lists Fira–Oia taxi fares at €25–35, and airport–Oia at €40–55. With only about 30 licensed taxis on the entire island, finding one at peak times is unreliable.
Do buses run to the cruise port?
No road serves the old port where cruise ships dock. Passengers reach Fira by cable car, by walking 588 steps, or by donkey. The bus network starts at the top of the cable car in Fira.
What time is the last bus from Oia to Fira in summer?
The summer timetable shows the last Oia–Fira departure at 21:40, arriving in Fira around 22:05. After that, your only option is a taxi or a pre-booked transfer.
