Travel from Istanbul to the Greek islands is made either by flight via Athens to the destination island, or by ferry from ports on Türkiye's Aegean coast. Ports on the coast serve Lesbos, Chios, Samos and Kos; the Athens connection is the main option for Santorini, Mykonos, Crete and Corfu. Sailing, visa and passport conditions should be checked with official sources before the travel date.
The most practical way to get from Istanbul to the Greek islands is either to fly via Athens to the destination island, or to travel to a port on Türkiye's Aegean coast and take a ferry. Since there is no regular, direct ferry link from Istanbul to all the islands, flight time, access to the coastal port and border procedures should be weighed together when choosing a route. For islands such as Lesbos, Chios, Samos and Kos, a ferry from the coast is the natural choice; for Santorini, Mykonos, Crete and Corfu, most travellers find a flight via Athens the main option.
The main route for reaching the Greek islands by plane from Istanbul is a connection through Athens. Flying from Istanbul to Athens, then looking for a domestic connection from the same airport to the destination island, is the most predictable air option on days when there is no direct flight to the island. Because flights and connections change by date, before buying a ticket, check on the official airline screen that the two flights operate on the same day with a suitable connection window.
The Athens connection is especially useful for islands that are not close to Türkiye, such as Santorini, Mykonos, Crete and Corfu. When you arrive in Athens from Istanbul and then fly to the island, do not look only at the time on paper. Leave a reasonable connection window for baggage delivery, re-screening, passport procedures and possible delays.
As an alternative, you can fly from Istanbul to Athens, spend a few days in the city and then cross from Piraeus port by ferry. This model works better for island-hopping by sea, such as the Cyclades or regions linked by sea to Crete, than for flying to a single island. Getting to Piraeus and the port terminal should be planned separately from the airport where your flight lands.
To make an island holiday by ferry from Istanbul, you first need to reach one of the departure ports on Türkiye's Aegean coast by road or domestic flight. If you plan to travel from Istanbul to the port and complete the sea crossing on the same day, the port check-in time and the border crossing margin should be calculated together. Services may be seasonal, and not every port serves every island.
The general route logic is as follows: Ayvalık to Lesbos, Çeşme to Chios, Kuşadası to Samos, and Bodrum to Kos or Rhodes are the directions where ferry options are researched. These examples do not mean a direct departure from Istanbul; they show that you need to travel separately from Istanbul to the relevant port. The match between port and island should be confirmed on the operator's current timetable for the travel date.
When buying a ferry ticket, do not look only at the departure time. Passenger passport details, need to travel by car, luggage rules, port address, check-in closing time and the return connection are all part of the booking. Because weather and operator changes can affect a sailing, choosing a flexible plan rather than a very tight chain of connections on the return day is safer.
Athens flights suit distant islands and short holidays; ferries from the coast suit the eastern Aegean islands closer to Türkiye. The destination island and the total door-to-door time form the basis of the decision. Consider not only the ticket price but also the journey from Istanbul to the port, waiting time and the two separate border procedures.
| Route model | Suited to | Point to watch |
|---|---|---|
| Istanbul, via Athens, then island flight | Those going to distant islands such as Santorini, Mykonos, Crete or Corfu | Connections, baggage and domestic flight times |
| Istanbul, to an Aegean port, then ferry | Those wanting a sea crossing to Lesbos, Chios, Samos, Kos or Rhodes | Land transport to the port and seasonal sailings |
| Istanbul, via Athens, Piraeus, then ferry | Those who want to see Athens and change islands by sea | City transfer and port terminal |
For example, on a short Lesbos or Chios plan of a few days, travelling from Istanbul to an Aegean port may be a more natural route than a flight via Athens. On the other hand, for Santorini, going from Istanbul to a coastal port and then connecting through another island usually adds unnecessary connections. Also check our guide to visa on arrival and the island list for Greek islands before choosing a route; the visa type is as decisive as the transport.
The easiest ferry plan from Istanbul is to reach a port on Türkiye's coast and then cross to the island that port serves. In the eastern Aegean, Turkish-linked options may be seen for Lesbos, Chios, Samos, Kos and, at some times, Rhodes. It should not be assumed that every island has regular sailings from the same port; the route, date and operator should be checked together.
Ayvalık is a frequently researched starting point for Lesbos, Çeşme for Chios and Kuşadası for Samos. For Kos and Rhodes, connections from Bodrum or Marmaris may come up. These ports can be reached from Istanbul by bus, private car or domestic flight. When choosing the transport method, it matters whether the ferry departs early in the morning and what time you must be present at the port.
Those wanting to visit several islands can first cross from Türkiye to one island and then connect to the ferry network inside Greece. However, guaranteed onward connections between two separate tickets and two different operators may not exist. For this reason, to reduce the risk of missing the second ticket if the first sailing is delayed, a plan that stays overnight at each stop may be preferable to a very tight island chain on the same day.
There is no single fixed timetable for ferries and flights; when to check depends on the travel season, the island and the operator. Before booking, reconfirm the date, port and baggage conditions on the official timetable screen. Old seasonal times shown in search results should not be treated as the current schedule.
First set your outbound and return dates, then match the transport options from Istanbul to the port or airport. Staying overnight in the city where the ferry departs can reduce risk, especially on early morning sailings. On a flight, ask the airline whether the Athens connection is at the same airport, whether your baggage will be tagged through to the final destination, and what the ticket rules are in case of delay.
For current availability, port changes and cancellation terms, use the official operator channels such as Blue Star Ferries and SeaJets; for air connections, use the flight plan of the relevant airline. Our guide to getting to Santorini also explains how the choice between flight and ferry changes with island distance.
The passport and visa requirement for Turkish citizens entering Greece is assessed according to the travel document held and current regulations. Buying a ferry ticket does not replace a visa; a Schengen visa or a valid right of entry should be checked before planning the route. Where visa on arrival applies, it is valid only for authorised islands and conditions within the current programme.
Check the validity period of your passport, blank pages, travel health insurance and supporting documents using the current official announcements of the competent authorities. For islands not on the visa-on-arrival list, such as Santorini, Mykonos, Crete, Corfu or Zakynthos, separately check whether a Schengen visa is required. If you are planning a visa application, your hotel, transport and travel dates should be consistent with each other.
The visa decision belongs to the consulate. The check-in rules of the carrier and the entry assessment of the border officer are different matters, so a ticket or reservation alone does not guarantee entry to the country. To look at accommodation options for your travel dates, you can browse Orjinaltur hotel options and build your stay plan on the connecting islands accordingly.
A good island plan starting from Istanbul first chooses the island and the entry method, then brings transport, accommodation and the return connection together on one timetable. The safety of the return day is as important as the one-way transport. If this is your first trip, it is more controlled to start with a single-connection plan rather than a complicated route requiring two separate border and port changes in one day.
On a short three-night holiday, one nearby island such as Lesbos, Chios or Samos may be enough on its own. On a longer holiday it is possible to move from one island to another, but each new connection increases the risk of weather, cancelled sailings and baggage problems. If you are considering renting a car on the island, ask about your driving licence and whether the rental company allows the car to be taken off the island.
Consider the area where you stay in terms of access to the port or airport. Especially on early ferries, the transfer time from the city centre to the port can be as practical a criterion as the view from the hotel. On island-focused pages such as the Mykonos destination page, deciding accommodation and transport together offers a sounder starting point than simply searching for tickets.
Also consider your starting point in Istanbul when deciding the route. The time from the European side to the airport, or from the Anatolian side to the bus station or the Aegean direction, can vary with the hour of the day. On a night ferry plan you need to allow time waiting around the port, while on a daytime flight you need to arrive at the airport early. These details make the total travel time differ from the times printed on the ticket.
Keeping the transport chain simple on an island holiday reduces stress, especially on a first trip. A plan made up of one flight, one ferry and one transfer to accommodation is easier to manage when things go wrong than a plan involving three separate tickets, two ports and short connections. Even so, travellers on longer holidays who want to add Athens or a second island can build their own route by leaving a safety margin on every connection.
To plan your transport and accommodation for Greek islands from Istanbul together according to your travel date, you can ask Orjinaltur for current options and personalised booking support.

For most Greek islands, there is no regular direct ferry from Istanbul. The usual route is to reach a port on Türkiye's Aegean coast and take a ferry from there. Whether a sailing exists, which port it uses and what the timetable is should be checked on the official operator's screen.
For Santorini, flying from Istanbul to Athens and connecting to a flight from Athens to Santorini is usually the most direct air plan. As an alternative, a ferry from Piraeus port can be researched after arriving in Athens; the duration and sailings vary by date.
To go to Lesbos, a route from Istanbul to Ayvalık by road or by a suitable domestic connection can be used, followed by a ferry from Ayvalık port. Passport, visa, check-in and sailing conditions should be confirmed through official channels.
The entry condition depends on the travel document and the current rules. Visa on arrival applies only on authorised islands and under the conditions of the programme. For other islands, check with the official authorities whether a Schengen visa is required.
Check the departure port, check-in closing time, passport details, baggage and vehicle rules, cancellation terms and the return connection together. Since sailings can be affected by weather and seasonal conditions, rely on the official operator's information.
