First, the thing that catches everyone out
Sabiha Gökçen sits in Pendik, on the Asian side of Istanbul. The postcard half of the city — Sultanahmet, Taksim, Galata, Beşiktaş — is on the European side, across the Bosphorus.
That single fact governs everything below. A trip to Kadıköy is a straightforward run down the Asian coast. A trip to Sultanahmet means a bridge or a tunnel, and at the wrong hour the crossing takes longer than the rest of the journey put together. When you compare options, compare them for your side of the water.
Havabüs: the one-vehicle option
Havabüs is the airport coach service, and for most arrivals it is the sensible public option. You board at the terminal, put your luggage in the hold, and get off at the other end. No stairs, no turnstiles, no changes.
Buses leave from directly outside the terminal building and accept cash, credit card and İstanbulkart on board.
| Destination | Fare | Side of the city |
|---|---|---|
| Kadıköy | ≈₺230–270 | Asian |
| Yenisahra | ≈₺230–270 | Asian |
| Taksim | ≈₺370–440 | European |
Where Havabüs actually drops you
This matters more than the timetable. The Taksim service ends on Abdülhak Hâmit Caddesi near Taksim Square, not at your hotel door. If you are staying in Sultanahmet, Karaköy or Beşiktaş, you are getting off at Taksim and taking a taxi or the funicular onwards, with your bags.
The Kadıköy service ends at the ferry terminal area on the waterfront, which is genuinely useful if you are staying on the Asian side or want to continue by ferry.
- Kadıköy departures begin around 04:15 and run through to roughly 23:15.
- Returns from the airport towards Taksim run from about 06:30 until midnight.
- Departure frequency is broadly every 30 to 45 minutes, tightening at peak times.
- Allow three hours before your flight when travelling in the other direction.
M4 metro: cheapest, if you are going to Kadıköy
M4 runs straight from the airport to Kadıköy on the Asian shore, and at one İstanbulkart fare it costs a fraction of everything else. The station sits inside the airport complex, signposted from arrivals.
The journey runs about 45 to 50 minutes across roughly 21 stops, with trains every 4 to 8 minutes during the day and every 8 to 12 in the evening.
The catch is the far end. M4 terminates at Kadıköy on the Asian side. For the European side you continue by ferry across the Bosphorus, or change to Marmaray at Ayrılık Çeşmesi and cross underneath it. Either way that is a second leg, with luggage, and possibly a third once you reach the other shore.
You need an İstanbulkart
Istanbul's public transport does not take contactless bank cards on most lines. You buy an İstanbulkart from a machine at the station, load credit onto it, and tap.
The standard single fare rose to ₺46.20 on 20 July 2026, in the same UKOME decision that raised taxi tariffs by 10 percent. Transfers within a set window are discounted rather than charged in full, so a metro-plus-ferry journey costs less than two separate taps.
Putting the options side by side
The honest summary: if you are travelling light, arriving in daylight and staying on the Asian side, the M4 is excellent and nothing else comes close on price. If you are landing at 2am with two suitcases and a hotel in Sultanahmet, public transport is not really competing.
| Cost | Time | Changes | Late night | |
|---|---|---|---|---|
| M4 metro to Kadıköy | ₺46.20 | 45–50 min | None | No — stops ~midnight |
| M4 + ferry/Marmaray to Europe | ≈₺75–95 | 90–120 min | 1–2 | No |
| Havabüs to Kadıköy | ≈₺230–270 | 60–75 min | None | Yes, overnight |
| Havabüs to Taksim | ≈₺370–440 | 90–120 min | None to Taksim | Yes, overnight |
| Metered taxi | Meter + tolls | 55–90 min | None | Yes |
| Private transfer | Fixed, from €55 | 55–80 min | None | Yes |
Which one to actually pick
- Staying in Kadıköy, Ataşehir or Pendik, arriving in daylight, light bags — take the M4.
- Staying around Taksim or Beyoğlu, arriving in daylight — Havabüs to Taksim, then a short taxi.
- Arriving after midnight — the metro is closed, but the E-10 city bus to Kadıköy runs around the clock.
- Travelling with children, a cruise sailing, or more than one large case each — the change-free options are worth the difference.
And the option most guides leave out
Around ten municipal bus lines also serve Sabiha Gökçen, and they almost never get mentioned. They cost the same ₺46.20 İstanbulkart tap as the metro, reach parts of the city the M4 does not, and — crucially — the E-10 to Kadıköy runs twenty-four hours a day at fifteen-minute intervals.
That makes the bus network the real answer for a late landing, which at a low-cost hub like Sabiha Gökçen is a common situation. The trade is that city buses have no luggage hold and sit in ordinary traffic.
Going deeper on each option
This page is the overview. Each mode has its own guide with timetables, fares, where to stand and what goes wrong:
- The M4 metro — route, 23 stations, opening hours and the Bosphorus problem.
- The Havabüs coach — stops, night service, and the free ride for Türk Telekom Prime customers.
- Municipal buses — all ten lines, the 24-hour E-10, and why SG-1 is not the Havabüs.
- İstanbulkart — buying one at the airport, sharing it, and what a journey costs.

Frequently asked
How do I get from Sabiha Gökçen to Taksim by public transport?
The Havabüs coach runs directly to Taksim for roughly ₺370–440 and takes 90 to 120 minutes depending on traffic. The cheaper alternative is the M4 metro to Kadıköy, then a ferry or Marmaray across the Bosphorus, which costs far less but involves at least one change with your luggage.
How much is the Havabüs from Sabiha Gökçen?
Roughly ₺230–270 to Kadıköy or Yenisahra and ₺370–440 to Taksim. Published figures disagree because the fare rose during 2026, so confirm with the operator before you travel. You can pay on board with cash, a credit card or an İstanbulkart.
Is there a metro from Sabiha Gökçen airport?
Yes. The M4 line runs from a station inside the airport complex to Kadıköy on the Asian side, taking about 45 to 50 minutes across roughly 21 stops. A single İstanbulkart fare is ₺46.20.
Does the Sabiha Gökçen metro run at night?
No. The M4 operates roughly from 06:00 to midnight. If you land later than that, your options are the Havabüs coach where it is still running, a metered taxi, or a pre-booked transfer.
Do I need an İstanbulkart at Sabiha Gökçen?
For the metro, yes — most Istanbul lines do not accept contactless bank cards. Buy the card from a machine at the station and load credit before you tap in. Havabüs also accepts İstanbulkart, as well as cash and credit cards.
Which side of Istanbul is Sabiha Gökçen on?
The Asian side, in Pendik. Sultanahmet, Taksim, Galata and Beşiktaş are all on the European side, so those journeys involve crossing the Bosphorus by bridge, tunnel or ferry.
