Pendik station, Türkiye

Yes, the railway hub is set rather far from downtown, about 35 km (40 mi) away. But don't worry, as the transport system of Istanbul is very well-developed, are reaching the city center from the station is not a problem at all.

The easiest way is, of course, to get a taxi, but if you are considering only public transport connections - get ready to walk for a bit. There is an iDO YHT Gar bus stop, located about 1 km (0.62 mi) from the station's building (you need to walk towards the sea). There, you can catch an E-9 bus that goes directly to the airport. But at the moment, a new metro line, M10, that will be a direct link between the Pendik Station and Sabiha Gokcen Airport, is under construction.
