When it's 6:00 PM in Köln (Cologne), it's 7:00 PM in Istanbul.
German passport holders enter Turkey visa-free for up to 90 days within any 180-day period. Your passport must be valid for at least 6 months from entry. No eVisa, no fee, no advance registration needed. You get stamped in at the border and that is it.
The 90-in-180 rule is strictly enforced. Turkey counts all entries cumulatively. If you spend 90 days and leave, you must stay out for 90 days before returning. Overstaying results in a fine and potential entry ban. For longer stays, apply for a residence permit within the first 90 days through the e-ikamet system at e-ikamet.goc.gov.tr.
M11 Metro to Gayrettepe takes about 35 minutes (₺60–70 with Istanbulkart) with connections to M2 (Taksim) and M7. Runs from 5am to midnight. The metro bypasses O-7 motorway traffic, which is frequently heavy into the city.Havaist buses serve major destinations including Taksim, Kadıköy (European and Asian sides), and Sabiha Gökçen Airport (₺50–80). Taxis from arrivals are metered; insist on the meter. Journey to Sultanahmet or Taksim costs ₺400–700 depending on traffic. Rental cars available. Hotel shuttles common for business hotels near the city.
The new airport sits 35km from central Istanbul on the European side, slightly inland and exposed to Black Sea weather systems. Winters (December–March) are cold (0–8°C) with fog, rain, and occasional snow. Snow on the exposed plateau is more likely than in the city. Ice on taxiways causes delays.
Summers are warm (25–32°C) with dry, reliable weather. Spring and fall bring heavy rain and strong northerly winds (Poyraz) that can affect smaller aircraft. Fog is the primary low-season disruption risk. The airport's elevated position makes it slightly windier than the Atatürk site it replaced.
