BIO: CEST · IST: +03
When it's 6:00 PM in Bilbao, it's 7:00 PM in Istanbul.
Spanish passport holders enter Turkey visa-free for up to 90 days within any 180-day period. Your passport must be valid for at least 5 months from the date of entry (not 6, Turkey is specific about this). No eVisa, advance application, or fee is required. You get stamped in at the airport.
The 90-in-180-day rule is enforced strictly. If you stay 90 consecutive days, you must leave Turkey for 90 days before re-entering. Breaking the stay into shorter trips within the 180-day window is fine as long as the total does not exceed 90 days. Overstaying triggers entry bans ranging from 1 month to 5 years depending on the length of the overstay.
Turkey is not in the Schengen zone or the EU. Flights from Spain go through full passport control on both departure from Turkey and re-entry to Spain. Turkish immigration does check the stamp dates in your passport, so do not lose track of your 90-day count if you make multiple trips.
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.
