Rules in force · 8Cobbled slopes in Sultanahmet, Galata and Karaköy defeat …
  • Türkiye (Turkey) ↗Check whether your passport is visa-exempt; if it is not, apply only at evisa.gov.tr — lookalike sites charge extra and some sell nothing.
  • Türkiye (Turkey) ↗At mosques cover shoulders and knees, take shoes off at the door, and women carry a headscarf; stay out during prayer times.
  • Türkiye (Turkey) ↗Taxis must run the taximeter; refuse flat quotes, or book through BiTaksi or Uber so the ride is logged.
  • Türkiye (Turkey) ↗Carry lira in small notes for tea, markets, tips and toilets; prices move with inflation, so treat every printed price as dated.
  • Türkiye (Turkey) ↗Do not take stones, coins or tiles from ancient sites, and export no antiques without a museum certificate; travellers have been detained at airport customs.
  • Marmara ↗Ferries to the islands and across the Bosphorus run less often in strong wind; check the last boat before you cross.
  • Istanbul ↗Cobbled slopes in Sultanahmet, Galata and Karaköy defeat suitcases: bags go from the car to the door, never on a walk or a tram.
  • Istanbul ↗Trams, metro, buses and public ferries all take the Istanbulkart; buy one at a kiosk on arrival and load it with lira.
