Overall safety
Istanbul is generally safe for tourists with standard urban precautions. The city is well-policed in tourist areas and violent crime against visitors is uncommon. The primary risks are city-specific and largely avoidable.
Taxi scams
Taxi overcharging is the most documented tourist problem in Istanbul. Tactics include 'broken' meters, route manipulation and offering a high 'fixed price' from airports and tourist sites. Always ensure the meter runs from the start; use the iTaksi or BiTaksi apps for upfront pricing and trip tracking. Keep small denomination lira for payment.
Bazaar & tourist area scams
Aggressive touting in the Grand Bazaar (carpet shops, jewellery stores) and Spice Bazaar is standard — a confident 'hayır teşekkürler' (no thank you) and walking on is the correct response. Do not follow strangers who 'just want to practice English' or offer hospitality — a known social-engineering approach.
Pickpocketing
Pickpocketing operates in the Grand Bazaar, along Istiklal Avenue (Taksim) and at major tourist sites. Use a crossbody bag, keep phones in inner pockets and stay aware in crowded transit.
Travel advice
Check current FCO (UK) or State Department (US) travel advisories before departure — the situation around major public gatherings and political events can change. For most tourists on most visits, Istanbul is an entirely manageable destination.
