Is Istanbul Safe?

Yes, Istanbul is a safe city for tourists, and Turkey, in general, is considered safe for visitors. Locals are friendly and welcoming, and Istanbul is one of the most visited cities in the world.

While petty crime like pickpocketing can happen in crowded areas, violent crime against tourists is rare.

✔ Tourist areas are well-patrolled, and major landmarks like the Hagia Sophia, Topkapi Palace, and Grand Bazaar have a visible security presence.
✔ Taxis and public transportation are safe, but it’s best to use official taxis or ride apps like BiTaksi to avoid scams.
✔ If you’re a solo female traveler, Istanbul is generally safe, but as in any major city, it’s good to stay aware, avoid dimly lit streets at night, and dress modestly when visiting mosques.

Getting Around Istanbul

Istanbul is a massive city, but getting around is easy thanks to its efficient transportation system. Whether you prefer trams, buses, ferries, or taxis, there are plenty of ways to navigate the city.

✔ Istanbulkart – The Istanbulkart is a must if you plan to use public transportation. It works on trams, metros, buses, and ferries, and it will save you money compared to buying single tickets. You can purchase and reload it at kiosks and metro stations.

✔ Trams & Metro – The T1 tram line is the best way to explore Istanbul’s old city, with stops near Sultanahmet, Grand Bazaar, and Eminönü. The M2 metro line is useful for getting around newer areas like Taksim and Levent.

✔ Ferries – Istanbul’s Bosphorus ferries are a scenic and affordable way to cross between Europe and Asia. Ferries run from Eminönü, Karaköy, Beşiktaş, Kadıköy, and Üsküdar, giving you amazing water views of the city.
