If you’re traveling from India, you will need to fly to the Ataturk International Airport, located about 30 minutes from the heart of the city. There are direct flights to Istanbul from both Mumbai and New Delhi. Upon arrival, avoid the hecklers and go straight to the taxi queue outside the airport. Istanbul is famous for its mind-bending traffic and you shouldn’t be surprised if this 30 min drive snowballs in to a three-hour marathon!
While in Istanbul, the best way to experience the city is on foot. You may also use Istanbul’s famous old-world street cars to travel short distances on the European side.
Indian nationals need to apply for a tourist visa. However, if one has a valid Schengen, USA, UK, Ireland visa or residence permit, they may get a single-entry e-Visa valid for one month. I used my US visa to enter Turkey. The process was smooth, and I was not asked any questions at immigration.
