Istanbul is a city of over 13 million inhabitants, a maze of narrow streets, boulevards and bridges mixing modernism and historical heritage. Transportation seem a little complicated, but it’s not as incomprehensible as it looks like.
First the ” Istanbul Kart ” I didn’t found it the first day … you will find this card in bookstores or convenience store near a public transport station or in a IETT ticketmatics or counter that for myself i didn’t find anywhere in my first days on location . It will cost you TL 7 or TL 8 or TL 9 … whatever… the official price on IETT website is 6 Turkish Lira. In fact all prices in Istanbul varies according to the location you are and the mood of the trader and how much tourist you look like, I paid mine TL 8.
This card is empty on purchase, you must go to a public transit ATM and fill it . I spent 9 days in Istanbul with 25 TL (i walk a lot) . The price of transport is greatly reduced with the card, you get 40% off, so instead of TL 4 it’s TL 2,30 and the transfer are less expensive as you take them in a period of 2 hours. Without the card , you must buy plastic token at 4 TL a piece to enter public transport.
For basic tourism, the T1 line will be your daily routine. This tram goes from the Taksim – Kabatas funicular as far as pass the Theodosius II Wall and goes through the Grand Bazaar, Topkapi Palace and the duo Hagia Sophia and Blue Mosque. The Taksim – Kabatas funicular takes you to Taksim Square in the Beyoglu district near the historical Galata district.
