Istanbul tours and excursions
The best way to get those famed Istanbul skyline views is by boat and Bosphorus Strait Cruises are popular among tourists. Şehir Hatları (sehirhatlari.com.tr) is a ferry company offering Bosphorus tours.
There are many walking tours available.
A cluster of nine islands southeast of Istanbul is serviced by a number of ferries from Istanbul. No cars are allowed on these islands so rely on bicycles or horse-drawn phaeton carriages to get around. Büyükada is the largest island and worthy diversions include the former summer house of Leon Trotsky and Aya Yorgi Church.
The drive from Istanbul to Gallipoli Peninsula is about five hours but for many, the long journey is worth it to pay their respects at the WWI battlefield sites (now one of Turkey's major historical national parks) which were the scene of one of WWI's most famous campaigns.
