Istanbul is an exotic port, unlike any other. Minarets rise into the sky, and the modern combines with the traditional.
The Blue Mosque, and the Aya Sofia are visually stunning, and the spice market is a feast for your senses. The tram is an easy way to get from place to place & is only a few blocks from the cruise port. You need to purchase a token to ride, but it only costs about $2 USD per trip. On every corner is a kebob restaurant, and baklava and turkish delight are available everywhere.
