If your vacation in Turkey lasts more than one week, then you probably want to go on some interesting excursion.
We recommend:
Boat trips are short and long.
A trip to Istanbul.
Istanbul is the most visited city in Turkey. (One would like to say the capital of Turkey, but the capital of Turkey is the city of Ankara.)
Istanbul has a very rich history. You should probably visit this city if you can afford it.
You can book a trip to Istanbul in advance, online. It will be a very interesting journey, we are sure.
