I recommend you to visit Adaland when you are in Kusadasi or near to Kusadasi. It's the largest park of the Europe. It has waterpark, dolphinpark and seapark inside the Adaland. First of all it is a very clean place. Staff working there is so kind and helpful. In waterpark you should join to Rafting and also rain dance activity. In Dolphinpark there is Dolphin Show also swimming. Seapark is the relaxing place with many types of sea creatures.
