go to Antalya
waterfalls-kur?unlu :
Cleopatra Beach, Alanya Turkey :
and the Hotel in Antalya called Titanic ,it looks like a nice place
then there is a resort in Antalya,Turkey but I dont know what its called :S

blue mosque is in istanbul.. it is amazing, but istanbul is not a good place for water adventures.. you can go to Alanya ( Koprulu Kanyon) for Rafting. It is really cool..

you can also go to Kas (in Antalya) for diving..

Istanbul is good for cultural activities..

For other water rides like jet ski or sth, you can find it in almost all the hotels beaches..

I advise you to go to Bodrum.It is a wonderful place to visit.Besides, there are many water activities and stoneboats for kids.It is one of the best choice for the kids to entertain and have a good time.For adults, there are many activities as the kid's.You can sunbath,eat delicious deserts,drink fresh lemonade,have a good time in night clubs in Türkbükü(It is heart of Bodrum).I recommend you to go to a hotel called 'Baia'.I went there 3 times and liked it very much.I am sure You won't regret.Have a good time in Turkey=)

Marmaris has a new waterpak. but i stayed in alitinkum (which i do not recommend. it was horrible, and whilst there i took a trip to kushadasi waterpark which was amazing! the best ever i really want to go back. so i recommend marmaris which has lovely culture and nightclubs, things 4 the kids. it has everything. either there or kushadasi. im going back to marmaris now in june 4 the 13th time

there's a waterpark called adaland in kusadasi. it's a lot of fun, there's tons to do and there are nice oceanfront resorts near by.
