there's a small one behind burger king. the main one is called waterplanet, about 30-40 mins coach journey, can't remember how much we paid for the trip but it wasn't much and was a great day out!!

the aquapark in the centre is nice..and the big one is as laura said is outside of town..near avsallar
the grand kaptan is in tosmur..about ten minutes from alanya centre by regular dolmuş..costs a lira and will stop outside the aquapark in the centre of town.

so theres 2 water parks in alanya

no ..one in the town..not too big..but nice..and one about 10 miles outside...from tosmur about 15 miles..there are regular coach trips to it..but the town one is easy to get to by local little bus..top of the street from the Grand kaptan..
also on the Dimcay river almost all the places there(picnic restaurants..not expensive) have water chutes etc for kids..big and small!!

The one in Town beside burger king is not huge but fine for a day out, we spent 2 days there last year and had a great time.

You get a card and top it up when you get in to pay for food and drinks,the food/drink is reasonably priced.

There's a huge swimming pool inside aswell with loungers if you don't want to go on any slides.

Also there's a turkish bath beside it which we went to after we had been in the water park that was great aswell.
