Hi Sine
There is a water park near tsivili that has quite good reviews, look on http://www.justzante.co.uk under excursions.

Hi plumbblonde,

Thanks for the tip - I had a look at the site and the park looks really good!

Hi, We went to Zante about 18 months ago and there is a waterpark. It's not huge but has a good selection of slides that range in age. More scary for the older ones and slower ones for the kids. The are also tandem inflateables as well. There is a lazy river which is lovely as it just takes you round on an inflatable. We were there in August and there were plenty of sunbeds still vacant. We had a taxi there from Argassi arranged by the hotel, i can't remember how much but i know it wasn't expensive. Hope this is of help.
