No sorry julieross,the nearest water park and only water park on ibiza is in playa denbossa,its not that far though and you can book excursions from es cana,the panorama offices next to zodiac apartments is about the cheapest option.

(there used to be one but that was years ago)

there is actually another water park in portinatx

its not exactly on the same scale as playa den bossa one.... when we went past it a few weeks ago the water at the bottom of the slides looked distinctly dodgy (i cant remember whether its been open the last few years as we rarely go up to portinatx in the summer)

the one in bossa is behind space - we went a few years ago with some friends kids and i dont know who enjoyed it more - the kids or the adults

Definatley nothing in Es Cana but we visited the one in Play d'en Bossa last year and it was loveley, very clean with loads of rides for the little and big kids and even a parrot show to boot.
