Hydropolis water park is found on the north coast of
Corfu close to
Acharavi, it’s just under 40km from the capital which would take around an hour in a car or taxi.
Hydropolis is a relatively small park but has a good selection of slides, a lazy river and other games and entertainment too. There are sunbeds available throughout the park that are free to use, food and drink is available on site and they also offer all inclusive days on Mondays and Thursdays.
As of 2018 Hydropolis was only open to guests of the
Grecotel Costa Botanica hotel so if you want to visit you'll have to stay there.
If you are a fan of water parks and going to Corfu then you can always try
Aqualand.
