This compact water park is in Anopolis, about 12km east of Iraklio. While it's certainly seen better days, it still offers plenty of fun on a hot summer day. Most attractions are geared to the pre-teen set, but a few (like the Kamikaze dark tunnel and the Hydro Tubes & Free Fall) provide even grown-ups with proper thrills.
Some attractions have height and weight restrictions. Tickets are 15% cheaper when booked online.
