CanevaWorld contains two theme parks. Aquaparadise features plenty of exhilarating water slides, while Movieland has stunt-packed action shows. Movieland stays open until 11pm for much of August, and also opens some winter weekends; check the website for details.
There's a wide range of combined and two-day ticket options. You can also take in an evening medieval banquet , of sorts (adult/reduced €30/20).
