More internationally known as the former Six Flags Holland, Walibi World is a superb theme park with plenty of attractions for all ages.  Its star attraction is the amazing mega coaster Goliath, and complimenting this are fun rides like the former Superman: The Ride, now called 'Xpress'.  Walibi World is difficult to get to but can be done by taking a train to Lelystad from Schiphol Airport and then connecting with a bus straight to the park from that station.  All of the rides at Walibi World are well-maintained and are worth a go.
