Tower of Terror is a roller coaster in Gum Tree Gully at Dreamworld. It's worth seeing on a time-permitting basis. The minimum height to ride is 48 inches.
Very similar to Six Flags Magic Mountain's" Superman; the escape. Its a 'L' shaped track, where you are shot up the track, and freefall backwards. It was the first ride in the world to break the 100mph mark, first blasting off on January 23 1997, about 3 months before the Magic Mountine Ride and shares the same operating speed as the American version. This ride also has the added attraction that the line is rarly longer then 10 mins in off peak times.
