In 1998 Premier Parks purchased the park. At the time Premier Parks also owned Six Flags Corporation. In 2000 the Premier Parks name was dropped in favor of the more popular Six Flags brand name.
Six Flags operated the park until early 2004 when Six Flags sold their European parks (excluding their small portion of Warner Bros. Movie World in Madrid, Spain) to Palamon Capitol Partners who now operate the parks under the Star Parks Europe name.
In the spring of 2006 Star Parks sold Walibi Rhône-Alpes to Grévin & Cie.
