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 Aquitaine to Compagnie des Alpes (back then : Grévin & Cie). Beginning of 2015, Compagnie des Alpes sold off the park again, this time to the Spanish group Aspro Parks. Compagnie des Alpes gave Aspro Parks a licensing agreement to use the name 'Walibi' for an additional 5 years. From 2021 on, the park changed its name to 'Walygator Sud-Ouest'.
