The Valencia theme park Magic Mountain will remain open in 2007,although which company will run it is unclear. In a call to investors this morning, Six Flags CEO Mark Shapiro said the company has decided not to close Magic Mountain and redevelop the land for other uses. However, he did not say the company will not sell the park. “I can’t underscore this enough: Magic Mountain will be open for business in 2007 and will stay open for the foreseeable future, no matter who owns it,” Shapiro said in a call to investors. Six Flags this summer announced it was milling over plans to Magic Mountain in a bid to reduce debt and realign its theme parks with a more family-friendly image. It was suspected the property, just west of the Golden State (5) Freeway, could be sold to a real estate developer. The New York company operates 30 parks across the county.
