Six Flags America

Six Flags America was a 131-acre (53 ha) amusement park in Woodmore, Maryland, United States, within the Washington, DC, metropolitan area. It had a water park named Hurricane Harbor Maryland. Founded as a wildlife center in 1974 by Ross Perot, ABC television operated the park as a drive-through safari called The Largo Wildlife Preserve, from 1974 until its closure in 1978. The property was bought by Jim Fowler's Wild Kingdom; thereafter, the site was gradually converted from a wildlife preserve into a theme park named Wild World. In 1992, the park was renamed Adventure World after being acquired by Premier Parks. The park was rebranded as the tenth Six Flags park, after Premier Parks acquired Six Flags Inc., and adopted its name in 1999; the name-change to Six Flags America—and all associated IP and theming—was unveiled for the park's 1999 operating season. Following a 2024 merger between Six Flags and Cedar Fair, the park permanently closed on November 2, 2025, as part of the new Six Flags company's portfolio optimization program. Six Flags sold the park's 515-acre (208 ha) site to Thirty Five Ventures, a firm owned by Kevin Durant, and TPA Group in April 2026 in order to pay down corporate debts. The site is planned for mixed-use redevelopment.
