Six Flags Fiesta Texas, Theme park in San Antonio, United States

Six Flags Fiesta Texas is an amusement park in northern San Antonio, Texas, built on the site of a former quarry and home to twelve roller coasters and many other rides. The park is divided into themed sections representing different cultural influences in the state, with live entertainment stages and dining facilities throughout.

The site was part of the Redland Quarry, which began operation in 1934; by 1988 its limestone was depleted and the land was available for development. Construction ran from early 1990 to the opening on March 14, 1992, as a musical show park. Time Warner took over management in 1996 and added the Six Flags name, while USAA remained sole owner.

The park was conceived as a destination musical show park centred on the musical culture of Texas, and live shows became its hallmark: it won Amusement Today's Golden Ticket Award for Best Shows every year from 1999 to 2008. Its five themed areas are Los Festivales, Crackaxle Canyon, Spassburg, Rockville and Fiesta Bay Boardwalk, added in 1994 with a Ferris wheel, swinging ship, scrambler and roller-skating pavilion.

The park opens year-round with operating days varying by season, and offers restaurants and souvenir shops in every themed area. Visitors should wear comfortable shoes since the grounds are large and some sections include slopes and stairs.

The Iron Rattler roller coaster uses the natural limestone quarry walls as part of its track and runs along the exposed rock faces. Some rides sit below the original ground level and move through the depressions of the old quarry.
