Before Fiesta Texas opened in 1992, the site was part of the Redland Quarry which began operation in 1934. By 1988, the limestone in the portion where Six Flags Fiesta Texas is located was depleted and the land was available for development. The development team consisted of property owner
USAA Real Estate Company, a subsidiary of the USAA insurance company and
Gaylord Entertainment Company, a company that owned
Opryland USA, a theme park in
Nashville, Tennessee. When the initial ownership group began investigating a possible major theme park development in San Antonio, Texas, they faced significant competition in the Texas market. There were similarly established Six Flags parks in
Arlington and
Houston. Based on the competition, the development team believed the opportunity in San Antonio (an established regional leisure destination) was there and that the stable, slow growth direction of the theme park industry in the U.S. was in their favor.
Time Warner took over management and operations of Fiesta Texas in 1996 and added the Six Flags name to the park, while USAA remained as the sole owner. Six Flags Fiesta Texas added its third roller coaster, a
Vekoma Hurricane named
The Joker's Revenge, which opened to the general public on May 10 of the same year. It was the park's first roller coaster to go upside down and the first ride to be based on
DC Comics. The Joker's Revenge featured a funhouse queue line and trains that traveled backward through the course.
Premier Parks, which acquired the
Six Flags theme park chain from Time Warner, purchased Fiesta Texas from USAA in October 1998. In 1999, Fiesta Texas saw the biggest expansion ever in park history with more than 10 new rides and water rides, as well a rename of the water park to Armadillo Beach. With the infusion of new rides, the park saw its annual attendance increase by more than one million visitors. In March 2006, Six Flags Fiesta Texas expanded its water park and renamed it
White Water Bay. The rehab included a redesigned plaza, new food and merchandise facilities and four new waterslide attractions. The Six Flags company began the process of removing licensed theming company wide across its theme parks from attractions that the park had built in previous years. Six Flags Fiesta Texas had to rename and retheme seven rides as well as the kids theme area from Wiggles World to
Kidzopolis, all in time for the 2011 season. In 2019, the park for the first time in its history, operated at a year-round schedule. Before 2019, Fiesta Texas ran their operating seasons from March to the end of the year. In 2019, the park opened up a new theme area,
DC Universe, which included most of the already established
DC Comics themed rides, along with the brand new, Joker Carnival of Chaos. A day before the park's 28th anniversary (March 13, 2020), Six Flags suspended all operations across all its properties due to concerns of the
COVID-19 pandemic. During the time of closure, the park donated its food and supplies to a local hospital and food bank. On June 4, Six Flags announced the park would reopen on June 19 to members and season pass holders, and to the general public on June 22. On July 28, 2021, plans were announced for the park's 30th-anniversary celebration in 2022 which will begin with a New Year's Eve Kickoff Event. Plans include a retheme of the popular
Poltergeist roller coaster, a Celebrate 30 Night Show, food festivals, displays, a mini-museum, and a new B&M Dive Coaster,
Dr. Diabolical's Cliffhanger. The latter ride officially opened on July 30, 2022. ==Areas==
