Before Six Flags Fiesta Texas opened in 1992, the park used to be the site of a limestone quarry created in 1934.
The portion where Fiesta Texas is located was depleted in 1988 and the land was available for development.

A 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.

The concept plan and master plan were developed by FORREC International based in Toronto.
FORREC handed over a detailed design of the project to San Antonio-based architecture and engineering groups: Benham/Jones Kell and Pape Dawson.
Actual construction of the theme park took approximately 23 months, running from early 1990 to the park's opening in March 1992.
Construction of the theme park was overseen by a joint venture of two general contractors, Lyda Inc. of San Antonio and Manhattan Construction Company of Tulsa, Oklahoma.
The park had four theme sections; Crackaxle Canyon, Los Festivales, Spassburg and Rockville, along with a water park called, Ol' Waterin' Hole.
In its third season, 1994, Fiesta Texas added a new themed area, Fiesta Bay Boardwalk, with multiple new rides and attractions including a Ferris wheel, swinging ship, scrambler, and a roller-skating pavilion.

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.
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.
Also in 1999, Six Flags Fiesta Texas was awarded Amusement Today's Golden Ticket Award for Best Shows in the theme park industry.
The park continued to receive the award every year until 2008.

Six Flags Fiesta Texas announced the rename and expansion to its water park to White Water Bay in 2006, with the water park's largest expansion.

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 begin (for the first time in its history), operating at a year-round schedule.
Before 2019, Fiesta Texas and Six Flags Fiesta Texas both ran their operating seasons from March to the end of the year.
For the first time since 1994, Six Flags Fiesta Texas will be opening up its sixth new theme area to the park, DC Universe, which will include most of the already established DC Comics themed rides, along with the new ride to the park, The Joker Carnival of Chaos in 2019.

A day before the park's 28th anniversary (March 13, 2020), Six Flags suspended all operations across all their properties due to concerns of the COVID-19 pandemic.
During the time of closure, the park has donated 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.
