Wonder Woman Golden Lasso Coaster, Steel roller coaster in San Antonio, Texas, United States

The Wonder Woman Golden Lasso Coaster is a single-rail steel coaster at Six Flags Fiesta Texas in San Antonio, built by Rocky Mountain Construction. Its red track and supports with yellow rails form a 548.6 m circuit reaching 34.4 m, with a 30.5 m first drop at 90 degrees, a dive loop, a cutback and a corkscrew. A 113 ft chain lift climbs to a triangular red frame at the crest.

Rocky Mountain Construction built this facility, which opened on May 12, 2018, as one of two prototype single-rail coasters in the United States. The technology marked a new approach in roller coaster design with narrower tracks.

The coaster is themed to the DC Comics character Wonder Woman, and its red track with yellow rails echoes her costume. It was one of two prototype single-rail coasters to open in 2018, the other being RailBlazer at California's Great America, whose layout mirrors this one.

Participants must be at least 48 inches (122 centimeters) tall to ride the attraction. The facility operates three trains with eight single-rider cars each, reaching speeds of 52 miles per hour (84 kilometers per hour).

The facility uses a continuously moving station system where trains progress through loading zones while passengers board and exit. This approach reduces wait times and keeps operational flow consistent.
