Iron Rattler, Steel roller coaster at Six Flags Fiesta Texas, San Antonio, US

Iron Rattler is a hybrid roller coaster at Six Flags Fiesta Texas in San Antonio that climbs 179 feet (54 meters) and travels along a limestone cliff face. The ride combines steel rails with wooden elements in its overall structure and reaches speeds up to 70 miles per hour (113 kilometers per hour).

The original Rattler opened in 1992 as a wooden roller coaster at the park. In 2013, the ride was completely rebuilt with a steel track system, becoming a hybrid coaster that maintains the same general layout.

The ride's two trains are themed to rattlesnakes and built by Gerstlauer, each with six cars seating four riders in two rows of two. The name carries over from the wooden Rattler it replaced, and the coaster stands in the Western-themed Crackaxle Canyon area beside Road Runner Express and The Gully Washer.

Iron Rattler sits in the Crackaxle Canyon area, next to Road Runner Express and The Gully Washer. Riders are held by a lap bar and a seat belt in the two six-car Gerstlauer trains, each car seating four in two rows of two. The layout ends in a tunnel near the base of the quarry wall with fog and lighting effects.

Iron Rattler's zero-g roll was the first inversion of its kind on a hybrid wood-and-steel coaster, and it sits atop the quarry wall. The ride's tunnel passes through a former limestone mine near the base of the cliff.
