RailBlazer, Steel roller coaster at California's Great America, Santa Clara, United States.

RailBlazer is a single-rail steel roller coaster at California's Great America in Santa Clara, California, built by Rocky Mountain Construction. Its chain lift and 90-degree drop both stand 106 feet (32 m) tall, and the layout holds three inversions, reaching 52 mph (84 km/h). The trains are shaped like all-terrain vehicles, and large rocks and a pool of water sit beside the track.

California's Great America announced RailBlazer on August 16, 2017, with a groundbreaking ceremony and a simulated POV video. The coaster opened to passholders on June 9, 2018, and to the public five days later. It was one of two prototype single-rail coasters to open that year, alongside the Wonder Woman Golden Lasso Coaster at Six Flags Fiesta Texas, whose layout mirrors RailBlazer's.

RailBlazer is themed to California State Route 1 as an off-road adventure around the San Francisco Bay Area and central coast. Large rocks and a pool of water stand beside the track, and the queue interacts with the water. The trains are built to resemble all-terrain vehicles, with handlebars, a grille, headlights and a bumper.

The queue winds past large rocks and a pool of water, and the station sits at the end of that path. The ride climbs a 106-foot chain lift before the 90-degree drop into a tunnel, so the first drop is visible from outside the entrance. Riders board trains built to look like all-terrain vehicles, with handlebars, grille, headlights and bumper.

RailBlazer was one of two prototype single-rail coasters to open in 2018; its twin, Wonder Woman Golden Lasso Coaster at Six Flags Fiesta Texas, uses a mirror-image layout. The trains are built to resemble all-terrain vehicles, with handlebars, a grille, headlights and a bumper.
