Jersey Devil Coaster is a single-rail steel roller coaster at Six Flags Great Adventure in Jackson Township, New Jersey, themed around the legendary creature said to haunt the nearby Pine Barrens. Built by Rocky Mountain Construction and designed by Alan Schilke, it opened to the public on June 13, 2021, after a year-long delay caused by the COVID-19 pandemic.
At 130 feet tall and reaching speeds of 58 mph, it debuted as the world’s tallest and fastest single-rail coaster, a title that reflected RMC’s growing reputation for pushing this relatively new coaster format to new extremes. It held that record until 2022, when Six Flags Magic Mountain’s 131-foot Wonder Woman Flight of Courage took the title of tallest single-rail coaster, but Jersey Devil remains one of the tallest and fastest examples of the format. The ride was also the 13th coaster added to Six Flags Great Adventure’s lineup, a number the designers wove into the ride’s theming.

The Ride Experience
Riders board one of four trains, each seating 12 people single-file in a narrow, straddle-style car that runs along a single steel rail rather than the usual pair of tracks. After a 130-foot lift hill, the ride plunges down a steep drop before launching into three inversions, including a dive loop, a zero-g stall, and a zero-g roll, all delivered with the twisting, off-axis sensation that RMC’s raptor-track single-rail coasters are known for.
The layout packs a lot of airtime and rapid direction changes into its 3,000-foot circuit, a hallmark of RMC’s design approach. The coaster’s queue also nods to park history, incorporating a statue salvaged from El Diablo, a short-lived spinning coaster that operated at the park from 2015 to 2017.
Theming and Records
The ride’s Jersey Devil branding leans into New Jersey folklore, with the number 13 appearing repeatedly in its design, from its 130-foot height to its June 13 opening date and its status as the park’s 13th roller coaster. It was the first new coaster built at Six Flags Great Adventure since The Joker debuted in 2016.
At launch, Jersey Devil Coaster held the record as the tallest and fastest single-rail roller coaster in the world, cementing RMC’s raptor track as a format capable of scaling up beyond the smaller single-rail models the manufacturer had previously built. Six Flags Magic Mountain’s Wonder Woman Flight of Courage surpassed its height record in 2022, but Jersey Devil remains a benchmark ride for the single-rail format.
