Twisted Colossus: Height, Records, Best Seat & Stats

Twisted Colossus doesn’t just loop — it races itself. Opened on May 23, 2015, this Rocky Mountain Construction hybrid at Six Flags Magic Mountain in Valencia, California transformed the park’s beloved 1978 wooden icon into a nearly-one-mile Mobius loop that sends two trains chasing each other through the same continuous track over and over again. At 4,990 feet it was the longest hybrid coaster in the world at its debut.

But raw length isn’t what makes enthusiasts rank it among the best steel coasters in North America — it’s the relentless ejector airtime, a prolonged inverted stall, and the heart-stopping near-miss where two trains pass so close their riders can reach toward each other, the famous ‘high five.’ This guide covers the exact height requirement, how rough it actually rides, which seat and row to pick, exactly where records stand today, and what became of the original wooden Colossus it was built from.

Quick Answer

Twisted Colossus is a Rocky Mountain Construction (RMC) hybrid coaster at Six Flags Magic Mountain in Valencia, California, in the park’s Screampunk District. It runs a single 4,990-foot Mobius loop of I-Box steel track, dueling two trains through a Top Gun Stall inversion and the iconic ‘high five’ near-miss at up to 57 mph, with a 48-inch height requirement and a ride lasting about 3 minutes 40 seconds.

It opened in 2015 as the world’s longest hybrid coaster; RMC’s own Steel Vengeance at Cedar Point has since measured longer by track length, though Six Flags still markets Twisted Colossus with that claim and it remains one of the longest hybrid coaster rides by duration and the only Mobius-loop dueling hybrid in the world.

Ride Stats at a Glance

Park: Six Flags Magic Mountain, Valencia, California, in the Screampunk District. Manufacturer: Rocky Mountain Construction (RMC). Designer: Alan Schilke. Opened: May 23, 2015. Height: 121 feet. Drop: 128 feet at 80 degrees. Top speed: 57 mph. Track length: 4,990 feet. Inversions: 2 (a Zero-G Roll and the Top Gun Stall). Ride duration: approximately 3 minutes 40 seconds.

Height requirement: 48 inches, lap-bar restraint. Trains: four 6-car trains built (24 riders each, 2-across, 2 rows per car), with up to three running at once depending on staffing and crowd levels. Hourly capacity: roughly 800 to 1,000 riders per hour when multiple trains are dispatching. Thrill level: high — Six Flags rates it among its most intense coasters, driven by steep drops, sustained airtime, and forceful transitions rather than tight, snapping turns.

Records: What Twisted Colossus Held Then vs. Now

When it opened in May 2015, Twisted Colossus was the longest hybrid roller coaster in the world at 4,990 feet of track, and Six Flags still promotes it with that title today. By measured track length, though, RMC’s own Steel Vengeance at Cedar Point — which opened in 2018 at roughly 5,740 feet — has since surpassed it, so Twisted Colossus is best described as a former record holder rather than the current one.

It still holds distinctions no other coaster does: it’s RMC’s only Mobius-loop hybrid and the only dueling hybrid coaster in the world, since the ‘racing’ effect comes from two trains sharing one continuous circuit rather than two separate tracks. Its roughly 3-minute-40-second ride time also ranks among the longest of any hybrid coaster anywhere, and it has placed in Amusement Today’s Golden Ticket Awards rankings of the world’s best steel coasters in multiple years since its debut.

Where to Find It: Location in the Park

Twisted Colossus is located in Six Flags Magic Mountain’s Screampunk District, an industrial-steampunk-themed area of the park. Thanks to its 121-foot lift hill and sprawling wooden support structure, it’s visible from much of the surrounding midway, making it easy to spot even before you reach the queue.

The Original Colossus: From Wooden Icon to RMC Hybrid

The original Colossus opened June 29, 1978, designed and built by International Amusement Devices. At debut it was billed as the world’s tallest and fastest roller coaster and the first with two drops over 100 feet — a genuine landmark that helped put Magic Mountain on the map for coaster enthusiasts.

After 36 years of operation, Six Flags closed the wooden Colossus on August 16, 2014, and announced its transformation into an RMC hybrid just two weeks later. Rocky Mountain Construction retained most of the original wooden support structure but replaced the wooden rails entirely with its I-Box steel track technology, reopening the ride as Twisted Colossus on May 23, 2015.

The Mobius Loop: How the Dueling Actually Works

Unlike a traditional racing coaster with two parallel tracks and two separate stations, Twisted Colossus uses a single continuous track in a Mobius loop configuration — there is only one station. A train dispatches, travels through the green half of the layout, crosses over to the blue half, and completes the full circuit before returning to the same station. Every rider experiences both halves of the ride in a single trip.

The dueling effect happens because a second train dispatches while the first is still mid-ride. When timing aligns, the two trains arrive at the high five and the Top Gun Stall simultaneously, creating the sensation of a side-by-side duel through the most dramatic moments on the course. Dueling isn’t guaranteed on every cycle — it requires two trains running on a coordinated interval, which depends on operational conditions and staffing. Busier days with higher throughput and more trains running make simultaneous encounters more consistent.

The High Five and the Top Gun Stall

The high five is the ride’s most photographed element. Both halves of the track bank steeply toward each other at roughly 90 degrees, and the two trains pass in extremely close proximity — close enough that riders instinctively reach out toward passengers in the other train. It was one of the first elements of its kind in North America when Twisted Colossus opened, and it remains one of the most visually striking near-miss moments in the industry.

Immediately after the high five, the green track launches into the Top Gun Stall: a zero-gravity inversion where the train rolls upside down and slows at the apex, leaving riders suspended in prolonged hangtime. At that same moment, when dueling is active, the blue track runs directly underneath, so stalled riders look down at another train of passengers being launched through violent ejector airtime below them.

Height Requirement and How Rough It Rides

Riders must be at least 48 inches (122 cm) tall, standard for a high-thrill hybrid coaster and lower than most launch coasters at the park. Restraints are a simple lap bar with a zipper pouch for loose items (added in a late-2018 retrofit), so larger riders generally fit comfortably compared to over-the-shoulder harnesses, and there’s no maximum-height restriction to worry about.

In terms of feel, Twisted Colossus rides noticeably smoother than a traditional wooden coaster because RMC’s I-Box steel rail eliminates the rattle and lateral jackhammering that plagued the original 1978 Colossus. What it doesn’t eliminate is intensity: the 128-foot drop and the string of airtime hills that follow deliver strong, sustained negative g-forces, and the Top Gun Stall adds real hang time upside down. Riders sensitive to strong airtime or inversions should expect this to be one of the more physically demanding rides at Magic Mountain, closer in intensity to New Texas Giant or Iron Rattler than to a family wooden coaster.

Best Seat: Front Row vs. Back Row

Back row delivers the strongest sensations on Twisted Colossus: the whip-crack effect through each airtime hill amplifies the ejector-air feeling, and the extra beat of hangtime through the Top Gun Stall lingers longer from the last row. If ejector airtime is what you’re chasing, ride the back seat.

Front row trades some of that intensity for the best sightlines — you see the entire layout unfold ahead of you, including the drop into the first airtime hill and the approach into the high five, without another train’s cars blocking your view. It’s also the easiest row from which to spot and photograph the other train during a successful duel.

Because the ride uses one station and one continuous Mobius track, there’s no way to request the ‘green’ or ‘blue’ side specifically — every rider completes the full circuit and experiences both halves regardless of where they sit. Twisted Colossus doesn’t run a dedicated single-rider line, so solo riders typically join the standard queue and get assigned into the next available seat.
