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. See how Colossus became Twisted Colossus, and where both fit among every coaster Six Flags Magic Mountain has ever run, on our Six Flags Magic Mountain roller coaster history timeline.
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, how to cut down your wait, 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 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. Six Flags lists the ride at a thrill level of 4 out of 5 — intense, but driven by steep drops and sustained airtime rather than disorienting snap turns.
Height Requirement and How Rough It Rides
Riders must be at least 48 inches tall to ride Twisted Colossus, measured at the entrance, with a standard lap-bar restraint rather than an over-the-shoulder harness. That lower bar means the ride relies on rider positioning rather than heavy padding, which is part of why airtime hills feel so sharp.
Twisted Colossus rides rough by reputation mainly in the sense of being forceful, not jarring — RMC’s I-Box steel track is engineered to be dramatically smoother than a traditional wooden coaster while still delivering the pacing of one. Expect strong, repeated bouts of ejector airtime on the camelback-style hills, firm lateral forces through the banked turns, and a floaty, extended hang during the inverted Top Gun Stall. It’s physically demanding in the way a great wood-frame coaster is, but riders and reviewers consistently describe the trains and track as buttery smooth compared to the pre-2014 wooden Colossus.
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.
Best Seat: Front Row vs. Back Row
There’s no single correct answer because the front and back rows reward you for different reasons. The front row gives the clearest sightline down the drops and the best view of the oncoming train during the high five, since you’re not looking past rows of other riders to see it coming.
The back row delivers the strongest airtime, because the rear of the train whips through each camelback hill and the Top Gun Stall with more hang time than the seats near the lift hill. If you can only ride once, most enthusiasts lean toward the back half of the train for the raw airtime; if you want the best photo-and-view experience of the duel itself, pick the front. Riding it both ways — once up front, once in back — is the only way to get the full picture, and the single-rider line (when open) is the fastest way to cycle through both without a long wait.
Skipping the Line: Wait Times and Flash Pass
Twisted Colossus is one of the park’s most popular credits, so it routinely builds long midday waits on busy weekends and holidays; arriving at park opening or riding during the last hour before close typically means the shortest lines. Six Flags Magic Mountain sells a pay-per-ride Flash Pass that lets you reserve a return time for specific attractions, including Twisted Colossus, for an extra fee that varies by ride and by day.
Because pricing, single-rider availability, and seasonal operating days change throughout the year, check the official Six Flags Magic Mountain Twisted Colossus page before your visit for the current height-requirement signage, operating schedule, and Flash Pass pricing.
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 moment: as the two trains cross paths on parallel sections of track, they pass close enough that riders on each train can reach out toward one another, hands almost touching at speed. It’s the signature image that distinguishes Twisted Colossus from every other hybrid coaster, since it only exists because the layout is one continuous Mobius loop rather than two separate tracks.
The Top Gun Stall is the ride’s inverted centerpiece — one of Twisted Colossus’s two inversions, it carries the train upside down and holds it there briefly before gravity pulls it back through, delivering a weightless, floating sensation rather than a quick snap. Combined with the earlier Zero-G Roll, it gives Twisted Colossus two distinct inversions that feel more like suspended holds than typical loops, which is part of why enthusiasts rate the ride’s pacing above its raw stats.
