Untamed at Walibi Holland is the ride enthusiasts point to whenever the conversation turns to hybrid coasters that do more than deliver airtime — its five inversions are still the benchmark for the entire RMC hybrid category more than five years after it opened. If you’re trying to nail down exactly how tall, how fast, and how intense this ride really is before you get in line, every verified stat, record, and practical detail is below.
This guide covers the full technical breakdown, how Untamed stacks up against sibling RMC hybrids like Steel Vengeance and Twisted Colossus, who can and can’t ride, which row to pick, and how to plan your visit around wait times, Fast Lane tiers, and Walibi Holland’s ticketing system.
Quick Answer
Untamed is a 120-foot-tall Rocky Mountain Construction (RMC) hybrid coaster at Walibi Holland in Biddinghuizen, Netherlands. It reaches 57 mph (92 km/h), holds the world record for most inversions on a hybrid coaster (five), and requires riders to be at least 120 cm (about 3’11”) tall. It opened July 1, 2019, on the site of the former Robin Hood wooden coaster and is widely credited as Europe’s first hybrid roller coaster.

The Ride Experience
Untamed’s chain lift hauls trains up to the top of the structure before pitching them into a 116-foot drop at an 80-degree angle. The layout then delivers a relentless blend of hangtime and ejector airtime, highlighted by a 270-degree Double Inverting Corner Stall right after the first drop — a signature RMC element that flips trains completely upside down twice in quick succession while sweeping through a wide arc.
Additional inversions include a Step-Up Under Flip, an Over-Banked Inversion, and a Barrel Roll, giving riders five inversions in all — the most ever built into a hybrid coaster. Trains are styled to look like insects and use a lap-bar-and-seat-belt restraint system. With G-forces peaking at 3.75g and 14 distinct airtime moments packed into roughly 1 minute 46 seconds, Untamed rewards riders with an extraordinary variety of sensations rather than one repeated element.
From Robin Hood to Untamed: A Coaster Reborn
The plot of land was previously occupied by Robin Hood, a traditional wooden coaster designed by Stand Company and built by Vekoma that ran at Walibi Holland from April 2000 until its closure on October 28, 2018. It had no inversions, a roughly 2:25 ride time, and a capacity of about 815 riders per hour.
Rather than demolishing the structure outright, RMC retained much of the existing wooden skeleton and rebuilt the ride from the rails up using their proprietary I-Box steel track technology, a process that defines the company’s celebrated hybrid coaster conversions. Construction began in late October 2018, track topped out on May 16, 2019, and test runs started in early June before the July 1 opening. Nods to the old ride remain in the queue, where original Robin Hood track sections and a train car are displayed.
How Untamed Compares to Other RMC Hybrid Coasters
RMC’s hybrid coasters generally fall into two camps: airtime-focused rebuilds with few or no inversions (Steel Vengeance at Cedar Point, Twisted Colossus at Six Flags Magic Mountain, Wildfire at Kolmården) and inversion-heavy layouts like Untamed that push the I-Box track’s tight-radius capabilities to their limit. Untamed’s five inversions remain the benchmark for the hybrid category, a title it has held since 2019, and it’s generally recognized as the first hybrid coaster to open in Europe.
Untamed is not the tallest or fastest RMC ride — new-build I-Box coasters such as Zadra at Energylandia and Iron Gwazi at Busch Gardens Tampa Bay top it on height and speed. What sets Untamed apart is density of elements: within a compact 3,560-foot layout it crams in more distinct inversions than any other hybrid coaster on the planet. It has also stayed a fixture in Amusement Today’s Golden Ticket Awards years after opening, most recently landing among the top 50 steel coasters worldwide in both the 2024 and 2025 polls — a long tail of recognition most 2019-era coasters don’t manage.
Height Requirement, Restraints & Who Can Ride
Riders must be at least 120 cm (about 3 feet 11 inches) tall to board Untamed. Trains use a lap-bar-and-seat-belt restraint system, and the ride is not recommended for pregnant riders due to the inversions and G-forces.
A baby switch (child swap) option is available for parents traveling with younger children who don’t meet the height requirement. Guests with disabilities can check the park’s published accessibility documentation to confirm eligibility, since restraint fit and the ride’s inversions may affect who can safely ride.
Front Row or Back Row: Which Seat to Choose
Seat choice noticeably changes the ride on Untamed. The front row gives an uninterrupted, cliff-edge view of the track twisting ahead — riders can see the 80-degree first drop and every inversion coming before it hits. It’s the pick for first-timers who want to appreciate the layout.
The back row is the one enthusiasts chase for intensity: the whip effect through the airtime hills and the Double Inverting Corner Stall is noticeably stronger, since the rear cars travel faster through dips and lag through crests. If you’re riding more than once, doing one lap in each row is the best way to experience everything Untamed offers.
Wait Times, Single Rider Line & Fast Lane
Untamed is one of the busiest attractions at Walibi Holland, and posted waits can climb well past an hour on peak summer afternoons; arriving at park opening is the most reliable way to ride with a short line. Untamed is also among the small group of Walibi Holland attractions with a dedicated single rider line, which fills empty seats left in the regular queue — expect a noticeably shorter wait, though your group won’t necessarily sit together.
For guests who don’t want to use the single rider line, Walibi Holland’s Fast Lane system covers Untamed alongside other headline rides such as YOY, Lost Gravity, and Goliath. Tiers range from Single Shot and 4 Shot passes (skip the queue once or four times on rides of your choice) up to Bronze, Silver, and Gold reservations that reduce or virtually eliminate wait time on Fast Lane attractions. Exact pricing and availability change by season, so check Walibi Holland’s official Fast Lane page before you go.
Planning Your Visit
Walibi Holland’s operating hours shift by season, generally running from mid-morning into the evening on operating days, with extended hours during peak summer weeks and shorter schedules in the off-season. Standard day tickets are sold both at the gate and online, and the park uses dynamic pricing, so advance online tickets are typically cheaper than box-office pricing, especially on busier calendar days.
For current opening times, ticket prices, and any calendar exceptions (some blackout or event dates restrict undated tickets), check the official Walibi Holland website and its tickets page directly, since both change throughout the year.
Untamed Walibi Holland roller coaster FAQs
How tall do you have to be to ride Untamed?
Riders must be at least 120 cm (about 3 feet 11 inches) tall. There is no published maximum height restriction, but the lap-bar-and-seat-belt restraint must fit properly.
What world record does Untamed hold?
Untamed holds the record for most inversions on a hybrid roller coaster, with five: a 270-degree Double Inverting Corner Stall, a Step-Up Under Flip, an Over-Banked Inversion, and a Barrel Roll.
Is Untamed the tallest or fastest coaster at Walibi Holland?
No. Goliath, the park’s Intamin mega coaster, is both taller (about 154 ft) and faster (66 mph) than Untamed, though it has no inversions. Untamed’s distinction is inversion density, not raw height or speed.
Does Untamed have a single rider line?
Yes. Untamed is one of the Walibi Holland attractions with a single rider line, which typically moves faster than the standard queue by filling empty train seats, though your group may be split up.
What ride was at this location before Untamed?
Robin Hood, a wooden coaster built by Vekoma, operated on the site from 2000 to 2018. RMC kept much of its wooden support structure and rebuilt it with steel I-Box track to create Untamed.
Front row or back row — which is better on Untamed?
Front row gives the best unobstructed view of the track and drops; back row delivers stronger whip and airtime through the hills and inversions. Riding both is the best way to experience the full layout.
