Untamed is a hybrid roller coaster at Walibi Holland in Biddinghuizen, Netherlands, built by Rocky Mountain Construction (RMC). Opening on July 1, 2019, it converted the former Robin Hood wooden coaster into one of Europe’s most acclaimed rides by replacing the aging wooden track with RMC’s signature steel I-Box rails while retaining much of the original wooden support structure.
Standing 120 feet tall and reaching 57 mph across 3,560 feet of twisting track, Untamed set the world record for the most inversions on a hybrid roller coaster — five in total — woven between 14 moments of powerful airtime. In its debut year it earned fifth place in Amusement Today’s Golden Ticket Awards for Best New Roller Coaster, and it has continued to place among the world’s top steel coasters in later editions of the same poll.

The Ride Experience
Untamed launches riders up a chain-lift hill 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 rotates 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. 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 a single 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.
It’s worth noting 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, which is why enthusiast rankings consistently praise its pacing over its raw numbers.
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.
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 one of the park’s eight 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 (available in Silver, Gold, and Single Shot tiers) lets you reserve a return time for Untamed and skip the standard queue when it’s your turn.
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, with online advance pricing typically running cheaper than box-office prices, alongside season passes and discounted afternoon or off-peak tickets. Parking is available on-site for a separate fee, with details on directions and drop-off points listed under the park’s practical information pages.
Because hours, ticket tiers, and prices change throughout the year, always confirm the current schedule and pricing on Walibi Holland’s official Plan Your Visit page before you go, and check the official Untamed attraction page for same-day closures or maintenance notices.
Awards & Ongoing Recognition
Untamed placed fifth in Amusement Today’s 2019 Golden Ticket Awards for Best New Roller Coaster, cementing its reputation in its debut season. It has remained a fixture in the publication’s annual Top Steel Coaster rankings in the years since, a sign that the ride quality has held up well beyond its opening buzz — something not every hybrid conversion manages.
