Knott’s Berry Farm is preparing to reopen one of California’s most recognisable roller coasters after a four-year redevelopment that blends modern ride technology with an expanded themed experience. The attraction, now named MonteZOOMa: The Forbidden Fortress, will make its media debut on 20 July, with a public opening expected shortly afterwards.
Originally opened in 1978 as Montezuma’s Revenge, the Schwarzkopf-designed coaster became the world’s first flywheel-launched roller coaster. It has remained a favourite among enthusiasts for nearly five decades and is recognised as the last operating example of its type in the United States. The attraction closed in 2022 for a major refurbishment after several delays and design revisions.
Rather than preserving the original launch system, the park has installed a synchronous motor launch that replaces the ageing flywheel mechanism. The new system also introduces a randomised launch sequence, meaning riders will not know exactly when the train will accelerate, adding an extra layer of anticipation before each dispatch.
The redevelopment extends beyond the ride hardware. Guests will now pass through a newly themed queue based on a hidden fortress linked to the legend of the Aztec emperor Montezuma. Scenic elements include traps, relics and the remains of previous treasure hunters, while redesigned ride vehicles resemble mythical stone creatures to support the attraction’s updated storyline.
Dutch engineering company Kumbak has led the transformation of the coaster, while the original attraction was designed by renowned engineer Werner Stengel for German manufacturer Anton Schwarzkopf. The revitalised attraction sits alongside the park’s Jaguar coaster, allowing the expanded Mesoamerican-themed area to create a more cohesive guest experience.
The reopening marks the return of one of North America’s most historically significant launched roller coasters at a time when many classic attractions are either being retired or extensively modernised. For Knott’s Berry Farm, the project demonstrates an alternative approach to heritage attractions – retaining a ride’s identity while upgrading its technology and storytelling for a new generation of visitors.
