Walt Disney World just gave this iconic ride a makeover—and the newest look is rainbow-themed

One such ride is Big Thunder Mountain Railroad, which first opened in the Magic Kingdom’s Frontierland area in 1980. The mine train roller coaster went largely unchanged for more than 40 years, before the park announced that it would close in January 2025 for a year-long renovation. [Photo: Disney] Since then, fans have clamored for an official reopening announcement, and as of April 8, they finally have one: The reimagined (or re-imagineered) version of Big Thunder Mountain Railroad will open to the public on May 3. Disney announced the reopening date with a cheeky video on social media, where a spokesperson was beset by comments from fans demanding news about the ride. “If Big Thunder Mountain’s what you want, Big Thunder Mountain’s what you’re gonna get,” they said, before revealing that a revamped version of the ride is mere weeks away.

That includes the lore behind it: that greedy gold baron Barnabas T. Bullion discovered gold in Big Thunder Mountain and started a mining company, only for the mountain to fight back and leave his mines deserted. But the reimagined ride will feature at least one new locale, the Rainbow Caverns, which will feature “spectacular natural caverns full of phosphorescent pools,” per Disney’s press release. “The Rainbow Caverns certainly are beautiful . . . but they ain’t as friendly as they first appear,” it continues. “In fact, that menacing rumble from deep within the mountain may be a sign that we ain’t welcome.” The ride will also be more accessible thanks to a lowered height requirement of 38 inches, reduced from the previous requirement of 40 inches.

In 2024, log flume Splash Mountain was replaced with Tiana’s Bayou Adventure, themed around the 2009 animated film The Princess and the Frog. The original attraction had drawn controversy for taking inspiration from Disney’s 1946 movie Song of the South, which includes racially insensitive portrayals of Black Southerners after the Civil War. Another rebranded ride coming to Disney later this year is Rock ‘n’ Roller Coaster, now starring The Muppets instead of Aerosmith. The rock band had featured in the ride’s pre-show since its opening in 1999, but will be replaced when the coaster reopens this summer. Why simply rebrand or revamp an existing ride rather than replace it entirely or create new attractions elsewhere? Bob Weis, then-president of Walt Disney Imagineering, explained the company’s rationale in 2020 in reference to scrapping Splash Mountain for Tiana’s Bayou Adventure. “We have a longstanding history of enhancing attractions with ‘new magic,’” Weis said. “We completely understand that these decisions aren’t always popular, but I think our biggest fans know that we care as much as they do.”
