Big Thunder Mountain Railroad at Magic Kingdom will reopen on May 3, 2026, after closing for refurbishment in January 2025. The ride is lowering its height requirement from 40 inches to 38 inches. Disney promises new effects including Rainbow Caverns to enhance the experience.
Big Thunder Mountain Railroad shut down on January 6, 2025, for maintenance to ensure long-term operation. The refurbishment includes general renovations and the addition of Rainbow Caverns, featuring shimmering iridescent illuminations that will bring the mountain to life. Disney officials described the work as keeping the attraction in tip-top shape for guests riding the rails into the future, with more new magic to discover upon reopening. The height change opens the ride to younger visitors previously excluded by the 40-inch limit. Frontierland is seeing broader changes alongside the ride's return. Piston Peak, a new Cars-themed area, will replace the closed Rivers of America and Tom Sawyer Island, though no opening date has been set. Separately, a Disney Villains land is planned behind Big Thunder Mountain as its own distinct area.
