Big Thunder Mountain Railroad will reopen at Magic Kingdom on May 3, 2026, ending a closure that began in January 2025 and has kept one of the Walt Disney World® Resort’s signature attractions offline for about 16 months. In recent days, testing has been visible at the ride, including steam effects from pipes near the queue building and Imagineers checking the geyser features on the shuttered mountain.
The refurbishment was not a routine tune-up. Disney said the project was its most intensive overhaul ever at the attraction, and it included a complete replacement of the steel roller coaster track plus freshly painted trains installed across the entire ride system. The company also said guests will find new magic alongside the ride’s classic storytelling and trademark energy when it opens again.
Big Thunder has been running since 1980, and its absence has left a gap in Frontierland that was impossible to ignore. The landmark attraction sits at the center of a part of the park that felt incomplete without it, even as work continued around it. Construction walls still surround much of the entrance area, and they are expected to stay up after reopening as the broader Frontierland transformation continues.

Disney has said the ride will also have a new height requirement, and the most significant new storytelling element is the Rainbow. That gives the reopening more than the feel of a repair job; it is being treated as a reset of one of the park’s best-known rides. The question now is not whether Big Thunder returns on schedule — Disney has already answered that — but how much of the mountain will feel familiar once guests board on May 3.
