Walt Disney World to lower height limit on Thunder Mountain

April 8, 2026, 2:04 PM · Walt Disney World will lower the height restriction on it Big Thunder Mountain Railroad when the roller coaster reopens next month.

Thunder will reopen from a year-plus refurbishment and track rebuild on May 3 at Walt Disney World's Magic Kingdom. When the popular coaster returns, its height requirement will drop from the previous 40 inches to 38 inches, allowing younger and smaller children to ride.

In other Walt Disney World news today, Buzz Lightyear's Space Ranger Spin also reopened after a long refurbishment. The interactive dark ride now features handheld blasters, different-colored targeting beams for each player, and enhanced targets.

I am planning to visit Disney World next month and will post updates then on these and other new and refreshed attractions. In the meantime, if you are in the area and have the opportunity to check them out, please tells us about them in the comments or on the Discussion Forum.

Any guess how or why a height requirement change like that can happen? Was there a change to the restraint system? And any idea if we could see this happen in California?

New trains and new track, from what I understand. Still bench seats and lap bars, though. I'm asking about the other Thunders.

Thank you, sir! Could be a good explainer article about how height requirements are decided by manufacturers and operators.

Excited for the refreshed version of this! I feel like it’s been ages since I’ve ridden it.

Hopefully this bodes well for a smoother ride.
