Big Thunder Mountain Railroad Height Limit Sign

Walt Disney World has setup height limit or height restrictions signs for all of the minimum height requirement attractions in the Magic Kingdom. Big Thunder Mountain Railroad (BTMRR) has one of these signs. The sign is located at the front entrance for the ride, right underneath the Big Thunder Mountain Railroad sign. The sign has a “measuring stick” attached to it so you can check if your guests meet the height requirement.

To ensure you have the most accurate height requirement, double check the Walt Disney World website or the mobile apps. Walt Disney World usually does not change the height requirements for rides once they are set. We will update this page if Walt Disney World makes changes to the Big Thunder Mountain Railroad height requirement.
