Big Thunder Mountain Railroad
38"97cmA runaway mine train through a red-rock desert, and the best first roller coaster for most kids at 38 inches.
Big Thunder is a family coaster dressed up as a mining disaster. There are no inversions, no steep drops and a top speed around thirty miles per hour, but the track is laid out to whip you sideways through banked curves inside a hand-sculpted red rock formation stretching almost two hundred feet across Frontierland. The thrill is entirely lateral.
Tips for Big Thunder Mountain Railroad
- Back row for intensity, front row for scenery. Ask for the back and expect to wait one extra train cycle — it is worth it.
- Ride it after dark. The mountain is lit from within, you cannot see the next curve coming, and the whole thing feels roughly one notch faster than it does at noon.
- The height requirement is 38 inches as of May 2026, down from 40. If your child was measured on a trip before that, measure again — a lot of families do not know it changed.
- This is the correct rope-drop target if you have small kids and are skipping TRON. It is closer to the entrance than Seven Dwarfs Mine Train and the line builds more slowly in the first hour.
- Loose items go in the small floor bin at your feet or in a pocket that zips. There are no lockers, the lateral forces are real, and phones do come out of laps here more than on any other Magic Kingdom coaster.
- The single most reliable low-wait window is during the afternoon parade, when the parade route cuts Frontierland in half and casual traffic stops flowing toward the mountain.
