One of the best Magic Kingdom rides! Big Thunder Mountain is one of the most underrated WDW rides! The wait can get kind of long on busy days but if you time. Pros: amazing theming thrilling ok views Nice for the whole family (don't recommend for ages 6 and. The Big Thunder experience was an odd mix of merry-go-round and jump castle. Excellent Reviews. Any number of bad birthday parties with legions of screaming. amazing, very thrilling ride, one of my personal favorites. "The Wildest Ride in the Wilderness!" This ride looks alot more fun than just looking at it from the path/queue line. Tho the chain life is very loud.
