Space Mountain is a roller coaster in Tomorrowland at Walt Disney World's Magic Kingdom. While it's not the best, it is also recommended. The minimum height to ride is 44 inches.
Guests board sleek rocket trains with single-file seating and blast off on an adventure through space in this indoor roller coaster. The ride was refurbished in 2010 and now offers some additional on-ride effects, as well as games in the queue to help you pass the time while you await your "flight." Space Mountain is not a fast coaster — the top speed is only around 28 mph — but it is twisty, with over 3 Gs in lateral forces on some whippy turns.
