Since 1975, this has been one of the most popular rides in all of Walt Disney World, and with good reason. Space Mountain is a high-speed roller coaster that uses clever special effects to make you feel like you're seated in a rocket that's racing through space. In reality, you'll be traveling about 28 miles per hour.
This entire ride is experienced in almost total darkness, so riders can't see what's coming. For those who don't normally enjoy roller coasters, this one offers a lot of high-speed sharp turns, but only a few small drops. It also does not travel upside down at any point along the track.
There is a 44" height requirement for this ride.
Space Mountain is one of the busiest attractions in the Magic Kingdom, with consistently long lines all day long. The slowest times at Space Mountain are the first hour the park is open and the last hour before the park closes.
Space Mountain is one of the most valuable FASTPASS attractions, due to its long lines. Make sure to grab a FASTPASS early though, because on busy days Space Mountain runs out of FASTPASS by early afternoon.
