Space Mountain is an excellent roller coaster in Tomorrowland and one of the best attractions at Disneyland. The minimum height to ride is 40 inches.
Originally opened in 1977, the Anaheim version of Disney's indoor "wild mouse" coaster ride through space now features an on-ride musical soundtrack, as well as a special Halloween version, "Ghost Galaxy" that runs in October.
Disneyland's Space Mountain also includes a dedicated loading bay for disabled guests, so they can load at their pace. The ride vehicle is on a platform that will eventually be slid into place and take off like other ride vehicles.
