Space Mountain opened at Disneyland in Anaheim, California on May 27, 1977, becoming the second roller coaster ever built at the park and the second version of Disney’s space-themed coaster concept, following the original at Walt Disney World’s Magic Kingdom in 1975. Designed by Walt Disney Imagineering’s Bill Watkins and built by WED Enterprises, the ride realized an idea Walt Disney himself first conceived after the success of the Matterhorn Bobsleds. The opening ceremony was notable enough to draw six of the original Mercury Seven astronauts.
Set entirely inside a distinctive white cone-shaped building in Tomorrowland, Space Mountain uses near-total darkness, synchronized lighting, and sound effects to make a modest 32 mph top speed feel far faster. The ride underwent a major renovation from 2003 to 2005 that replaced its entire track system after the added weight of an onboard audio system compromised the original structure. Nearly five decades after its debut, it remains one of Disneyland’s most iconic attractions and periodically transforms into a Star Wars-themed “Hyperspace Mountain” overlay.

The Ride Experience
Riders board 12-passenger trains that climb a lift hill before plunging into total darkness, where the twisting layout and sudden drops feel more intense than the coaster’s actual numbers suggest. Strobe lights, star fields, and a full audio track are synced to the train’s movement, creating the illusion of hurtling through deep space. The ride lasts about two minutes and 45 seconds and runs 11 trains at once, moving up to 1,800 riders per hour.
A Half-Century of Space Travel
Walt Disney envisioned a space-themed coaster for Disneyland as early as 1959, but the concept didn’t reach Anaheim until 1977, two years after debuting at Walt Disney World. By the early 2000s, the added weight of onboard speakers had worn down the original support structure, prompting a full track replacement completed in 2005. Since then, Disney has periodically reskinned the ride as “Hyperspace Mountain,” layering Star Wars music and visuals over the same classic layout.
