Whether TRON Lightcycle / Run is "scarier" than Space Mountain depends on what kind of thrill you prefer. TRON is significantly faster, launching you at 59 mph (more than twice the speed of Space Mountain), and features a high-speed outdoor "canopy" section that can be intense for those with a fear of heights. Its motorcycle-style seating, where you lean forward and are secured by a back restraint, also feels more "exposed" and modern. However, Space Mountain is often considered more "frightening" by some because it takes place in near-total darkness, making every drop and turn completely unpredictable. Space Mountain is also much "jerkier" and rougher due to its older track design, which creates a sense of "wildness" that the buttery-smooth TRON lacks. In 2026, most guests agree that TRON is the more "thrilling" and visually stunning experience, but Space Mountain remains the "spookier" ride because of its sensory deprivation and classic, rickety "mine train" feel in the dark.
