Whether the Matterhorn Bobsleds at Disneyland is "scary" depends on what a rider finds intimidating, as it blends physical thrills with atmospheric "spookiness." Physically, it is a high-speed, jerky roller coaster that was the first tubular steel coaster in the world, meaning it lacks the smoothness of modern rides and features sharp, unexpected turns and dips. The cars "rattle" quite a bit, which can be unsettling for those sensitive to rougher rides. The most frightening element for many, however, is the "Abominable Snowman" (Harold), an animatronic creature that appears several times throughout the mountain with a loud, piercing roar. The ride takes place largely in the dark or in dim tunnels, which adds to the suspense. There are also two small "splashdowns" at the end, though you rarely get more than a light misting. While it doesn't have inversions or massive drops, the combination of the dark, the growling Yeti, and the bumpy nature of the sleds makes it a "thrill" ride that might be too intense for very young children or those who dislike sudden noises and darkness.
