The number of coasters varies by specific park, but Six Flags Magic Mountain in California currently holds the world record for the most roller coasters in a single park. As of 2026, Magic Mountain features 20 roller coasters, ranging from the legendary X2 (the world's first 4D coaster) and Tatsu (a flying coaster) to the record-breaking Wonder Woman Flight of Courage. Other major parks in the chain, such as Six Flags Great Adventure in New Jersey and Six Flags Over Texas, typically house between 13 and 15 coasters. In 2026, the brand has focused on integrating newer "Single-Rail" technology and hybrid wooden-to-steel conversions to keep their counts high while maintaining ride smoothness. Across the entire North American chain, Six Flags operates over 150 coasters. If you are a "credit hunter" looking to ride as many as possible in one trip, Magic Mountain remains the undisputed "Thrill Capital of the World," offering a higher density of high-speed inversions and drops than any other theme park on the planet.
