Knott's Berry Farm is a 57-acre (2,500,000 sq ft; 230,000 m2) amusement park in Buena Park, California, United States, owned and operated by Six Flags. In March 2015, it was ranked as the twelfth-most-visited theme park in North America, while averaging approximately 4 million visitors per year. The park features over 40 rides, including roller coasters, family rides, dark rides, and water rides. Walter and Cordelia Knott first settled in Buena Park in 1920. The park began as a roadside berry stand run by Walter Knott along State Route 39 in California. In 1941, the replica ghost town opened, paving the way for Knott’s Berry Farm to become a theme park. It was officially named Knott’s Berry Farm in 1947. By the 1940s, a restaurant, several shops, and other attractions had been constructed on the property to entertain a growing number of visitors. The site continued its transformation into a modern amusement park over the next two decades, and an admission charge was added in 1968. In 1997, the park was sold to Cedar Fair for $300 million. Cedar Fair later merged with Six Flags in 2024.
