The area has over 1,500 acres of riding area that includes more than 80 miles of trails, and offers ATV riders and UTV riders of all skill levels a great place to ride. No “Johnny-come-lately,” Carnegie began as a preferred spot for ATV riding in the 1930’s and 1940’s after years as first a cattle-grazing area, then a popular picnic area. Races were held here in the 1950s, and in the next decade, the privately-owned land was home to the Carnegie Motorcycle Park, until 1979, when the state bought the land to provide a place for off-roading in CA.
