Mendocino Woodlands State Park is a coastal Northern California group camping park established in the 1930s through New Deal programs as a Recreational Demonstration Area for youth summer camps. Built by the Civilian Conservation Corps and Works Progress Administration, it was one of forty-six such campgrounds and the only one to remain in continuous public camping use. The park now spans about 700 acres in a second-growth redwood forest along the Little North Fork of the Big River, supporting diverse wildlife. Its original 5,425-acre tract was reduced when it entered the California state park system in 1976, and its historic significance was recognized in 1997 with National Historic Landmark designation.
