Beach Park is the home to the South Beach section of Illinois Beach State Park, which is otherwise located in Winthrop Harbor. The beach was originally part of Camp Logan, a rifle range developed by the Illinois National Guard in 1892. In World War I and World War II it served as a rifle range for the Great Lakes Naval Training Station. The range remained in operation until 1973, when it was transferred to the Illinois Department of Conservation. In 1950, the Illinois Dunes Preservation Society was established to maintain the natural qualities of the beach. With the help of the Illinois Department of Conservation the area south of Beach Road was established as the state's first natural preserve. The northern beach, between Beach Road and the Wisconsin state border, was obtained between 1971 and 1982.
