The New Jersey Division of Parks and Forestry manages a public park system which consists of over 50 protected areas designated as state parks, state forests, recreation areas, and other properties within the state of New Jersey in the United States. The agency also owns and manages 38 historical sites and buildings throughout the state (some located within the boundaries of state parkland) and also owns five public marinas and four public golf courses. These properties are administered by the Division's State Park Service, founded in 1923. New Jersey's state park system includes properties as small as the 32-acre (0.13 km2) Barnegat Lighthouse State Park and as large as the 115,000-acre (470 km2) Wharton State Forest. The state park system comprises 430,928 acres (1,743.90 km2)—roughly 7.7% of New Jersey's land area—and serves over 17.8 million annual visitors.
