(California)
Benicia State Recreation Area is a state park unit of California, United States, protecting tidal wetland. It is located in the Solano County city of Benicia, 2 miles (3.2 km) west of downtown Benicia and borders Vallejo's Glen Cove neighborhood. The park covers 447 acres (181 ha) of marsh, grassy hillsides and rocky beaches along the narrowest portion of the Carquinez Strait. Southampton Creek and the tidal marsh front Southampton Bay, where the combined waters of the Sacramento and San Joaquin Rivers approach San Pablo Bay, the northern portion of San Francisco Bay.
