Jackson is the state capital. The state’s largest metropolitan areas are Jackson, Biloxi, Gulfport, and Pascagoula. Gulfport and Pascagoula can accommodate oceangoing ships, and low-draft oceangoing vessels can travel up the Mississippi River to Natchez, Vicksburg, and Greenville. Barge traffic moves on the Mississippi, Pearl, and Yazoo rivers. The Gulf Intracoastal Waterway passes through the Mississippi Sound along the Gulf Coast.
