The 2,339-acre Graveline Bay preserves is one of the few relatively undisturbed estuarine bays in the small tidal creeks in Mississippi. The area supports salt marsh, brackish marsh and oyster beds. The bay, marsh, adjoining upland forest and undeveloped beach front near the mouth of Graveline Bayou are an important landing area for neotropical migration birds. A near-by boat launch at the end of Octavia Street offers easy access for kayaking and canoeing.
