The Bellamy River Wildlife Sanctuary is located on the western bank of the Bellamy River, approximately eight miles upriver from the seacoast. The Bellamy River is part of the Piscataqua River watershed, which also includes the Great Bay and the Oyster River. The River is estuarine, which means its freshwater flow combines with the saltwater of incoming tides. With a tidal change of approximately five to six feet, the shoreline contains expanses of mud flat during low tides. Quality estuarine systems such as this are vital to the health and abundance of coastal and marine life, as well as for migrating, wintering, and breeding birds.

The Sanctuary consists of 26 acres of forest, several small tidal creeks, and small coves of a brackish salt marsh. Less than 20 feet above sea level in elevation, the Sanctuary has a relatively flat terrain, with silty, moist soils that support mixed and deciduous forest dominated by oak (red, black, and white), red maple, white pine, shagbark hickory, and black birch.
