About Great Bay National Wildlife Refuge

Great Bay National Wildlife Refuge protects vital tidal salt marshes and estuarine habitats along Great Bay in New Hampshire, offering excellent opportunities for wildlife observation and nature exploration.

Wilderness Landscape & Natural Heritage

Great Bay National Wildlife Refuge spans approximately 1,100 acres of critical estuarine habitat located along the Great Bay in southeastern New Hampshire. The refuge encompasses tidal salt marshes, mudflats, coastal forested uplands, and freshwater wetlands that support a diverse range of plant and animal species. It is part of the larger Great Bay estuary system, one of the largest uninterrupted estuaries in New England, known for its ecological importance as a nursery and feeding ground for numerous fish and bird species. Established in 1992, the refuge serves both conservation and recreational purposes. Visitors can engage in wildlife viewing, nature photography, and environmental education along several accessible trails and observation platforms. Key resident and migratory species include osprey, herons, egrets, bald eagles, and numerous migratory waterfowl. The refuge also plays a central role in protecting endangered species and maintaining water quality in the bay. There are several trails that wind through salt marsh edges and forest habitats, connecting to scenic overlooks where visitors can see seabirds and tidal activity. The proximity of Great Bay Refuge to the town of Portsmouth and other coastal communities makes it a favored spot for residents and tourists alike seeking peaceful natural environments and outdoor learning opportunities. Seasonal bird migrations, salt marsh ecology demonstrations, and guided nature programs enhance visitor experiences throughout the year. Facilities include parking areas and informational kiosks, but minimal developed infrastructure preserves its quiet, natural character.
