About Great Marsh Preserve

Great Marsh Preserve is a vast expanse of coastal marshland in Delaware, offering visitors a unique opportunity to explore tidal habitats and witness diverse birdlife.

Wilderness Landscape & Natural Heritage

The Great Marsh Preserve is one of Delaware's largest expanses of preserved coastal marshland, covering thousands of acres of tidal and non-tidal wetlands. This area is characterized by its expansive marsh grasses and winding water channels, providing critical habitat for various bird species, especially during migration periods. Historically, the marsh has been used for both its natural resources and its strategic location near the Delaware Bay. Birdwatching is a particularly popular activity at the preserve, with opportunities to spot herons, egrets, and other marsh birds. The preserve also supports a range of wildlife, including fish and small mammals, due to its healthy ecosystem. Access to the preserve is typically granted to foot traffic via a number of trails that provide vantage points for photography and nature appreciation. The area appeals to nature enthusiasts and those seeking a quiet retreat into a unique and important ecological landscape.
