Great Swamp covers a total land area of 3349 acres. Acreage is divided among the following cover types: wetlands (2262 acres), forest cover (897 acres), agricultural land (eighty-eight acres), and other lands (102 acres; brush, utilities, etc.). The area contains extensive forested freshwater wetlands, dominated by red maple swamps with some cedar swamp.

The Great Swamp Management Area contains several miles of trails that wind through fields and mixed forests and around an impoundment. The area is a good place to find passerines during spring migration. The trail that circles the impoundment travels through different habitats that attract a variety of birds. It is about a five-mile round-trip hike from the parking area.

The AllTrails website has a description and map of trails at the Great Swamp Management Area.
