About North Hill Marsh

Common Yellowthroat at North Hill Marsh Wildlife Sanctuary
Common Yellowthroat

North Hill Marsh can best be described as a sanctuary within a refuge. Situated within Duxbury’s Eastern Greenbelt, 1,000 acres of contiguous open space, the sanctuary’s oak and pine woodlands, wetlands, and 90-acre pond provide habitat for wildlife, especially migratory waterfowl.

A clearly marked trail system circles the pond and travels through Duxbury Town Forest.
