Mass Audubon's North Hill Marsh Wildlife Sanctuary, Mayflower St, Duxbury, MA 02332, USA
Owned By: Town of Duxbury
These woodlands, situated on a hillside overlooking a large pond and wetlands, are located within Duxbury’s 1,000-acre Eastern Greenbelt, and home to the town’s largest trail network.
The Frederick B. Knapp Town Forest is part of Duxbury’s 1,000-acre Eastern Greenbelt. It directly abuts Mass Audubon’s North Hill Marsh Wildlife Sanctuary, as well as the Waiting Hill Preserve and the Round Pond Conservation Area. Within Knapp Forest, you’ll find the Green’s Harbor Path and Kettle Hole Loop trail network, among others. North Hill Country Club is directly adjacent as well.
In earlier times, this land was within the region of the Patuxet, members of the Wampanoag tribe, who inhabited the area around the Jones River now known as Duxbury, Kingston and Plymouth. The forest is named for Frederick B. Knapp (1857-1932), who served as the Headmaster for the Powder Point School for Boys, chief of the Duxbury Volunteer Fire Department, and Forest Warden.
Primary access to the Knapp Town Forest is at North Hill Marsh on Mayflower Street. The Knapp Trail, blazed in yellow, extends a short distance in one direction from the parking area to Mayflower Street, but much greater distance in the other direction, through the woods the O’Brien Bogs, along the Kettle Hole Loop Trail, and beyond to Harrison and Tremont Streets.
The Pond Loop, blazed in blue, extends all the way around North Hill Marsh. A secondary trail, blazed in red, extends from the northern intersection of Green’s Harbor Path and the Kettle Hole Loop, west to the North Hill Marsh trail network.
Additional access to the Knapp Trail is available behind First Parish Church in Duxbury (842 Tremont Street). Follow the stairs, or the trail nearby, to head downhill. Walk past the labyrinth/meditation garden, and continue to the fence that borders Mayflower Cemetery.
