Trail Description

Beach access on the southern end is very limited during higher tides. There is a jetty on the northern end of the beach with views of a long stretch of beach, as well as the channel to Green Harbor itself. Green Harbor Beach is contiguous with Duxbury Beach, so this is a great place for a long walk along the shore!

Habitats and Wildlife

A sandy beach on the Atlantic Ocean, overlooking Cape Cod Bay and contiguous with Duxbury Beach. Located just south of the entrance to Green Harbor itself.

Two rivers flow into the harbor at Green Harbor:

• The Cut River is a manmade channel that connects to Duxbury Bay via a network of marsh creeks. The best place to view the Cut River is from the bridge on Beach Street, a popular spot for swimming (and bridge-jumping) during high tides.

• The Green Harbor River finds its source in springs and ponds in Duxbury. It twists and turns through Marshfield via large cranberry bog complex, the Green Harbor Golf Club, the Daniel Webster Wildlife Sanctuary, property owned by the Marshfield Municipal Airport and Peter Igo Park. Just downstream of the Dyke Road bridge (and dike) it flows into the Atlantic Ocean at Green Harbor. Two excellent places to view the river are from the Dyke Road bridge (along the Harbor Walk) and from the dock at Peter Igo Park, where you can also launch non-motorized watercraft such as canoes, kayaks, paddle boards and even rowing shells!
