Accord Brook flows through McKenna Marsh, 100 acres, which features a 1-mile trail through woodland and along the edge of a freshwater marsh. 

According to the Hingham Conservation Land Trust, the freshwater marsh here was once used as a waterfowl preserve. McKenna Marsh is immediately adjacent to some of the town wells for Hingham and Norwell.

Beavers have been spotted on this property. Look for evidence of them in the area around Accord Brook. You may see a dam or some chewed-up trees. Some of the trees present here include pine, oak, maple, cedar, and beech.

Accord Brook flows through this property and eventually into Wompatuck State Park, through Triphammer Pond, and to the Weir River. Formed at the confluence of Crooked Meadow River and Fulling Mill Brook, the Weir River flows for a mile or so north through Hingham. Farther downstream, it turns northeast and flows for another 1.4 miles, through Weir River Farm and eventually into Foundry Pond. The Weir River Estuary, designated by the Commonwealth of Massachusetts as an Area of Critical Concern, begins just below the manmade dam at the pond. The mile-wide estuary forms the border between Hingham and Hull and empties into Hingham Bay.

A property sign on Scotland Street marks the trailhead. The 1-mile trail leads through open woodland to a bridge over Accord Brook, and then along the edge of a large freshwater marsh. From there, it continues through a more dense pine forest, ending at the Norwell Water Department land on Grove Street. Within the pine grove, a spur trail leads to the Wanders Drive neighborhood.
