Enjoy unique terrain, habitat and special features while exploring three different trails, passing through mature forests and connecting with the larger trail system of Bradley Palmer State Park.
At the time of English settlement, Indigenous people known as the Pawtucket or Agawam were fishing here before there was a dam. They fished for alewives (river herring), shad, and other anadromous species on their spring runs, as well as for catadromous Atlantic eels.
Eels were a culinary delicacy and had other important uses. Crushed eel skeletons were added to baby food as a kind of protein powder, and the cured skins were used as soft strong cradleboard ties, moccasin laces, and tumplines.
Look for Greenbelt’s fish ladder that allows passage of migrating fish around the Willowdale Dam, which once powered a former woolen mill.
The Southern Trail passes through mature hardwood forests and the Riverside Trail follows the banks of the river upstream and also leads you off property into the Bradley Palmer State Forest.
The Willowdale Mill Reservation protects 1,500 feet along the Ipswich River.
The woods are dominated by cedar, hemlock, hardwoods and white pine allowing for fine broad paths carpeted in layers of pine needles for walking or horseback riding.
The river is a great place to see red-breasted merganser and snapping turtles, or try your luck fishing for trout. Deer and other woodland mammals are common, as are owls in the dark woodlands.
