Dyke Road crosses the Green Harbor River in Marshfield. Wharf Creek Conservation Area is adjacent.

Also known as Estes Woods, Wharf Creek Conservation Area features several old stone walls within a relatively open woodland. The views of Wharf Creek and the Green Harbor River are quite nice. Excellent for birders.

There are two trails on this property. One extends for about 0.4 miles from Calypso Lane to Wharf Creek. It begins in a residential area, between #57 and #63 Calypso Lane, and continues as a wide cart path into the woods, across a small stream, and past a power easement. The trail narrows at that point and continues through the woods to the edge of the marsh and Wharf Creek.

The other trail begins at Dyke Road, across the street from the Green Harbor Marina, and leads about 0.33 miles through the woods to the Green Harbor River. There is a small stream crossing at the beginning of the trail, and then it leads into a thicket of trees and underbrush before emerging at the edge of the Green Harbor River.

While the two trails used to connect, they currently do not. The Dyke Road trail is narrow but flat. The Calypso Lane trail is also flat, and somewhat wider. Some sections of the trails are wet and/or overgrown.

Forests of oak, beech, and birch, with plenty of greenbrier and native chokeberry. The thicket along the Dyke Road trail is an ideal place to observe birds. There are also some wetlands on this property. Once you arrive at Wharf Creek and/or the Green Harbor River, watch for the osprey who nest up above (look for the nests on top of the utility poles).

This property is located where Wharf Creek flows into the Green Harbor River. The Green Harbor River finds its source in springs and ponds in Duxbury. It twists and turns through Marshfield via a 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.
