The conservation area is comprised of the area extending from the beaver pond eastward to Route 3 , as well as the entire area south of the dirt access road that bisects Vietnam Veterans’ Memorial Park, exclusive of the new soccer field and parking lot.

This lower portion of the conservation area is characterized by a large area of white pine/oak forest that may provide suitable habitat for interior-nesting birds. The topography is varied, with high ridges and a steep slope down to the riverbank. The conservation area has considerable aesthetic appeal, with attractive river views and exposed bedrock formations. The area features approximately 2000 feet of frontage along the Concord River. This stretch of the river is part of the federally designated Wild and Scenic Rivers corridor. Also featuring prominently on the property are Winning Pond and a large beaver pond. Wetlands areas are located east of the beaver pond along Route 3 and just north of the larger portion of Ralph Hill Woodlot. Two vernal pools are also located on the property.


From Route 3 north or south, take Exit # 28 – Treble Cove Road. Go southwest ½ mile. The park entrance will be on your left.
