Rockland-Abington Reservoir, also known as the Hingham Street Reservoir, is a picturesque public water supply surrounded by a 1.5-mile trail. The reservoir, which supplies water to the towns of Abington and Rockland, is located on Hingham Street in Rockland, but the trail access is in Hanover. Access from the John Hannigan Water Treatment Plant in Rockland is not permitted.

Access the trail from Deerfield Lane in Hanover. If you’re driving in from Whiting Street, look for the trailhead on the right, just before Deerfield Lane makes a sharp curve to the left. Park along the side of the road and look for the trailhead. It passes quickly through a woodland and out to the reservoir, where it extends around the perimeter. The trail is mostly level and clear. It is bordered by young pine, birch, and maple trees, and an abundance of sweet pepper bush. Along the trail, you’ll find occasional boulders and outcroppings of rock, which generally offer the best views of the water.
