The east side of the Damariscotta River once contained an enormous shell heap named Whaleback because of its shape. Much of this midden was removed in the late 1880s to supply a factory built here to process the oyster shells into chicken feed. As a result, only a small portion of Whaleback remains today. Managed in cooperation with the Coastal Rivers Conservation Trust, the area around the midden is now a State Historic Site that includes a small hiking trail and beautiful views of the river. A series of interpretive panels helps inform visitors about the history of the area.

This 159-acre wetland preserve was one of the first areas settled on Westport Island. Hike along the 1.8 mile Jeremy’s Ramble Trail, exploring several short side trails. These blazed trails begin at the parking area off West Shore Road and proceed through hardwood forest, along a picturesque stone wall and by the lush green marsh grass of the wetland along the creek.
