South Thomaston
The town lies on the Weskeag River, which broadens into several large coves before emptying into the Muscle Ridge Channel. In addition to the main village, Pleasant Beach, Waterman Beach, and Spruce Head villages hug the shore on Penobscot Bay. Spruce Head Island, connected to the mainland by a bridge, juts into Muscle Ridge Channel, a favorite passage for boaters seeking the protection of the outlying islands.
