The Liverpool area has easy access to some of the South Shore's best beaches, and this one has more than a kilometer of fine, pale-colored sand. Backing the beach is a dune system that shelters nesting sites for piping plovers—a clue to the location's uncrowded tranquility—and beyond this are salt marshes. The shallow water makes Summerville ideal for families, and near the beach is a picnic area with tables that have sunshades. Amenities: parking (free); toilets. Best for: solitude; sunsets; swimming; walking.
