Knox County stretches along the western shore of Penobscot Bay, from Thomaston and Rockland to Camden, Rockport and the islands of Vinalhaven and North Haven. Homes at this level often feature deep-water frontage, private docks or moorings, guest cottages and views across the bay to the islands. Camden and Rockport are especially known for historic sea captains’ homes and estates, while St. George, Owls Head and the islands offer more private shorefront settings. Cates Real Estate can help you compare frontage, privacy and proximity to the harbors. You may also want to browse luxury homes in Camden or luxury homes in Rockport.
