We only saw six of the ten lighthouses on the Cape, simply because they are so spread out. However, Provincetown has three lighthouses, and the one in nearby Truro was ordered to be built by George Washington! There are also lighthouses in Falmouth, Barnstable, Hyannis, Yarmouth, Chatham, Orleans, and Eastham.
Martha's Vineyard has four lighthouses in Gay Head, West Chop, East Chop, and Edgartown. All are accessible. Nantucket has three lighthouses in Great Point, Sankaty, and Brant Point. All are accesible except for Great Point, which is at the end of a three mile long barrier beach.
