Peddocks Island is one of the largest islands in Boston Harbor. Since 1996 it has formed part of the Boston Harbor Islands National Recreation Area. Managed by the Department of Conservation and Recreation, the island is home to the now-defunct Fort Andrews, active in harbor defense from 1904 to the end of World War II, on its eastern end, and a group of privately owned cottages on its western end. Campsites are also on the eastern end. Ferry service between Peddocks Island and Georges Island (where Fort Warren stands) is provided on a seasonal basis.
