Cliff Island is an island in Casco Bay Maine. It is part of the city of Portland, Maine. As of the 2000 census, the island had a year-round population is around 60 people. In the summer it can swell up to approximately 200. Originally named Crotch Island due to its H-shape and natural harbors. It is the only year-round inhabited island in Casco Bay with no paved roads. In the early 20th century the island's inns were a draw for summer tourists. There are now no hotels but many homes are available for weekly rentals or longer. While there are no public services residents enjoy a community hall, a tennis court, baseball field, and playground. The residents are served by a USPS Post Office, fire department, and one-room school for elementary grades. In 1987 the feature film The Whales of August was filmed entirely on location on Cliff Island. The buoy that was used in the film as a transitioning tool is now on display outside of the Casco Bay Lines Ferry Terminal. The film was among the last for stars such as Bette Davis, Lillian Gish, Vincent Price, and Ann Sothern. The cottage where the film was made is still owned by Frank Pitkin's family whose great grandmother, Josephine Pitkin, built the cottage named "Pitkin Point", in 1910.
