Cliff Island is the smallest year-round island in Casco Bay and the last stop “down the bay” on the Casco Bay Lines ferry. Shaped like an “H,” the island has extensive property in conservation land, permanently protecting its rural atmosphere. The island is the only year-round island in Casco Bay that has all unpaved roads and, while cars are allowed, most people walk, bicycle or use golf carts for transportation.
