Island retreat at the site of the former Fort McKinley on Diamond Island. Take the Casco Bay ferryboat to Diamond Island for a relaxing time at this fully renovated former Post Headquarters building offering many amenities and closeness to the pool, playground, bowling alley, gameroom and restaurant. Just a short walk to the ferry landing. Close to Portland and all it has to offer and yet it seems so far away in another world. Island living at it’s best. Restaurant and bar just a short walk away.
