Castle Forbes Bay is a small locality in the Huon Valley, Tasmania. It is part of the Huon Valley Council. Located on the shore of the Huon River, it is a primary agricultural region and was historically a center of apple growing. Apples would be shipped from the waterfront at Castle Forbes Bay to Hobart, for export. Castle Forbes Bay's landscape is still shaped by apple orchards, though many of them are now disused or empty of trees. A large number of pickers huts, garages and apple packings dot the scenery, considered the possibly best preserved orcharding landscape in Australia.
