If you drive east from Portland, through the craggy cliffs of Cape Elizabeth where Winslow Homer painted his coasts, along into Wiscassett, Rockland, Camden, Rockport and further still, you will hit the Blue Hill Penninsula. It is surrounded by the Bays of the Penobscot and Blue Hill as well as the Atlantic Ocean. Deer Isle is seperated from the coast by only a bridge yet you feel millions of miles from anything remotely close to civilization. If you want to feel small and yet quite large at the same time this is the place to go.
