My wife and I spent several vacations on the Maine beaches, in Lubeck, Machias, and Bailey Island. We will probably figure a way to get back there next summer. Campobello(or as my wife calls it Portobello) was a great day trip from the house in Machias.
That drive up the coast past Acadia, into the Canadian Maritimes (they call it "Down east"), is very scenic and wild. The Bay of Fundy has huge tide differentials. On Campobello there is a place where you can walk to a lighthouse on a nearby island in low tide. Unfortunately it was high tide when we got to that point, so could only look.
You can see the tide starting to roll out.
Yeah, I called it Portobello, too.
