I'm sure you know about Acadia NP on Mount Desert Island near Bar Harbor with a good road to the top of Mount Cadillac on a clear day you have beautiful views. We also liked the lighthouse, and lobster boat tours. You can get a CD of Acadia and to a self guided tour that will then allow you to take it in at your on pace, we packed a picnic lunch and ate while on rocks watching a huge blow-hole entertain us.
