How much time do you have? Bar harbour/acadia, boothbay harbor is many peoples favorite. Must go to lobster pounds....every day. If you have the time go to Portsmouth nh which is right on border. It is a really neat place. Others know more, but maine is great place.
If you go to acadia and want to hike let me know and I can give you a few tips.
Just for a long weekend. Aug 30-Sept 3
We are definitely hitting the lobster trail
I was thinking possibly a lighthouse tour? recommendations?
