I hope you have fun on your trip to Acadia. I used to live in Brunswick and also outside Bangor. If you are looking for some picturesque coastal pictures ( lobster traps, fishing boats, etc) then you may want to stop in the Casco Bay area. I remember taking a few trips to Bailey Island, and it was quite lovely. That was many years ago though (25 years). Slightly further north and east from the Casco Bay area you will run into Boothbay Harbor. I remember a few beautiful foggy mornings there.

It's hard to go wrong when travelling along the Maine coast. It's all so beautiful. Good luck!
