Welcome.
Renting a car in Bangor, Maine in September...perfect.
1.) Acadia National Park. Breathtaking. Take the light-house cruise excursion in Bar Harbor, worth every penny.
2.) Fletcher's Hill Stockton Springs; this is Sylvan Street and Church Street Free and breathtaking views of Stockton Harbor and Penobscot Bay.
3.) Camden Hills State Park. Amazing views of Camden Harbor and Knox County countryside. Watch the sailboats of all configurations up there.
4.) Penobscot Narrows Bridge Observatory. This is a tiny town called Prospect. Visit the Civil War era Fort Knox. The Bridge Observatory for amazing views.
5.) Liberty Craft Brewing; Liberty, Maine. Wonderful views and overall experience.
6.) In Bangor take a few photos of Paul Bunion.
Places to avoid:
1.) Downtown Camden. In my opinion chintzy tourist-trap non-sense. Camden Hills State Park must see, but the Village, skip it.
2.) Rockland area. Again with the chintzy garbage, save your money for the micro brews and wonderful wine tours in the country away from the coast.
3.) Belfast. Not much there. I was born there, I know. Hippies flocked there in the seventies and ruined it...they own it now.
Where to eat?
Sorry to say you're on your own there. Been trying to find reliable local fare for 45 years, always hit-or-miss. People know how to cook up here but the cheap SOBs
from away who own these restaurants won't pay em enough to work in the kitchens. My advise: save your money and stick with the national chains for meals. Kinda odd, but
a small variety store called "Andy's" in Warren on Route 1 is great food at a great price and serves really good fried seafood.
Where to stay?
The internet is your friend for accommodations. The internet will almost always trick you into eating at places that don't deserve your patronage, but lodging is good.
The best thing about Maine is that there no dangerous places to avoid. Relax and explore.
