One of the most beautiful drives you can do in Acadia is along Park Loop Road in the Autumn. Colorful foliage lines your way, sometimes arching over as an autumn canopy of yellows, reds and oranges. Along the way, you'll see hundreds and hundreds of "Rockefeller teeth," the rectangular slabs of granite that act as guard rails.
I used a small point and shoot camera, held out the window of my car, as I drove down Park Loop Road from the start of the one-way road near Cadillac Mountain, almost to the Great Meadow. Enjoy.
