Absolutely! The crowds can be a little overwhelming sometimes, though most of the "leaf-peepers" tend to be on tour buses. I would suggest checking some Bed and Breakfast accomodations. There are some beautiful places to stay such as Booth Bay. I would also suggest going about 12 miles farther than Portland and stay at Freeport. It's the home of L.L. Bean and that tour can take 4 hours or more. Tour the outlet, come out to the outside waterfall and have an ice cream from the nearby Ben and Jerry's (I'd recommend Cherry Garcia). At any rate... it's a beautiful time in New England!...
