Is it too early to see the fall leaves?
As far as your question about the foliage goes — you’ll be too early for “peak” foliage, but you might see a few leaves turning, especially if you drive away from the coast. The view of Camden and Passamaquoddy Bay from the top of the tower at Mt. Battie when the leaves are in full color is one of the most beautiful sights you can ever hope to see in New England. I will second lobstah’s recommendations of the Owl’s Head Transport Museum and the Farnsworth Museum. Just remember that the art museum in Rockland, not Rockport, even though Rockport is better known for its art community.
