Away in Boston for a conference in late November, I decided to pair that with some holidays along the coast of Maine, and then to Cape Cod. Everybody was telling me it'd be wet and cold (well, 2 guys on the tripadvisor forum). In the end, I had brilliant weather, and Acadia National Park was gorgeous.
I started exploring the Southern coast of Maine. South of Portland, it's mainly lighthouses and rocky coastline. November equals not much wildlife, appart from a huge number of squirrels, both grey and red. Hiking is limited there, at least until I reached Camden Hills state park. From the hills you can see the ocean and the bays, but the autumn low hanging sun means pretty much from 7 am till 12 pm you got the sun in your face, not ideal for photos.
