Rockland hot spots

Hi, I will be in Rockland for the first time on October 21st. I would love to hear from the locals and those who have made the trip as to where the hot spots are for photos of lobster villages, foliage color, and a great tour on a boat. I am excited to see as many lighthouses as we can and of course photograph them. This is a trip I have been waiting for for a long time. My husband and I are interested in a lobster tour in boothbay harbor which takes you on a trip to pull up traps, weigh and measure the lobsters etc. Is there anything like this out in Rockland?? We will be in boothbay and rockland only one day each. Looking forward to all your input. Semitegal
