I think it's worth going since you live in the city. I went there three years ago. As I remember, the harbor looks beautiful from the top of Cadillac Mountain, which is the highest mountain in the northeast coast. You can drive to the top of the mountain, just as you like. We went for lobster watching. This tour would let you learn something. What's structure of the cage to catch the lobster look like? How long will it take for a lobster to grow to be long enough for catching, otherwise they have to be set free? We also rent the kayak, and followed the guide riding in the harbor. I think you would enjoy the nature.
