Wow, Karen.. New England Lights. You could spend a month and do them all.

We went on 3 different motor coach tours this past fall.

1. Connecticut and Rhode Island
2. Cape Cod
3. Portland ME and south to Mass border.

These were all long days.

I think the most enjoyable was Cape Cod. Here we tried to at least view every lighthouse on the Cape. I think we missed a couple because of poor viewing.

Can you narrow down your request? Perhaps the number of days you plan to set aside for lighthouse looking?

BTW, the Connecticut lighthouses are, in general, a bit more difficult to find and view (private access, etc.) while Rhode Island's Lighthouses are almost all viewable. Maine takes great pride in its lighthouses.
