Hi Sunshine,
If you check the LI topics in this Forum you can get some good ideas to start.
See St Johns trip in August, as well as some of my trips.
The Orient Pt ferry from New London passes Avery Point, New London Harbor, New London Ledge, Orient Pt and Plum Island. On a clear day you can see Race Rock and Little Gulls in the distance. I think the ferry to Fishers Island will pass all of the above except Orient Pt and Plum Island, and add North Dumpling. If you land at Orient then you can get to Horton Pt, and take the ferries to Montauk and Cedar Pt.
As I said, look at past topics in this Forum for more ideas. List all for date range.
