Tips from locals
If you are looking to do an island excursion for a nice meal with stunning views take the Casco Bay Lines to Diamond Cove (make a reservation in advance)
Take the ferry (casco bay lines) to Great Diamond Island and have a lovely meal al fresco. They time seatings to the ferry schedule.
