you can probably fish most anywhere, as long as you stay out of the way of the working boats (at this point in the summer, lobster fishermen usually don't have a whole lot of patience left.) there are wharfs around, and it's beautiful in webb's cove, where you will be camping. there is an awesome stone wharf there. i don't know if it's long past mackeral fishing time - i kinda lost track when my sons took my fishing rod away from me. (i suppose it was for a good reason, but they just aren't very sporting!)
