If you book well ahead you can get crown access tickets to the statue of liberty. I did it a couple of years ago and it was awesome: a nice climb up a narrow staircase and the rangers were very cool, too.

Another tip: rent bicycles and cycle around Manhattan and Brooklyn on the Waterfront Greenway. Not for the faint of heart since it's not entirely finished, so you're merging with traffic at some points.
