As you can see from the last photo, you don't get a great view of the Statue of Liberty from Battery Park, but you can get the Liberty or Ellis Island Ferry to get there. There are not a lot of parks in the Financial District of downtown NYC. This is a great place to escape the caverns of skyscrapers for a while, get some air, and enjoy the view. Something similar to what I said about Bryant Park in Midtown.
