There are several ways to see this beautiful harbor. One of the greatest views is from the Staten Island Ferry. Both the departure from Lower Manhattan and the approach to Lower Manhattan are fantastic. Another great view is from the Statue of Liberty and Ellis Island. Try looking over from the Brooklyn shore. Of course, the Verrazano Bridge has a great view of the Upper and Lower New York Bay.
The views from Battery Park across the Harbor towards New Jersey, Staten Island, and Brooklyn are are great. A walk along the Lower and East and West Sides of Manhattan are also fantastic.
There are several excursion boats and tours that sail the Harbor.
Do not miss the views of the Harbor.
