Must visit, as it is a national monument and the skyline of new York visible from here is breath-taking.

You go here via a ferry, as it is on a separate island. This ferrry boarding has proper airport style security check so ensure you do not carry to much stuff.
Next you board ferry n HV this awesome ride to this island and get the best views of this monument.
Ensure you book tickets way in advance if you plan to go up-to crown of the monument, as those are limited tickets.
Best is the walk across island which is pretty huge and has captivating views.
