We visited as part of a guided tour of the Statue of Liberty and Ellis Island. We spent a lot of time after the guided tour just checking things out. If you are 16 yrs older and have closed toe shoes, you can do a Hard Hat Tour of the closer portions. We were not able to do that but it sounded awesome. Nicely kept grounds, lots of food stops and restrooms along with a remarkable piece of history. Don’t skip it if you’re going to the Statue of Liberty!
