Statue of Liberty National Monument Warnings and Dangers

Security is a must here, so be prepared. It is as tight as if you’re going into an air terminal before you board the ferry boats to go to Liberty Island and/or Ellis Island. She is one of our national treasures and we must protect her, so don't take offense if you have to follow security procedures.

They have security checks again before you are allowed to enter onto her platform too:
