Contact a Park Police officer or a park ranger if you notice any suspicious behavior or items. Vandalism (including graffiti) is a crime. Weapons of any kind are strictly prohibited. Smoking is prohibited indoors.

No, smoking is strictly prohibited on Ellis Island and Liberty Island, as well as on the ferries that transport visitors to these national monuments. As part of the National Park Service's effort to preserve historic structures and provide a healthy environment for the millions of tourists who visit each year, all forms of smoking, including e-cigarettes and vaping, are banned within the park boundaries. There are no designated smoking areas once you pass through the security screening at Battery Park or Liberty State Park. If you are a smoker, you will need to wait until you have returned to the mainland and exited the federal park zones. This policy is strictly enforced by park rangers to prevent fire hazards to the 19th-century buildings and to protect the air quality for all guests.
