It is now a historical national park and a museum.
Ellis Island is not a park, but a national historical site. Millions of immigrants came through it's doors from Europe so they could make a new life in the US. It is worth a visit.
In 1965, president Johnson issued a proclomation that gave the island to the National Parks Service, but it has only been giving tours to the public since 1976. http://www.history.com/content/ellis-island/timeline
