With the Manhattan skyline, the Statue of Liberty and Ellis Island as a spectacular backdrop to this urban park, Liberty State Park is an extraordinary and unique public resource. The park hosts more visitors than any other in New Jersey, currently over 4 million/year, testament to the public's interest in this special place. Major festivals and other events are often held in the park. The historic Central Railroad of New Jersey Terminal (CRRNJ), a grand setting for much of New Jersey's transportation history in the northeast, sits prominently at the north end of the park. Liberty Walk, a 2 mile promenade, links a picnic area, interpretive center and the CRRNJ Terminal while presenting visitors with a sweeping view of the Hudson River. Liberty Science Center, a popular attraction for students and families, is located in the park's western section. Liberty State Park contains both estuarine and upland habitats. Herons, egrets, migratory shorebirds, and waterfowl utilize habitat at the park. In the winter, long-eared owls are often seen near the interpretive center. Liberty State Park was once an urban industrial area. As a result of this historical land use, the Division of Parks and Forestry has spent the past 25 years planning and building park infrastructure as well as remediating the site for public enjoyment. As part of the Division's waterfront improvement initiative for Liberty State Park, development of an 88 acre Green Park was completed in 1999. The Green Park is made up of crescent lawns, trails and landscaping improvements, including newly planted trees, shrubs and wildflower meadows. Approximately 4 miles of paved walkways have been added, as well as 7 plaza areas located along Liberty Walk, providing views of Ellis Island and the Statue of Liberty. The "Save Ellis Island!" initiative is meanwhile taking action to restore important historic features of the island where, long ago, immigrants to this country made their first stop.
