New York Harbor: Discover Iconic Landmarks and Parks

New York City is more than skyscrapers, bustling streets, and Broadway shows. From presidential landmarks and immigration history to shorelines perfect for outdoor recreation, the 12 National Parks of New York Harbor show you how the city has been a critical anchor in American history. The best part is the sites are woven into the city’s different neighborhoods.

You can easily walk between some. Others you’ll want visit by taking the subway or catching a taxi or uber. Some of the smaller sites are only open 5 days a week with limited hours. Some require guided tours. All are free to visit, except for ferry rides for two of the sites.

I’ve visited all of the 12 National Parks of New York Harbor, including 10 in just 2.5 days. I shared tips on how to do that in an AAA Trip Canvas article.

Below is the complete alphabetical list of the sites in New York Harbor, with a brief explanation of why each site is important and deserves a place on your New York itinerary.

African Burial Ground National Monument

One of the most significant archaeological discoveries in U.S. history, this sacred six-acre site preserves the remains of an estimated 15,000 free and enslaved Africans dating back to the 1600s and 1700s. It is the oldest and largest known excavated burial ground of its kind in North America and a powerful reminder of New York’s deep ties to slavery.

Castle Clinton National Monument

Located in Battery Park, Castle Clinton marks where New York City began. Built in the early 1800s as a fortification to protect the harbor during the War of 1812, it later served as America’s first immigration station and today functions as the ticket hub for Statue of Liberty and Ellis Island ferries.

Federal Hall National Memorial

This site stands at the birthplace of American democracy. You can see the slab George Washington stood on when he took the oath of office as the nation’s first president. This is where the First Congress passed the Bill of Rights, created the federal court system, and established the executive branch.

Gateway National Recreation Area

Spanning 27,000 acres across New York and New Jersey, Gateway is one of the largest urban parks in the country. Its beaches, marshlands, and historic military structures along the New York Harbor prove that outdoor adventure and green space exist well beyond Manhattan’s skyline. I took in a sunset from Canarsie Pier in the Jamaica Bay unit of Gateway.

General Grant National Memorial

This imposing mausoleum is the largest in North America and the final resting place of President Ulysses S. Grant and his wife Julia. It offers sweeping views of the Hudson River and insight into the life of the Civil War general who preserved the Union.

Governors Island National Monument

Governors Island reflects nearly two centuries of American military history, serving first as a U.S. Army base and later as a Coast Guard installation. While Castle Williams and Fort Jay close seasonally, the island itself remains open year-round for biking, picnicking, and harbor views.

Hamilton Grange National Memorial

Alexander Hamilton’s country estate sits today in St. Nicholas Park in Harlem. The site offers insight into the life of America’s first Secretary of the Treasury and the political foundations he helped shape. You can only see inside on free, ranger-led tours.

Lower East Side Tenement Museum (NPS Affiliated Site)

This affiliated site preserves two historic tenement buildings that housed more than 15,000 immigrants between 1863 and 2015. Guided apartment and walking tours bring immigration stories to life through the experiences of real families.

Saint Paul’s Church National Historic Site

Located 20 miles north of Manhattan, Saint Paul’s Church has anchored the Eastchester community since 1665. It played a role in early debates on freedom of religion and the press and served as a Revolutionary War field hospital. Its cemetery contains gravestones dating back to 1704.
