Governors Island, in the heart of New York Harbor, is only 800 yards from Lower Manhattan, and even closer to Brooklyn. The entire 92 acre National Historic District is open to the public for picnics, tours, concerts, car-free biking, and more. Open for public access on Fri, Sat and Sun. Take the free ferry from the Battery Maritime Building next to the Staten Island Ferry building, or take the ferry from the Fulton St ferry landing in Brooklyn (only on certain days). On Governors Island you are allowed to fish, picnic, play frisbee, lounge in a hammock, explore the history, or just go for a nice stroll. A Path Through History attraction.
