This former riverside landfill is now the best exhibition space for large-scale outdoor sculpture in the city. No velvet ropes and motion sensors here—interaction with the artwork is encouraged. It’s well worth a look, especially on a lovely day, and has a spectacular view of Roosevelt Island and the East Side of Manhattan. Check the website for the current exhibition schedule—or just let yourself be happily surprised. The park also offers outdoor movie screenings and free tai chi, Pilates, capoiera, and yoga classes in the summer. The Noguchi Museum is only about a block away, so you can swing by there as well.
