This 2.4-acre park floating above the Hudson appeared like a surrealist dream when unveiled in 2021: 132 concrete pods shoot from the water like tulips, crowned by undulating green hills, outdoor performance spaces and lookouts peering from pretty flower beds to Manhattan’s skyscraper forest. Snake along footpaths to enjoy gentle breezes and expansive views or check the seasonal event schedule to see live theater, music and dance with the rippling river as a backdrop.
