My second-favorite outdoor-place in Manhattan. The abandoned 1.6 km rail tracks running above Chelsea down to the Meatpacking district were turned into an above-ground park. Perfectly nice place for sitting in the sun, reading, relaxing, having lunch in some green spot in the city. Nice views at the Hudson River, New Jersey, the Statue of Liberty (little small from there but still visible) and the architecture around Chelsea.
I often run to this place and I love this perspective on glittering Manhattan and the feeling of coolness in the air from being so close to the water. To sweat and breathe and see this view of New York gives me a sense of being in this great City.
