This famous outdoor + elevated park spanning 1.45 miles worth of city blocks in the Chelsea neighborhood, is a beautiful way to experience a breath of fresh air in a city that often lacks it. For those that don't know, the High Line is actually an old above ground rail road track converted into a lush green park + garden adorned with sculptures and many stop-offs along the way, and given that it's a public park, it's also free (one of the few free things in NYC).
