NYC has 29 hidden parks that if you are lucky enough to find, will feel like a breath of fresh air from the usual Central Park stroll. The Lotus Garden is a serene space located on the rooftop of a parking garage on the Upper West Side. Greenacre Park is also an urban respite with a 25-foot-high fountain wall. You can even explore uncovered NYC sites like The Little Red Lighthouse in Fort Washington Park. Talk about true tranquility!
