The High Line in New York City, New York

The High Line is a relatively recent addition to New York City. It opened partially in 2006 and opened completely in 2014. Once a functional train line used to carry goods, the above ground tracks are now repurposed as public space. Species of plants are picked specially for this park. There are benches, seasonal public programming, vendors near the 17th and 15th section of the park, and hidden nooks for you to explore.

It's a favorite spot of mine to bring friends to from out of town. It's open year round but the park is packed during the summer time. I've been in all seasons and find that the best time is bright and early in the morning during warmer seasons and noon time for colder seasons (the sun is warmest then) to beat the crowds. The vendors are closed in the winter so you'll have to bring your own hot beverage to keep your hands warm.
