One of the biggest surprises on this trip to New York was our visit to the High Line and the Chelsea Market. I'd even say that it is was probably the highlight of our trip.
Located on the lower west side, the High Line is a 1.6 KM aerial greenway that extends from Gansevoort St. (close to the 14th) and 34th. The path was built on top of a section of the former elevated freight railroad spur called the West Side Line. It is a wonderful green space with lots of water fountains, flowers, trees, tables and beach chairs. It feels surreal to walk along a suspended park in the middle of a very busy area of New York, the Meatpacking district. The view from there is also spectacular. You can see the water on the west side and the hustle and bustle of the Chelsea neighborhood on the east side. The High Line has tons of great architectural features and the visit is definitely worth your time.
The Chelsea Market is an enclosed food market built in the former factory complex where the Oreo cookie was invented and produced for decades. The stunning and newly renovated building is part of a large revitalization process of the Meatpacking District. Since there are lots of offices nearby, the market is packed 7 days a week. In the warmer months, people buy food at the market and have their lunches at the High Line. A pretty sweet plan, in my opinion.
It will only take you half a day to cover both places and when in New York, don't miss it. It is well worth the time.
