The Manhattan Waterfront Greenway is a foreshoreway for walking or cycling, 32 miles (51 km) long, around the island of Manhattan, in New York City. The largest portions are operated by the New York City Department of Parks and Recreation. It is separated from motor traffic, and many sections also separate pedestrians from cyclists. There are three principal parts — the East, Harlem and Hudson River Greenways.
The Hudson River Greenway is the longest greenway in Manhattan, running along the West Side, from Dyckman Street in the north to Battery Park in the south, mostly through Riverside Park and Hudson River Park. A gap in West Harlem was filled in early October 2008 with the opening of the Harlem Piers bike lane. A roughly 10-block detour in the west 80s, where a walkway had crumbled into the river in the late 20th century, was eliminated on May 20, 2010, when the rebuilt section of greenway was opened.
The Hudson River Greenway is the most heavily used bikeway in the United States. The majority of it is close to Hudson River water level, except the portion north of George Washington Bridge where it climbs steeply, to approximately 160 feet (49 m) and includes Inspiration Point, with views of The Palisades in New Jersey across the river and of the George Washington Bridge to the south.
