The Manhattan Waterfront Greenway is a waterfront greenway 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 non-profit organization Shorewalkers NYC, launched in 1982, works to promote and preserve the Manhattan waterfront. It organizes every year The Great Saunter, a 32-mile hike around Manhattan close to the waterline.
