Why ride your bike on the busy streets when New York City contains more than 100 miles of bike paths? These tree-lined "greenways", maintained by the Department of Parks and Recreation, offer escape from cars and exhaust fumes, right on the island of Manhattan.
Ride riverside on the Hudson River Valley Greenway from the tip of Manhattan to the Upper West Side. This trail continues north all the way to Albany, some 150 miles away! Not ready for a major trek? Circumnavigate the island on the Manhattan Waterfront Greenway or ride from Coney Island to Fort Totten on the 40-mile Brooklyn-Queens Greenway.
For a little more nature, hit one of the city's mountain biking trails at Highbridge Park, in Manhattan, or Cunningham Park, in Queens. Greenways run throughout Manhattan, its boroughs, and New Jersey. Make sure to download the Park Department map before you go.
