Forget the rental car or Metro-North trip, all you need to go hiking is a MetroCard. Home to over 30,000 acres of parkland, New York City offers hundreds of nature trails to explore in parks across the five boroughs. New Yorkers do not have to travel very far to connect with the great outdoors, from the Staten Island Greenbelt, which is three times the size of Central Park, to ecologically diverse forests in Van Cortlandt Park, to the salt marshes of Marine Park Preserve. Ahead, discover some of the best trails to take a hike in every borough. Photo of Concrete Park by TheTurducken on Flickr
