Relaxed and healthy lifestyle exists in New York! Just less than an hour by train from Grand Central you can enjoy a wonderful day at Croton Gorge Park, a green venue at the base of a nice late nineteenth century dam that is still part of the New York water supply.
At Grand Central you can buy an $18 round-trip ticket to Ossining, a village in Westchester County. Once there, you can take a hiking route that used to be a slaves path during the American Civil War and also is the track of the former Croton Aqueduct, that was built in 1842 in order to improve water supply system conditions in New York City. During the walk you will be suddenly surrounded by a rush landscape of trees and small typical country American houses. You will also run into some brick conical towers that served as ventilation and to relieve pressure in the ducts underground.
After a couple hours or so walking you will reach Croton Gorge Park, where you can enjoy your deserved sandwich with your hiking friends while you enjoy the fantastic waterfall scene of the New Croton Dam.
After the day you will feel so comfortable after a nature trip in this crazy city…and also you will have learnt something new about New York water supply and its history.
