It used to be just a highway running from the Upper West Side to the southern tip of Manhattan. But then came the creation of Hudson River Park in the late 90s, and ever since, this stretch of the island has been hugely popular among joggers, bikers, skaters and dogwalkers. A slew of brand new skyscrapers have brought thousands of city dwellers to this once unpopulated area. They enjoy tons of outdoor space and those spectacular views of the river… along with New Jersey on the other side. (You can’t have everything.)
