This is certainly not a common place to visit in NY. If you have just a few days in the city, don’t bother. If you have plenty of time, you can just walk through mid-east Manhattan until you reach the East River Park.
You’ll find nice seal-shaped fountains decorating a plaza that emulates an ocean. You’ll probably make some squirrel friends if you have cookies. They are everything but shy.
And you can also enjoy the view of Williamsburg Bridge and the east river.
