I just moved out of WIlliamsburg, but before I did I checked out a new park that has opened in the area. Located at the corner of N. 8th St and Kent Ave is a nice little park that allows you to walk right down to the East River and take in some amazing views of the Manhattan skyline. Before the park was officially there, people used to climb through fences to get down to that area. It's a great place to watch the sun go down over the city. I definitely recommend checking it out.
