Hello, this "campground" is basically a parking lot in Jersey City. Really the only way to access it is via 78 / New Jersey Turnpike Extension.
From my experience from traveling into NYC for pleasure as well as work traffic is always heavy since this is the same route you would take to get into NYC via the Holland Tunnel.
Hope this helps you out a little bit.
