By car
Getting into Jersey City by car is not difficult, although finding parking once you are there may be. Street parking is very difficult to find, and many streets -- particularly in downtown Jersey City -- require parking permits to park for longer than a couple of hours. If you park in a permit zone, your car may be booted by the Parking Authority, especially if you have out-of-state plates.
Since Jersey City is located at the western end of the Holland Tunnel, your best bet is to take any highway that leads directly to it. On the New Jersey side, this includes Interstate 78 the Hudson County Extension of the New Jersey Turnpike, US 1-9, and Interstate 280. On the New York side, take the West Side Highway or Canal Street.
