Getting here is half the fun.
Getting to and from Warwick is pretty easy! All three New York City airports are fine, but La Guardia is closest and nicest (really!), followed by Newark. If you fly into JFK, you’ll have to drive through the city, so your flight arrival time may have a big impact on the amount of traffic you hit.
Once you land, you have a few options for getting to Warwick:
NJ Transit (Bus)
Look, nobody wants to take the bus. But it’s cheap and easy, and since the buses leaving Port Authority Bus Terminal have their own lane through the Lincoln Tunnel, it’s pretty fast, too. You want the NJ Transit 197 bus to the Warwick Park & Ride. It usually departs from Gate 307.
Rent a Car!
Obviously this is the easier option, but be intentional about the time you intend to leave NYC. Everyone is leaving New York in the afternoons, when most flights would be arriving. The weekends are a little easier.
