Hi All,
Is there public transportation to and from EWR to Giant Stadium?

Not sure if they have buses directly from airport to the stadium. Check njtransit.com. If they don't, you can take a bus to the Port Authority, then they have special buses from the Port Authority that go directly to the stadium on game days.

I can't seem to find info about any bus or train service. almesq always gives good advice but in this case I think it would be really silly to have to go into NYC to Port Authority to go back out to the Meadowlands in NJ. There are a number of hotels near the Meadowlands that must have shuttle service from EWR. I would look at taking one of those or a taxi or a car service. While a doing a search for you I found this car service which looks ok

I agree that taxi or hotel shuttle would be great, but I was just trying to provide the information the op asked for regarding public transportation.

Thanks so much for the replies.
Will try car service. Donna
