We went there a couple of years ago, I don't believe we had to go thru the bay bridge tunnel. We live north on Philadephia and I think we went I95 to 495 to RT13 to Rt 301. I think or you may be able to pick up 301 off I95.Than it is right off 301, you will need to go over the Bay Bridge, but thats not the same as the Bay Bridge/tunnel. As far as the campground it was nice. Just that we went over a 4th of july weekend and it was packed. But it was nice,clean and the staff were friendly. Have a great time and eat some crabs!
