How is access at Musconetcong Gorge?

[CityGuyFishing]

I'm taking my 12 y/o nephew out fishing this weekend and Musconetcong Gorge is pretty convenient for our route. I've never been there. He isn't much of a hiker and we'll be fishing from the shore. Anyone know what the access is like there?
Or have any other good beginner spot recommendation along rt 78 toward PA? Even easy fish like sunnies are fine, just want to spend a few hours with the kid, and hopefully get a pic of him with a fish.

Thanks
