Bulls Island's campground is no longer open. Other than that is a great place for hikes and kayacking.
There isn't a campground at this location, but the park is nice. It's right on the Delaware river in Stockton, NJ. They have a nice boat launch and some good fishing spots but the park itself is small if you wanted to make a weekend out of it. I took one star away because the bathrooms were out of toilet paper, but otherwise a good place for a day trip or picnic.
There is actually and island because there is a small waterway that breaks off of the river and then back into the river.
