NJ/PA border
This park feels very PA to us with rolling hills, bald-top mountains to climb (some with fire towers), and lots of water to explore. Modern but simple amenities including showers and firewood for purchase. Individual sites were generously sized, shady, and relatively private thanks to the vegetation. Some sites are along the lake. The campground seemed pretty full in August. There are other campgrounds in this park if you can’t get reservations or a spot. Not far from NYC.
